Remove some complier warnings from msvc in compat/mingw.c for value
truncation from 64 bit to 32 bit integers.
Compiling compat/mingw.c under a 64 bit version of msvc produces
warnings. An "int" is 32 bit, and ssize_t or size_t should be 64 bit
long. Prepare compat/vcbuild/include/unistd.h to have a 64 bit type
_ssize_t, when _WIN64 is defined and 32 bit otherwise.
Further down in this include file, as before, ssize_t is defined as
_ssize_t, if needed.
Use size_t instead of int for all variables that hold the result of
strlen() or wcslen() (which cannot be negative).
Use ssize_t to hold the return value of read().

These two header files are included from ordinary source files that
already include <git-compat-util.h> as the first header file as they
should. There is no need to include the compat-util in these
headers.
"make hdr-check" is not affected, as it is designed to assume that
what <git-compat-util.h> offers is available to everybody without
being included.

To help pinpoint the source of a regression, it is useful to know some
info about the compiler which the user's Git client was built with. By
adding a generic get_compiler_info() in 'compat/' we can choose which
relevant information to share per compiler; to get started, let's
demonstrate the version of glibc if the user built with 'gcc'.
