Remove a workaround for MSVC 6.0.
...
That compiler is too ancient to support. And apparently, recent clang
complains about sprintf being deprecated.
Closes https://github.com/boostorg/integer/issues/36 .

Add support for modular build structure. ( #34 )
...
* Make the library modular usable.
* Switch to library requirements instead of source. As source puts extra source in install targets.
* Add requires-b2 check to top-level build file.
* Bump B2 require to 5.2
* Update copyright dates.
* Move inter-lib dependencies to a project variable and into the build targets.
* Update build deps.

Raised compiler requirements for Boost.Multiprecision tests.
...
This is needed to avoid compilation errors caused by Boost.Math, as
it requires a C++14 compiler now.

Implemented integer_log2 in terms of countl_zero from Boost.Core.
...
This allows to use compiler intrinsics and specialized hardware
instructions to compute log2, which results in better performance.
Also, added tests for the generic implementation using Boost.Multiprecision
integers.
Closes https://github.com/boostorg/integer/issues/31 .

Fixes for cxx11 changes to dependencies:
...
Make Multiprecision tests depend on <type_traits> and BOOST_NO_CXX11_HDR_TYPE_TRAITS.
Use specific Boost.Random headers and not <boost/random.hpp> as the latter pulls in some of Boost.Math which has now moved to C++11.

Added checks for C++11 features required by Boost.Multiprecision.
...
As of 2021, Boost.Multiprecision does not support C++03 and fails tests
of Boost.Integer. To mitigate, we replicate the preprocessor checks of
Boost.Multiprecision to disable its use in Boost.Integer tests in C++03
mode.

Embarcadero C++ clang-based compilers can not handle multiprecision comparisons in lightwieght tests, but gives a linker error. This has been reported to Embarcadero as a bug.

Fixed incorrect loop termination in lcm_range.
...
lcm_range used to incorrectly terminate on value of 1. Instead, it should
terminate on 0 since any further elements of the range no longer affect
the result of the function.
Also, added tests for the gcd_range and lcm_range functions verifying
that they terminate their loops at the correct points.

[ci skip] It is *not* the case that a discrete log exists when the base and modulus are coprime. Take 4^x = 2 mod 5 as a counterexample. Change API accordingly.
