Add a configure check to see if the seeker function in an fopencookie
uses off_t or the newer, more portable "fpos_t *".
The check could perhaps be more refined, as the test program will segfault

Fix the framework support

Support compiling and linking against Darwin / Mac OS X frameworks

- Fixed bug: #18560, the macro was not defined always.

Made PHP_ADD_LIBPATH use the $ld_runpath_switch and changed the Darwin
link lines in sapi/cli and sapi/cgi to use $NATIVE_RPATHS.
This is a tentative fix for #18450.

Improve/fix handling of --disable-rpath

Might or might not fix #18374

We include the proper header files now in the check. (me)

3. The nsl/bind/socket/etc checks have been rewritten using PHP_CHECK_FUNC.
This ensures that no extra library is used, if the symbol is
available in libc which avoids issues on BSD/OS, OpenBSD and others.

"-" is not acceptable in a #define (i have since discovered). converting all - to _ is the right thing to do.
