Remove unused typedefs and macros from _G_config.h

[Joseph S. Myers]

This patch removes various unused typedefs and macros from
_G_config.h.  None of these _G_* typedef or macro names are used
anywhere in glibc.

Tested x86_64 that the code generated for glibc's shared libraries is
the same before and after the patch.
