  are lots more to fix, these are the obvious ones that already did proper

request_rec.  This means that a conn_rec must be supplied when calling
ap_add_filter.  The reason for this change is that we need to be able to
add the core_filter (whether or SSL or not) before we try to read the
request.  This way, if a request fails, we can actually send the error
page back to the client.  With this change, we add the core filter to the
conn_rec during the pre-connection phase.

Otherwise, nbytes is bogus for the second brigade and

instead of the number of bytes sent.

default_handler() ignores the ap_send_fd() return code, but
mod_file_cache doesn't.  When mod_file_cache's handler called
ap_send_fd(), the client would get the desired file plus an
error document (500 internal server error), which was delivered
because mod_file_cache's handler returned an error since
ap_send_fd() returned non-zero.

Also in this commit is a hack to be able to compile when APACHE_XLATE
is defined.

FIN/EOF or error.  This meshes with what getline() looks for.  It isn't
perfect, but it avoids some nasty loops consuming all available storage
on http/1.1 connections.  In keepalive state, we call getline to read the
next request...  getline() calls core_input_filter() (indirectly)...
core_input_filter() calls apr_recv() which returns APR_SUCCESS/0 bytes
to signal FIN/EOF.  But core_input_filter() returned a bucket with length
zero to getline(), so getline() called core_input_filter() again.

ap_os_case_canonical_filename() interface: It returns const char * on
platforms where no mapping is ever performed but char * on platforms
where mapping can occur.  Such a discrepancy seems to be a good choice,
as no platform is penalized with extra pathlength.

This tweak gets rid of a const misuse warning on systems where
ap_os_case_canonical_filename() returns const char *.

  Forward port 1.3 overhaul of isapi to 2.0.

  Yes - it's blatently obvious that this should be 'bucketized', but the
  sequence I will follow is:

    *) compatibility of sources
    *) extension to async + transmitfile emulated support
    *) localization of ISAPI* directives to Directory, File blocks
    *) addition of ISAPI caching
    *) recode for buckets.

  I'm actually looking forward to the mod_cgi bucketization as a model.
