[PATCH] enable -finline-functions optimization

[Thomas Pfaff]

This patch enables inline optimization for the c++ source files
in winsup/cygwin.

I tried several attributes for std_dll_init, wsock_init and
unused_sig_wrapper without success, the only working solution was to
change the functions from static to global to avoid its removal.

And the new_muto in the pwdgrp constructors can not be inlined for more
than one instance.

To enable -finline-functions optimization run "make CYGINLINE=1".

The performance win may vary, at least the rwlock7 test runs about 15%
faster.

I am running cygwin with this patch about one week now, seems to be
stable.
