Fix bug #12878 with compilation failure with Visual C++ 11.0.

 src/w32select.c: Include w32common.h before w32term.h, so that
 windows.h gets included before w32term.h uses some of its
 features, see below.
 src/w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New
 typedefs.
 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New
 prototypes.
 (EnumSystemLocales) [_MSC_VER]: Define if undefined.
