Reorder and correct creation and merge of server records, optimizing
significantly for all of our null / 0 value defaults (we had always
palloc'ed, so this was very wasteful).

Corrects a segfault in 2.3.1-alpha candidate, which evaluated the
accf_map.  Due to the backwards construction of the merge (patched)
this was never initialized in virtual servers.

save an extra invocation of config files.

* configure.in: Add PCRE_CONFIG --cflags to INCLUDES; reuse AP{RU}_INCLUDES
  variables.

Add necessary search paths temporarily to CPPFLAGS.

Addition to r730717.

When switching to another header, no need to again
rename the ap_HAVE_APR_CRYPTO variable.

r730882 broke builds on MacOSX.

Now we put the PCRE libs into a new variable PCRE_LIBS
and add it to HTTPD_LDFLAGS.

That way the detected libs for PCRE could be reused in
other parts of the build system if necessary.

Side effect: I had to change the handling of HTTPD_FLAGS on
AIX and OS390 from hard setting of the variable to using
APR_ADDTO(). I hope that macro works on those platforms.

configure checks against a /usr installed OpenSSL and then link against
a different pkg-config installed OpenSSL.

(Hint: Try with Mac OS X with MacPorts's OpenSSL or FreeBSD w/OpenSSL ports.)

  any OpenSSL checks so that we don't clobber things later.

In both cases we already include SSL_LIBS, so lets add
the necessary link flags only to SSL_LIBS and not to
EXTRA_LDFLAGS.

The last of a series of changes of type
"restrict link dependencies where possible".
