arbitrary code before the handlers are invoked.

This resolves an issue with incorrect 304s on If-Modified-Since mod_include
requests since ap_meets_conditions() is not aware that this is a dynamic
request and it is not possible to satisfy 304 for these requests (unless
xbithack full is on, of course).  When mod_include runs as a filter, it is
too late to set any flag since the handler is responsible for calling
ap_meets_conditions(), which it should do before generating any data.

If a module doesn't need to run such arbitrary code, it can just pass NULL
as the argument and all is well.

  These emits occur mainline, outside of the pphrase_callback, so we never
  opened readtty or writetty.  But they are absolute failures, nothing the
  user could do to deal with them.  They are logged in the ssl vhost's error
  log.

  In this case, I forgot my SSLCertificateKeyFile, so the server never
  tried the callback.  writetty wasn't initialized, so we segfaulted.

  This segfault is due to misconfig, not to the dialog with the user.
  This is the easiest fix (easier to read, too), but we shouldn't need
  to worry too much that the release is tagged.  If we retag, fine, then
  grab it, but it only addresses a config problem.

Not only should it just say "can't do that on win32," which is after all
the bottom line, it was spitting out openssl error messages which were
totally useless.  Eg:

[30/May/2002 17:31:17 05760] [error] Init: PassPhraseDialog BuiltIn not
supported in server private key from file
F:/Apache/Apache2/conf/ssl/secure.key (OpenSSL library error follows)
[30/May/2002 17:31:17 05760] [error] OpenSSL: error:0D084069:asn1
encoding routines:d2i_ASN1_SET:bad tag
[30/May/2002 17:31:17 05760] [error] OpenSSL: error:0D09D082:asn1

[30/May/2002 17:31:17 05760] [error] OpenSSL: error:0D09B00D:asn1
encoding routines:d2i_PrivateKey:ASN1 lib

Which is essentially saying "OpenSSL couldn't read your private key because
it was encrypted, and we can't get the passphrase the way you asked us to
on this platform."

It's totally unsafe to use apr_pool_userdata_setn() in the post_config
phase of a module, since on some platforms when the DSO gets reloaded
between phases, the data segment will be at a different address on the
second phase and the userdata_get() call will fail.

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.

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 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.
