Re-allow SSL passphrase prompt at server start, but not thereafter.
Leave OpenSSL's default passphrase collection callback in place during
the first call of secure_initialize() in server startup. Although that
doesn't work terribly well in daemon contexts, some people feel we should
not break it for anyone who was successfully using it before. We still
block passphrase demands during SIGHUP, meaning that you can't adjust SSL
configuration on-the-fly if you used a passphrase, but this is no worse
than what it was before commit de41869b6. And we block passphrase demands
during EXEC_BACKEND reloads; that behavior wasn't useful either, but at
least now it's documented.
Tweak some related log messages for more readability, and avoid issuing
essentially duplicate messages about reload failure caused by a passphrase.
