Re: pgsql: Add API functions to libpq to interrogate SSL related stuff.

This patch is one large brick shy of a load: it creates exported libpq
functions but fails to ensure they always exist. That's why jacana is
unhappy; though TBH I'm astonished that any non-ssl-enabled builds
are passing. Apparently missing library functions are less of a hard
error on Linux than they ought to be.

I think probably the exported functions need to be defined in fe-exec.c
or fe-connect.c, with bodies along the lines of

#ifdef USE_OPENSSL
call OpenSSL-specific function
#else
return NULL
#endif

(or whatever's appropriate when no SSL support). We do want these
functions to exist even in non-SSL-enabled builds.
