std::strlen is computed at compile time if possible by the compiler. So

Because there a limited resources to watch files we watch now directories.
So we need much less resources.

Testable on Linux/macOS by changing c++14 to c++1z in qtcreator.pri.
Testable with latest MSVC2017 by setting _CL_=/std:c++17.
unary_function, binary_function, and a few other things that were
deprecated are removed in C++17.
std::string got a non-const overload for its "data" member function,
so we cannot create a function pointer on it without specifying its
type. Use std::declval instead (though it requires a default constructor
for the type).
MSVC seems to have an issue with Utils::transform for std::vector
(used in Nim plugin), but that looks like a compiler issue.

The small string control block moved to the beginning, so it is more cache
local. The control block is cleanup too, so it should be easier to read.
The alignment is removed because it is creating to big holes.

used to construct a SmallString and a SmallStringView.

The database is using file path integer ids to handle file paths because
otherwise we would save many redundant data. This patch is improving it
further with the introduction of a database based file path cache. The
entries are now divided in a directory path and file name. This is quite
handy for directory based file watching.

std::size_t is a undefined unsigned integer type and std::ptrdiff_t is a
undefined signed integer type. So sometimes the compiler doesn't know
which to choose because both could represent a integer.

SmallString is a very simple utf8 string class. It's purpose is performance.
It uses a short string opimization which provides 31 bytes of heap free
memory to save a 30 bytes long string plus null terminator. If the string
gets larger heap is allocated. The grow strategy is 1.5 to improve reuse
of allocated memory.
It uses optionally constexpr to provide string literals.
