Thread saftey lock for mod_rewrite's cache... I'm sure others will have
  some 'better ideas' but this will work for now.

  Simplified mod_env's directives to behave as most directives are
  expected, in that UnsetEnv will not unset a SetEnv and PassEnv
  directive following that UnsetEnv within the same container.
  Also provides a runtime startup warning if a PassEnv configured
  environment value is undefined.

  Fix a nasty GP fault... stop testing buckets after they are passed!!!

  Restrict by content type and encoding before we go and try to drag in some
  text to merge as headers and footers to autoindex pages.  This will escape
  index.gif from a bold attempt to use IndexHeader index ;)

  Also pass in the args to the subrequest, for anyone trying to decode what
  the user is looking at.  A great example of this coming up.

  Canonicalize all absolute <Directory > sections, not simply those that
  fail to end in a '/'.  Slash test is afterwords, once we've canonicalized
  any '\' and other aliases to '/'.

We need to allocate storage space for the terminating NULL AND the extra /
we may tack on to the string at some point.

How in the hell the stars were aligned for this to corrupt newv via the
strcat at line 580 is unknown.

Resolves segfault seen on daedalus.

  ap_run_child_init is not an optional function ;)

  Consistify a variable name with the rest of httpd

the proc_mutex header for the sake of consistency.

uses native APR types for thread mutexes, cross-process mutexes,
and condition variables. Who's next?

here to set permissions on SysV Semaphores. MPMs will be modified to
call this new function as they are ported to the new APR lock API.

This was preventing the MaxRequestsPerChild config directive from working
properly.

Handle MaxRequestsPerChild a bit more sanely.  When MaxRequestsPerChild is hit,
the child signals an event that causes the main child thread to signal the parent
to restart.

We're now waiting for it to be discarded or we need to bump the tag on
server/core.c.  And, we need to fix the proc_wait thing to someone's
satisfaction.

appropriate links to the Listen directive.

If I had known that so many files had the Port directive in it, I would
have bundled this up as one big commit.  *sigh*  I just kept looking
and finding new files, fixing, and committing.  So, this should be the
rest of them for now.

  Listen to my own advise.  Fortunately, the new apr_pool_readonly code
  catches these in no time ;)

by autoconf and then placed in the builddir, not the srcdir (which we
didn't notice until we tried to do VPATH). When cpp couldn't find apr.h
we would decide not to build mod_so, which is kinda bad.

Now we include both paths when we test for APR_HAS_DSO and everyone is happy.
