Moved SHLIB_NAME definition into one place.

Switch to OpenPAM. Bump library version. Modules are now versioned, so
applications linked with Linux-PAM will still work.
Remove pam_get_pass(); OpenPAM has pam_get_authtok().
Remove pam_prompt(); OpenPAM has pam_{,v}{error,info,prompt}().
Remove pam_set_item(3) man page as OpenPAM has its own.

Remove NO_WERROR, now that WARNS=n is gone.

WARNS=4 fixes. Protect with NO_WERROR for the modules that have
warnings that are hard to fix or that I've been asked to leave alone.

Clean up (and in some cases write) the PAM mudules, using
o The new options-processing API
o The new DEBUG-logging API

Add man(1) pages for ALL modules. MDOC-Police welcome
to check this.

Audit, clean up while I'm here.

Big module cleanup.

Move common stuff into Makefile.inc, and tidy up all the Makefiles
as a result.

Build new modules.

Put a commented-out dependancy on libpam for the (shared) modules.
I can't bring this in just yet, as the dependancy (modules->libpam)
is reversed for the static case (libpam->modules).

Use a unified libgcc rather than a seperate one for threaded and
non-threaded programs. This provides threaded programs with the
needed exception frame symbols.
