Added API in lightweight_test to obtain the number of test failures.

The new API allows to check if the number of check failures satisfies
a certain condition. The report_errors function returns test_report,
which allows to obtain the error count. It also protects against
unintended comparisons to the error count, which was a misconception
before.

Also added a get_error_count function to explicitly query for the current
number of errors.

-
-[simplesect Authors]
-
-* Glen Fernandes

-
-[section Overview]
-
-The header `<boost/core/allocator_access.hpp>` provides the class and function
-templates to simplify allocator use. It provides the same functionality as the
-C++ standard library `std::allocator_traits` but with individual templates for
-each allocator feature.
-
-These facilities also simplify existing libraries by avoiding having to check
-for `BOOST_NO_CXX11_ALLOCATOR` and conditionally use `std::allocator_traits`.
-
-[endsect]
-
-[section Examples]
-
-The following example shows these utilities used in the definition of
-an allocator-aware container class:
-
-```
-template<class T, class A = boost::default_allocator<T> >
-class container
-    : boost::empty_value<typename boost::allocator_rebind<A, T>::type> {
-public:
-    typedef T value_type;
-    typedef A allocator_type;
-    typedef typename boost::allocator_size_type<A>::type size_type;
-    typedef typename boost::allocator_difference_type<A>::type difference_type;
-    typedef value_type& reference;
-    typedef const value_type& const_reference;
-    typedef typename boost::allocator_pointer<A>::type pointer;
-    typedef typename boost::allocator_const_pointer<A>::type const_pointer;
-    // ...
-};
-```
-
-In C++11 or above, aliases such as `boost::allocator_pointer_t<A>` can be used
-instead of `typename boost::allocator_pointer<A>::type`.

-
-`template<class To, class From> To bit_cast(From const& from) noexcept;`
-
-* *Requires:* `To` and `From` must be trivially copyable and `sizeof(To)` must be the same as `sizeof(From)`.
-* *Returns:* A value of type `To` with the storage bytes copied from `from`.
-
-[endsect]
-
-[section Integral powers of 2]
-
-`template<class T> constexpr bool has_single_bit(T x) noexcept;`
-
-* *Requires:* `T` must be an unsigned integer type (i.e. one of `unsigned char`, `unsigned short`, `unsigned int`, `unsigned long`, `unsigned long long`).
-* *Returns:* `true` if `x` is an integral power of two, `false` otherwise. (`has_single_bit(0u)` is false.)
-
-`template<class T> constexpr T bit_ceil(T x) noexcept;`
-
-* *Requires:* `T` must be an unsigned integer type.
-* *Returns:* The smallest integral power of 2 greater than or equal to `x`. If this value is not representable in `T`, behavior is undefined.
-
-`template<class T> constexpr T bit_floor(T x) noexcept;`
-
-* *Requires:* `T` must be an unsigned integer type.
-* *Returns:* If `x == 0`, 0; otherwise the maximal value `y` such that `has_single_bit(y)` is `true` and `y <= x`.
-
-`template<class T> constexpr T bit_width(T x) noexcept;`
-
-* *Requires:* `T` must be an unsigned integer type.
-* *Returns:* If `x == 0`, 0; otherwise one plus the base-2 logarithm of `x`, with any fractional part discarded.
-
-[endsect]
-
-[section Rotating]
-
-In the following descriptions, `N` denotes `numeric_limits<T>::digits` and `r` denotes `s % N`.
-
-`template<class T> constexpr T rotl(T x, int s) noexcept;`
-
-* *Requires:* `T` must be an unsigned integer type.
-* *Returns:* If `s` is negative, `rotr(x, -s)`; if `r` is 0, `x`; if `r` is positive, `(x << r) | (x >> (N - r))`.
-
-`template<class T> constexpr T rotr(T x, int s) noexcept;`
-
-* *Requires:* `T` must be an unsigned integer type.
-* *Returns:* If `s` is negative, `rotl(x, -s)`; if `r` is 0, `x`; if `r` is positive, `(x >> r) | (x << (N - r))`.
-
-[endsect]
-
-[section Counting]
-
-`template<class T> constexpr int countl_zero(T x) noexcept;`
-
-* *Requires:* `T` must be an unsigned integer type.
-* *Returns:* The number of consecutive 0 bits in the value of `x`, starting from the most significant ("left") bit.
-
-`template<class T> constexpr int countl_one(T x) noexcept;`
-
-* *Requires:* `T` must be an unsigned integer type.
-* *Returns:* The number of consecutive 1 bits in the value of `x`, starting from the most significant bit.

-
-* *Requires:* `T` must be an unsigned integer type.
-* *Returns:* The number of consecutive 1 bits in the value of `x`, starting from the least significant bit.
-
-`template<class T> constexpr int popcount(T x) noexcept;`
-
-* *Requires:* `T` must be an unsigned integer type.
-* *Returns:* The number of 1 bits in the value of `x`.
-
-[endsect]
-
-[section Endian]
-
-Under C++11, `endian` is defined as `enum class endian` as shown in the synopsis. Under C++03, its definition is
-
-``
-namespace endian
-{
-enum type
-{
-    little = see below,
-    big = see below,
-    native = see below
-};
-}
-
-typedef endian::type endian_type;
-``
-
-The values of `endian::big` and `endian::little` are distinct. `endian::native` is equal to `endian::big` on
-big endian platforms, equal to `endian::little` on little endian platforms, and a distinct value on platforms
-that are neither.
-
-Note that you should not rely on `little` and `big` having any specific values, because the C++20 standard
-leaves these unspecified.

-[section Revision History]
-
-[section Changes in 1.78.0]
-
-* Added a generic implementation to `boost/core/cmath.hpp`, enabled when `BOOST_CORE_USE_GENERIC_CMATH`
-  is defined or when the platform does not provide the necessary facilities in `<cmath>`.
-* Added `boost::core::type_name`, a utility function that returns the name of a type as a string.
-* Added `boost::span`, a C++11 implementation of C++20's `std::span`.
-
-[endsect]
-
-[section Changes in 1.77.0]
-
-* `boost/core/uncaught_exceptions.hpp` has been modified for compatibility with Mac OS 10.4 and older.
-
-[endsect]
-
-[section Changes in 1.76.0]
-
-* Added implicit conversion between compatible reference wrappers.
-* Added `boost/core/cmath.hpp`, a portable implementation of the floating point classification functions from `<cmath>`.
-* Added `boost/core/bit.hpp`, a portable implementation of the C++20 standard header `<bit>`.
-* Fixed `BOOST_TEST_EQ`, `BOOST_TEST_NE` for character types under C++20.
-* Revised allocator access utilities (now support VS2013, and no workarounds use `allocator_traits`.)
-
-[endsect]
-
-[section Changes in 1.74.0]
-
-* Implemented the allocator access utilities which provide a replacement for `allocator_traits`
-  with individual traits and functions for each facility. They support the C++11 allocator model
-  when possible and provide a fallback for C++98 compatibility.
-* Added `BOOST_TEST_WITH` to Lightweight Test.
-
-[endsect]
-
-[section Changes in 1.71.0]
-
-* Added functions `alloc_construct`, `alloc_construct_n`, `alloc_destroy`, and `alloc_destroy_n`
-  in `<boost/core/alloc_construct.hpp>` for allocator aware and exception safe construction and
-  destruction of objects and arrays.
-* Added constexpr functions `first_scalar` in `<boost/core/first_scalar.hpp>` for obtaining a pointer
-  to the first scalar element of an array. Given a pointer of type `T*` they return a pointer of type
-  `remove_all_extents_t<T>*`.
-* Added class template `noinit_adaptor` in `<boost/core/noinit_adaptor.hpp>` which is an allocator adaptor
-  that converts any allocator into one whose `construct(ptr)` performs default initialization via placement
-  `new`, and whose `destroy(ptr)` invokes the `value_type` destructor directly.
-* Added class template `default_allocator` in `<boost/core/default_allocator.hpp>`, which can serve as a minimal
-  default allocator that has interface similar to C++20 `std::allocator`, supports configurations with disabled
-  exceptions and does not have `std` as an associated namespace. The allocator uses `operator new` and
-  `operator delete` for allocation.
-* In `<boost/core/uncaught_exceptions.hpp>` header, added workarounds for better compatibility with QNX SDP 7.0
-  when libc++/libc++abi libraries are used.
-* The `<boost/detail/sp_typeinfo.hpp>` header is now marked as deprecated and will be removed in a future release.
-  `<boost/core/typeinfo.hpp>` should be used instead.

-* Implemented `boost::empty_value`, for library authors to conveniently leverage the Empty Base Optimization to
-  store objects of potentially empty types.
-* Implemented `boost::quick_exit` to provide the C++11 standard library facility `std::quick_exit` functionality.
-* Reduced the number of statics in Lightweight Test, and employ lighter abort behavior for MSVC compilers upon
-  failure to call `boost::report_errors`.

-[section Overview]
-
-This header <boost/core/span.hpp> provides class template `span`, which is a
-view over a sequence of objects. It implements the C++20 standard library
-`std::span` facility. This implementation supports C++11 and higher.
-
-In addition to referencing the sequence of objects, the span knows the count of
-objects. There are two kinds of spans:
-
-* Dynamic size (`span<T>` or `span<T, dynamic_extent>`)
-* Static size (`span<T, N>`)
-
-Dynamic size spans have a count that can be a value known at run time. Static
-size spans have a count that must be known at compile time.
-
-[endsect]
-
-[section Examples]
-
-The following snippet shows a function to compute a SHA1 hash whose parameters
-and return type use spans.

-```
-auto sha1(boost::span<const unsigned char> input,
-    boost::span<unsigned char, SHA_DIGEST_LENGTH> ouput)

-[section Header <boost/core/string_view.hpp>]
-
-The header `<boost/core/string_view.hpp>` defines `boost::core::string_view`,
-a portable and interoperable implementation of `std::string_view`.
-
-Unlike `boost::string_view`, `boost::core::string_view` has implicit
-conversions from and to `std::string_view`, which allows Boost libraries that
-support C++11/C++14 to use it in interfaces without forcing users to forgo the
-use of `std::string_view` in their code.

-[section Header <boost/core/type_name.hpp>]
-
-The header `<boost/core/type_name.hpp>` defines the function
-template `boost::core::type_name<T>()` that returns a string
-representation of the name of `T`, suitable for logging or
-diagnostic display purposes.
-
-The result is similar to `boost::core::demangle( typeid(T).name() )`,
-but it's made more regular by eliminating some of the platform-specific
-differences and extra template parameters of the standard library
-container types.
-
-For example, `type_name< std::map<std::string, int> >()` returns
-`"std::map<std::string, int>"` and not
-
-```
-  std::map<std::__cxx11::basic_string<char, std::char_traits<char>,
-    std::allocator<char> >, int, std::less<std::__cxx11::basic_string<char,
-    std::char_traits<char>, std::allocator<char> > >, std::allocator<
-    std::pair<std::__cxx11::basic_string<char, std::char_traits<char>,
-    std::allocator<char> > const, int> > >
-```
-
-or
-
-```
-  class std::map<class std::basic_string<char,struct std::char_traits<char>,
-    class std::allocator<char> >,int,struct std::less<class std::basic_string<
-    char,struct std::char_traits<char>,class std::allocator<char> > >,class
-    std::allocator<struct std::pair<class std::basic_string<char,struct
-    std::char_traits<char>,class std::allocator<char> > const ,int> > >
-```
-
-The return values aren't guaranteed to be stable across Boost releases.
-
-Compilation with `-fno-rtti` is supported, but the returned type names aren't
-guaranteed to be particularly useful or unique.
