Add in a very simple balancer "set" concept, which allows
for members to be assigned to a particular cluster set
such that members in lower-numbered sets are checked/used
before those in higher ones.
Also bundled in this are some HTML cleanups for the balancer
manager UI. Sorry for the mixins :)

* Rework inflate out filter and give it a similar workflow as the deflate out
filter. This fixes the following bugs in the inflate out filter:
- Incorrect handling of flush buckets.
- Excessive memory usage for large compressed content (because we now
already sent parts down the chain and do not process the whole brigade
first before sending something down the chain).
- Handle the case correctly where the validation bytes at the end of
the compressed data stream are distributed across different buckets /
brigades.
- Fix a memory leak due to not cleaning up the internal structures of
libz in some error cases.
* We can ignore Z_BUF_ERROR in flush_libz_buffer because:
When we call libz_func we can assume that
- avail_in is zero (due to the surrounding code that calls
flush_libz_buffer)
- avail_out is non zero due to the fact that we just emptied
the output buffer and stored it into a brigade
So the only reason for Z_BUF_ERROR is that the internal libz
buffers are now empty and thus we called libz_func one time
too often. This does not hurt. It simply says that we are done.
* Add parameter crc to flush_libz_buffer in order to call the libz's crc32
function on the output buffer if needed. This is actually needed by the
later rework of the inflate out filter.

mod_rewrite: Fix an off-by-one security problem in the ldap scheme
handling. For some RewriteRules this could lead to a pointer being
written out of bounds. Reported by Mark Dowd of McAfee.
* Remove all filters that are before the cache_out filter. This ensures
that we kick off the filter stack with our cache_out filter being the
first in the chain. This make sense because we want to restore things
in the same manner as we saved them.
There may be filters before our cache_out filter, because
1. We call ap_set_content_type during cache_select. This causes
Content-Type specific filters to be added.
2. We call the insert_filter hook. This causes filters e.g. like
the ones set with SetOutputFilter to be added.

* Remove the word SECURITY to address Joe's and Bill's concern that this would
imply that FollowSymLinks and SymLinksIfOwnerMatch are security features.
* In preparation of the changes of the inflate out filter:
- rename flush_zlib_buffer to flush_libz_buffer (this name seems
better)
- add a parameter to tell flush_libz_buffer whether it should
deflate or inflate as this function should be also used for the
inflate out filter.
* Check for symbolic links of the target file in the optimized case that we
had already done this specific directory walk for this request. This can
happen when we have an internal redirect, like the ones caused by mod_dir
(/ -> index.html). See also

Revert r422298, because it introduces GNU Make specific extensions to the Makefile, and should be replaced by doing the work inside configure, instead of the Makefile.in.
* Fix potential memory leaks in deflate_out_filter if bailing out due to an
error (either in the lower filter chain or during a libz operation). We need
to call deflateEnd as it is very likely that this filter is never called
again to ensures that libz's internal structures get cleaned properly.
* Fix wrong FLUSH bucket handling in deflate_out_filter: Actually the internal
structures of libz never got flushed as ctx->stream.avail_in is always zero
here. As the EOS and the FLUSH bucket case use the same code for flushing
libz's internal buffers move this code to the new function flush_zlib_buffer.

Restructure the find_route_worker() function. Basically,
it should take care of knowing about usable and unusable
