parse $HTTP["remote-ip"] CIDR mask into structured data at startup
note: adds buffer_move() to configparser.y to reduce memory copying
for all config values, and is required for remote-ip to preserve the
structured data added after the config value string. (Alternatively,
could have normalized the remote-ip value after copying into dc->string)

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.)

"add support for pcre JIT"

tighten struct data_config and config_cond_info
create config key at startup and reuse for debug/trace
separate routine for configparser_parse_condition()
separate routine for configparser_parse_else_condition()
(optional addition to (data_string *), used by http_header.[ch])
extend (data_string *) instead of creating another data_* TYPE_*
(new data type would probably have (data_string *) as base class)
(might revisit choice in the future)
HTTP_HEADER_UNSPECIFIED has been removed. It was used in select
locations as an optimization to avoid looking up enum header_header_e
before checking the array, but the ordering in the array now relies
on having the id. Having the id allows for a quick check if a common
header is present or not in the htags bitmask, before checking the
array, and allows for integer comparison in the log(n) search of the
array, instead of strncasecmp().
With HTTP_HEADER_UNSPECIFIED removed, add optimization to set bit
in htags for HTTP_HEADER_OTHER when an "other" header is added,
but do not clear the bit, as there might be addtl "other" headers
new data structures and interface for processing config directives
(towards more efficient approach to config merging)
continue work to isolate data_config
provide standard types in first.h instead of base.h
provide lighttpd types in base_decls.h instead of settings.h
reduce headers exposed by headers for core data structures
do not expose <pcre.h> or <stdlib.h> in headers
move stat_cache_entry to stat_cache.h
reduce use of "server.h" and "base.h" in headers
instead of looping over all config blocks for each conditional var that
gets enabled, enable them all and run over them once.
Right now it seems we actually set all variables at once in normal
config handling (SNI only sets a subset); future modifications
might introduce new variables which are activated at a later stage
(physical path related for example).

- add new "skip" result to mark conditions that didn't actually get
evaluated to false but just skipped because the preconditions failed.
- add "local_result" for each cache entry to remember whether the
condition itself matched (not including the preconditions).
this can be reused after a cache reset if the condition itself was not
reset, but the preconditions were
- clear result of subtree (children and else-branches) when clearing a
condition cache
