Fix crashes on MS-Windows during dumping
* src/unexw32.c (get_section_info): Make extra_bss_size be the
maximum of extra_bss_size and extra_bss_size_static. This avoids
computing the size of the output file smaller than it actually
needs to be, which then causes copy_executable_and_dump_data to
write beyond the requested size of the file mapping, thus relying
on the OS roundup to page boundary to save us from ourselves. See
http://lists.gnu.org/archive/html/emacs-devel/2016-12/msg00642.html
for the details.
* lib/stdio-impl.h: Revert the workaround fix of not including
errno.h for MinGW.
