Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
as well as a comment arg to the add, adduser and update cmds.
update allows the user to clear or preserve pw/groups/comment.

If a bucket is split at the first or last character, then we should get
a zero length bucket and a bucket containing the original text. Later
filters will either throw away the zero length bucket, or they will just
ignore it. The problem is that if we return an error in those conditions,
then all filters need special logic whenever they are going to split a
bucket. By always splitting, only a few selected buckets need the special
logic to deal with zero-length buckets. This also fixes mod_include to not
have the special logic around it's split call.

This commit adds support for purely name-based virtual hosting that

identical httpd.conf files on all the machines in a load-balanced

Modify the way filters are added to the server. Instead of using a FIFO,
we use a modified LIFO. It is modified, because if we add a filter while
in the middle of another filter, the added filter gets put in after the
current filter. This requires that the server is smart about which filters
are added when. This should be handled by the HTTP protocol, but we will

This change is necessary, because currently when we add a filter it goes
after the last filter of the same type. This is broken whenever we want
to add a filter that has a dependancy. Think about the core and chunking
filters. They are of the same type, and core is always added first. When
