* 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.

  I don't hit any segfaults with yesterday's HEAD and APR_POOL_DEBUG defined

  I don't hit any segfaults with current HEAD and APR_POOL_DEBUG *not defined*

  I do hit segfaults down in apr_pool debug code with current HEAD and
  APR_POOL_DEBUG *defined*

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.

Until Win32 and OS/2 have the function added this will break their

the patch to apr to go in :)  Go Will!

The per-transaction pools in the worker MPM can't be children of

while some workers are still procesing requests using the transaction

  just to compile ourselves.
