The issue is that ssl_log doesn't handle apr_status_t result codes.  This
leads to a number of places (esp. with mutexes) where the error codes get
lost.  Rather than extending ssl_log further, since mod_ssl is part of
our core, migrate to ap_log_error.  This means that mod_ssl no longer
does its own logging.

Most uses of SSL_ADD_ERRNO are now mapped correctly to apr_status_t values
(mainly because the APIs that used to return errnos are now APRized and
have apr_status_t codes available).

SSL_LOG_TRACE and SSL_LOG_DEBUG were mapped to the APLOG_DEBUG values.
mod_ssl prints out a LOT of debugging information, so mod_ssl with LogLevel
Debug may not be a good idea - perhaps mod_ssl should be less chatty.

Numerous printf type collisions were also resolved.

(The ssl logging code itself will be removed in a subsequent commit.)

This has been discussed on dev@httpd, but the fact that there isn't
much to review besides the mindless changes, I'm going to commit now
and rely on CTR if I screwed up anything on the translation.

ssl_log_ssl_error() function that wraps ap_log_error instead.

This begins the migration from ssl_log() -> ap_log_error().  Divorcing
ourselves from the SSL_ADD_SSLERR option is required to make the next
pass easier.

This is waiting for a proper APR interface, but this does not mean that

This is admittedly rather ugly code to come up with a unique 4-byte
identifier for the thread.  Since our threads are pthreads and a pthread
maps 1:1 to a TCB, the address of the TCB is sufficient.   Yes, every
TCB sees a different piece of real storage mapped to the first page,
so the code does make sense.

at this point, so the \r\n\r\n just confuses the http input filter.

One concern: this patch is only correct as long as we only ever call this
function while in AP_MODE_GETLINE.  Ideally we would account for the mode
and return the newlines if not in GETLINE mode, but at the moment it doesn't
seem to matter.
