Introduces the syntax "%{:<word>:}", borrowed from the <var>'s one, and which
likewise can be embedded anywhere in a string expression (the same reserved
character ':' gets reused in an unambiguous manner).
This allows the two types of expressions (boolean and string) to now share
fully the same language set, namely: strings, lists, vars, regexes, backrefs,
functions with multiple or complex arguments, and especially combinations
thereof.
Most of them were reserved to boolean expressions only, while complex string
constructions can also benefit to, well, strings. The <word> construct allows
that (say the syntax "%{:<word>:}" looks like a temporary variable constructed
in a string).
Since string expressions may now have to deal with lists (arrays), they also
need a way to produce/extract strings from list and vice versa. This can be
done with the new "join" and "split" operators, while the new substitution
regexes (like "s/<pattern>/<substitute>/<flags>") may be used to manipulate
strings in place. All this of course available for both string and boolean
expressions.

ovector will be created to accept greater than nmatch elements for processing.
Allocate enough elts in all circumstances for pcre2api.

This patch removes the needless assignment of re_erroffset in the conf pool
by the worker threads; such mistakes break the shared copy-on-write pages of
memory that should have remained common between all httpd worker processes.
Two de-optimizations are inherent in this patch, the former ovector-on-stack
opportunity is lost unless implemented as a new general context. Safer that
we either create a new general context using pool allocation, or recycle a
per pool or per thread match_data buffer of some arbitrary 10 elts or so.

PCRE dropped support for pcre_info() which is
deprecated since a long time. Use pcre_fullinfo()
instead, which exists since version 3.0 of PCRE.

NEVER NEVER screw around with redeclaring AP_ macros and constants.
If the compiler won't pick them up, e.g., AP_DECLARE, ya've done
something wrong from the start.
All httpd/ap headers depend on httpd.h - plain and simple, so this
un-convolutes the unusual order here.
STATIC has become PCRE_STATIC, along with some other odd definitions.
The only remaining emit is that _pcre_free export is imported, which
implies something is unusual with the declaration. Still researching.

regoff_t typedef with int; s/size_t/apr_size_t/;. Comment fixes.
* server/util_pcre.c: s/size_t/apr_size_t/.
* include/httpd.h: Include stdlib.h here instead since many other
files assume it was included by httpd.h at some point.

internalise the ap_reg*<->PCRE wrapper:
* configure.in: Add srclib/pcre to the include path.
* include/ap_regex.h: Renamed from include/pcreposix.h. Prefix all
constants with AP_; prefix all functions and types with ap_. Define
AP_DECLARE to nothing if necessary. Remove regcomp error codes.
* include/httpd.h: Include ap_regex.h not pcreposix.h.
(ap_pregcomp, ap_regexec, ap_regfree): s/regex_t/ap_regex_t/.
(ap_regexec, ap_regerror): Prototypes moved to ap_regex.h.
* server/util.c (regex_cleanup, ap_pregcomp, ap_pregsub, ap_pregfree):
Adjust for ap_ prefixed types. (ap_regexec, ap_regerror): Removed.
* server/Makefile.in: Build util_pcre.c.
* server/util_pcre.c: Copied from srclib/pcre/pcreposix.c; remove use
of PCRE-internals to do error mapping; rename types to add AP_/ap_
prefixes as above. Use APR includes. (ap_regerror): Use apr_snprintf.
* srclib/pcre/Makefile.in: Don't build pcreposix.c into libpcre.la.
* modules/*: Update to use new type and constant names.
