Windows.  All of the Unix MPMs are working, but the others need to be

APR_EOF even though we had read valid data.  This is solved by
making cfg_getline check the buff that was returned from apr_fgets.

that lives across function calls during a single request.  Change getline() to
take a request_rec parm (rather than a conn_rec) so we can access the
core_request_config.

This is in preparation for adding look-ahead functionality to getline(), so it
can support header line folding once again.  I'm committing these changes first
so the core_request_config can be used elsewhere (i.e. ap_get_client_block).

rewrite map lookup keys and default values are now expanded
so that the lookup can depend on the requested URI etc.

Because the new code is recursive you can now write configurations
like the following (with nested map lookups) which wasn't directly
possible before -- you had to use a RewriteCond and a %N backref
instead, as in http://www.apache.org/docs/vhosts/mass.html#xtra-conf

used although I have begun to test them on my machine.  The idea behind
these buckets is that data allocated out of a pool and put into a bucket
has to survive the death of the pool until the bucket is destroyed.  To
accomplish this, we register a cleanup when we create the bucket.  If the
pool is cleared, the cleanup converts the bucket to a heap bucket and
everything is good.  If the pool isn't cleared, then we kill the cleanup
when the bucket is destroyed.

With this bucket type, all of the core buckets that were listed have been
implemented.

http_filter() uses one brigade per connection which it reads into.
As it needs to deliver buckets to the caller, they are removed from
its brigade into the caller's brigade.

they are currently storing.  There is no way we can force them to flush,
but we can advise.  This also adds the code to ap_rflush to use flush
buckets, although it isn't enabled yet.  I will enable it once we remove
buff from the code.  I also removed all calls to ap_rflush that are either
immediately before or immediately after a call to ap_finalize_protocol.
ap_finalize_protocol sends an EOS bucket, which also advises filters to
flush their data, so having both calls right next to each other is
redundant.

Unlike with my previous patch, ap_get_client_block() saves state between

Unlike with my previous patch, HTTP_IN keeps a count of remaining bytes
in the conn_rec.  Code that needs to prod it to deliver a certain amount
of request body plays with conn_rec->remain directly.
