Solve SSL-C breakage introduced in mod_ssl.h rev 1.129 and
ssl_engine_kernel.c rev 1.88. SSL* is not const under SSL-C.
I've confirmed Jeff's comment that the original patch doesn't harm
earlier OpenSSL versions which declared no arguments at all.
I suspect now that we could fold
#define MODSSL_BIO_CB_ARG_TYPE const char
#define MODSSL_CRYPTO_CB_ARG_TYPE const char
#define MODSSL_INFO_CB_ARG_TYPE const SSL*
into a single MODSSL_CB_ARG_CONST define, but this works for now.
Move the dropped '--enable-layout' subdir logic into APR_SUBDIR_CONFIG macro
as a third parameter rather than manually computing it ourselves.
Add the ' prefix'd --enable-layout so that this can work with an autoconf-2.54+
generated configure. (Previously, the option would not be dropped with 2.54
or 2.57 since it unconditionally adds single-quotes which our case statement
would not catch.)
Try to shorten long invocations of APR_SUBDIR_CONFIG where possible.

Reapply the fix *intended* by rev 1.79 in a safer manner. Prior to
all assignments and the final SSL_free(), free ssl_conn->client_cert
to avoid leaks of this refcounted X509*. Prereleasing refcounted
objects is unsafe programming; fix applied to both branches.
EVP_PKEY_free() is refcounted on OpenSSL, but NOT under RSA SSL-C.
Eliminate a number of test failures by conditionally reverting rev 1.79
pubkey handling in ssl_engine_kernel.c, except under OpenSSL.
Also revert a rev 1.79 bogisity for all toolkits; it's entirely bogus
to release a refcount after setting aside the results in a persistant
structure, in this case sslconn->client_cert from SSL_get_peer_certificate()
mustn't be freed while sslconn is still in play. The proper patch (not
written yet) is to invoke the X509_free(sslconn->client_cert) when we
cleanup the sslconn structure.
A cosmetic change to 1.79 - a real X509 *cert is in play, don't use
that same variable to retrieve/release the quick lookup and discard
of the peercert.

Fix a serious bug where the 'next' generation of the server would open
a brand new mutex. This patch creates a single mutex in the first config
phase that survives for the life of the server (server->process->pool).
Now one server generation to the next will respect the same mutex between
one another, while the previous generation is still mopping up.
Allow any mutex to accept a 'filename' ... and always root it to the
server root unless we are using posixsem, which can't handle big paths.
This reorganization should make the code much more readable because
all of the common code is at the beginning and end of the function,
simplifing the long conditional test case block.
This patch allows SSLMutex default:logs/ssl_mutex syntax. It also
removes the mod_ssl historical '.pid' suffixes - that isn't how Apache2
specifies files.
