The old way using getpwuid could cause problems in programs that enable
reading from netrc files simultaneously in multiple threads.

This previously caused a fatal error (with a confusing error code, at
that).

Reported by: Glen A Johnson Jr.

The AES-GCM ciphers were added to GnuTLS as late as ver. 3.0.1 but
the code path in which they're referenced here is only ever used for
somewhat older GnuTLS versions. This caused undeclared identifier errors
when compiling against those.

This seems to have become necessary for SRP support to work starting
with GnuTLS ver. 2.99.0. Since support for SRP was added to GnuTLS
before the function that takes this priority string, there should be no
issue with backward compatibility.

This makes the behaviour consistent with what happens if a date can
be extracted from the certificate but is expired.

This prevents valgrind from reporting possibly lost memory that NSPR
uses for file descriptor cache and other globally allocated internal
data structures.

This feature was unintentionally disabled by commit ff92fcfb.
