Add context pointer as first arg for the other function types.

storage providers; includes a significant change to the shmcb storage
structure:
* modules/ssl/ssl_private.h (modssl_sesscache_provider): Change
retrieve function to take dest/destlen output buffer, to take a
constant id paramater, and to return a BOOL.
* modules/ssl/ssl_scache.c (ssl_scache_retrieve): Update accordingly,
perform SSL deserialization here.

modules/ssl/ssl_scache_dbm.c (ssl_scache_dbm_retrieve),
modules/ssl/ssl_scache_memcache.c (ssl_scache_mc_retrieve):
Update accordingly.
* modules/ssl/ssl_scache_shmcb.c: Store the whole ID in the cache
before the data, so that each index can be compared against the
requested ID without deserializing the data. This requires approx
20% extra storage per session in the common case, though should
reduce CPU overhead in some retrieval paths.
(SHMCBIndex): Replace s_id2 field with id_len.
(shmcb_cyclic_memcmp): New function.
(ssl_scache_shmcb_init): Change the heuristics to allow for increase
in per-session storage requirement.

(shmcb_subcache_store): Store the ID in the cyclic buffer.
(shmcb_subcache_retrieve, shmcb_subcache_remove): Compare against
the stored ID rather than deserializing the data.
(ssl_scache_shmcb_retrieve, ssl_scache_shmcb_store): Update
accordingly.

'store' interface to take a data/length pair rather than an
SSL_SESSION pointer.

session here and pass down the raw DER.
* modules/ssl/ssl_scache_dc.c, modules/ssl_scache_mc.c,
modules/ssl_scache_shmcb.c, modules/ssl_scache_dbm.c: Adjust ->store
implementations accordingly, removing the four sets of identical
code doing the i2d dance.

step towards use of the ap_provider interface:
* modules/ssl/ssl_private.h (modssl_sesscache_provider): Add new
vtable type.
(SSLModConfigRec): Reference the vtable here.
Replace all the ssl_scache_* prototypes with provider vtable objects.
* modules/ssl/ssl_scache.c (ssl_scache_init, ssl_scache_kill,
ssl_scache_retrieve, ssl_scache_store, ssl_scache_remove,
ssl_ext_status_hook): Use callbacks from vtable rather than ifdef
spaghetti.
* modules/ssl/ssl_engine_init.c (ssl_init_ctx_session_cache):
Only install the OpenSSL callbacks if a vtable is configured.
* modules/ssl/ssl_engine_config.c (ssl_cmd_SSLSessionCache): Set up
vtable pointer.
* modules/ssl/ssl_scache_dc.c, modules/ssl_scache_mc.c: Adjust to make
implementations static, and add vtable definition.
* modules/ssl_scache_shmcb.c: Likewise; also move the init
one-per-process requirement down here.
* modules/ssl_scache_dbm.c: Likewise; also (temporarily) use a local
subpool in the store callback.

to be included even when mod_ssl is not enabled.
* Makefile.in (install-include): Only install mod_ssl.h.
* modules/ssl/ssl_private.h: New file.
* modules/ssl/mod_ssl.h: Move everything apart from than the optional
hook definitions into ssl_private.h.
* modules/ssl/*.c: Include ssl_private.h not mod_ssl.h
* modules/ssl/config.m4: Always add the mod_ssl directory to the
include path so other modules can find mod_ssl.h.
* modules/proxy/mod_proxy.c: Include mod_ssl.h to pick up the optional
hook definitions rather than copy'n'pasting them.

data corruption bugs since being apr_rmm'ified.
* config.m4, mod_ssl.dsp: Don't build ssl_util_table and
ssl_scache_shmht.

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.

latest patches from Madhusudan which makes mod_ssl 95% working inside
Apache 2.0. There is still a lot of more work (both porting and cleanup)
to do be done. See modules/ssl/README for details.

If we want this later again, we have to do it differently anyway. So,
for now we try to strip down mod_ssl as heavy as possible and hence we
kick out this stuff at all.
