* mod_access_compat, mod_authz_host: Handle '#' character.
For mod_access_compat, disable '#' in hostname completely.
For mod_authz_host, treat '#' as a comment and ignore everything after that.
This allows better handling of admin errors like
'Require host localhost# Add example.com later'.

* modules/aaa/mod_authz_host.c (host_check_authorization): Simplify
  comment stripping in "Require host"; log a warning if a comment is
  used in 'Require host', or an error if the expression is empty with
  the comment stripped. (Currently in 2.4, #comment part is parsed)

  (doRotate): When exploding the time for strtfime formatting, iff in
  -l mode, subtract the offset and explode the real Unix time as a
  local time so %Z etc works correctly.

  Switch from int to long to fix an unnecessary Y2K38 issue.  Adjust

  +1: elukey, jim, ylavic
  elukey: this patch has been requested a couple of times in the users@ mailing list,
          but from my tests in trunk the async/set-aside core features would already
          do the job without the need of this patch. I am proposing the backport
          to allow more users to migrate away from mod_fastcgi.

mod_proxy_fcgi: Add the support for mod_proxy's
                flushpackets and flushwait params

This change was requested on the development mailing
list in order to fill another gap between mod_fcgi
and mod_proxy_fcgi, namely the -flush funtionality.

The more evolved core trunk code would not need this
feature becuse of the non-blocking writes, but it
is be needed in 2.4.x.


mod_proxy_fcgi: limit the flush buckets inserted when flushpackets=on|auto

This commit is a follow up of r1802040 based on Jacob's
feedback, namely inserting the FLUSH buckets only when
really needed and useful, not always.


mod_proxy_fcgi: follow up to r1807876.
Fix mixed declarations and code [-Wdeclaration-after-statement].

Fix a compilation warning introduced by r1802040.
mod_proxy_fcgi.c:893:19: warning: ‘flushpoll’ may be used uninitialized in this function [-Wmaybe-uninitialized]

This warning is a false positive.


mod_proxy_fcgi: prioritize the check for mayflush when using flushpackets

The mayflush variable should be checked before the rest
to avoid polling when not needed.

Suggested by Yann Ylavic on the dev@ mailing list.

Propose backportable fix to accept libxml2 path in the
base form or the absolute path to include tree form.

Nowhere does the --with-libxml2= arg suggest the path
is that of the include tree, and disagrees with httpd's
use of --with- syntax for package location.
