All supported systems have locale_t.
locale_t is defined by POSIX.1-2008 and SUSv4, and available on all
targeted systems. For Windows, win32_port.h redirects to a partial
implementation called _locale_t. We can now remove a lot of
compile-time tests for HAVE_LOCALE_T, and associated comments and dead
code branches that were needed for older computers.
Since configure + MinGW builds didn't detect locale_t but now we assume
that all systems have it, further inconsistencies among the 3 Windows build
systems were revealed. With this commit, we no longer define
HAVE_WCSTOMBS_L and HAVE_MBSTOWCS_L on any Windows build system, but
we have logic to deal with that so that replacements are available where
appropriate.
