TODO:
* IMHO the topic ToC3 should be deleted completely.
* All references to "patch Apache" or "EAPI patch" should be removed
* A native english speaker might want to proof-read the doc and polish it

- avoid creating a new bucket brigade for each EOS or FLUSH bucket
- do not pass FLUSH bucket since BIO_bucket_flush() already does so
  if there is any data to flush.
- do not call apr_brigade_destroy(bb); since we will have either
  emptied it or passed it, in which case it will be destroyed further
  down the chain.

* eliminate the get_pathname and free_file vtable functions. add the
    deliver() function to have the provider deliver the content
    straight into a filter [stack].

* eliminate readable streams -- they are now obsolete. this gets rid
    of the read_stream vtable function and DAV_MODE_READ*

* implement a deliver() function for the FS provider. this simply
    constructs a bucket and EOS and shoves them into the filter. note
    that this is debug code only, so the "large file" issue handled by
    the core's default handler doesn't count here.

* allow the provider to handle GET for any resource type and for
    collections. this moves the checks into the provider.

Reduced the initial size of the r->headers_in and r->subprocess_env
tables...this saves us 600 bytes per request, which (based on tests
I just ran) helps keep r->pool from overflowing its initial 8KB
allocation and having to alloc another 8KB block.

code.  Now that the code no longer allocs huge buffers (based on the
last commit), there's no need to incur the overhead of creating a
temporary pool just to clean up the storage quickly.  This saves
a lot of space (because the temp pool used 8KB) and a small amount
of processing time.

As a side-effect of this change, we don't need the gotos any longer.

we don't supply a bogus socket to the caller if the accept fails.
(This was causing problems in the worker MPM, which tried to process
the returned socket if it was non-NULL, even if unixd_accept()
returned an error.)

to avoid segfaults.

Using prefork MPM and APR_POOL_DEBUG and ElectricFence, I found a
couple of paths where weren't able to report APR_EOF all the way
back up the call tree, leading us back into core_input_filter with
an empty brigade.

Some of the paths in core_input_filter handled it, some didn't.
