[core] use stack w/ pcre_exec unless save captures

use stack w/ pcre_exec unless saving captures from config conditions

reduce memory allocations per request where lighttpd.conf does not
contain url.redirect or url.rewrite rules where replacements reference
a match of the enclosing lighttpd.conf condition (e.g. %0, %1, %2 ...)

move cond_cache_t 'patterncount' to cond_match_t 'captures'
While cond_match_t is no longer sized power-2, it is generally expected
to be used much less frequently than before (which was all the time),
since it is now used only with url.redirect or url.rewrite with
references %0, %1, %2, ...

[core] save config regex captures only if used

save config regex captures separately only if used by url.redirect

(or for conditions containing directives from any other module
which calls config_capture() for its directives during init)

keep pointer to match data (cond_match_t *) in r->cond_match[]
rather than cond_match_t to reduce data copying in h2_init_stream().
h2_init_stream() copies the results for already-evaluated conditions
to avoid re-evaluating connection-level conditions for each and every
stream. When conditions are reset, then the pointer in r->cond_match[]
is updated when the condition is re-evaluated. (This all assumes that
HTTP/2 connection-level conditions are not unset or re-evaluated once
HTTP/2 streams begin.)

[multiple] PCRE w/ PCRE_STUDY_JIT_COMPILE (fixes #2361)

enabled by default
disable using server.feature-flags += ("server.pcre_jit" => "disable")

Available since pcre-8.20 (2011), and improved in pcre-8.32 (2012),
PCRE_STUDY_JIT_COMPILE can greatly speed up repeated execution of PCRE
patterns. (https://zherczeg.github.io/sljit/pcre.html)

lighttpd continues to use pcre_exec() instead of pcre_jit_exec(),
even though doing so does not realize all of the performance increase
potentially available with PCRE_STUDY_JIT_COMPILE and pcre_jit_exec().

pcre_jit_exec() is available with PCRE 8.32 and later, if PCRE is
compiled with --enable-jit, but lighttpd does not currently use
pcre_jit_exec() since the PCRE library might not have been compiled
with --enable-jit (though this could be solved with a weak symbol).
Similarly, lighttpd does not currently configure the pcre_jit_stack.

(Using pcre_jit_exec() may be revisited in the future.)

Note: *not applied* to CONNECT method

Note: In a future release, URL normalization likely enabled by default
(normalize URL, reject control chars, remove . and .. path segments)
To prepare for this change, lighttpd.conf configurations should
explicitly select desired behavior by enabling or disabling:
server.http-parseopts = ( "url-normalize" => "enable", ... )
server.http-parseopts = ( "url-normalize" => "disable" )
