Roll forward fixes identified for 1.3.13-dev.

  Note... this module still needs more control over async emulation, etc.

  Completed review for new tests:
    APR_STATUS_IS_EACCES(s)
    APR_STATUS_IS_EEXIST(s)
    APR_STATUS_IS_ENAMETOOLONG(s)
    APR_STATUS_IS_ENOENT(s)

  Where the old EACCES et. al. still exist, we have a problem (not yet
  using APR at all)

  More to come...

  Here it is, the Win32 part of the big canonical errors patch.

  The reason is really, really simple.  If we ever choose to mix clib and
  dos error codes, they criss-cross and don't line up, but they share the
  same number space.  As I wrote the new APR_IS_ERROR macros, I realized
  we were about to shoot ourselves in the foot.

  These changes nearly entirely affect Win32 only.  The next big patch will
  affect all of the rv == APR_ENOENT type problems throughout the system.

is that the bucket code does not respect the length passed into it.  This
is correct for buckets, but it means that when we get data out of the
buckets, we may have to split the bucket to make sure that any copy
operations are safe.  We were originally doing the split at the number of
characters read from the bucket, but we really want to do it at the length
of the buffer.

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

1) separate filter lists hanging off the r and the c

   requests start off with the same filter list as the connection

   the input filter list is not initialized for subrequests

   internal redirects start off with the same filter list as the
   connection

2) AddInputFilter directive (blatant rip-off of Ryan's AddOutputFilter
   directive); as with AddOutputFilter, the network is implicitly to the
   right of the specified filter list; this may not be the most
   intuitive way to specify the filters; not sure yet

Build process:

  -add datadir and localstatedir substitutions
  -fix layout name
  -fix logfilename misspelling
  -fix evaluation of installation dir variables and
  -replace $foobar by $(foobar) to be usefull in the makefile

Cross compile:

  -add rules for cross-compiling in rules.mk. Okay, rule to check for
   $CC_FOR_BUILD is still missing
  -use CHECK_TOOL instead of CHECK_PROG for ranlib
  -add missing "AR=@AR@" to severaly Makefile.in's
  -cache result for "struct rlimit"
  -compile all helper programs with native and cross compiler
   and use the native version to generate header file

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.

writev_it_all() in case we have another brigade to process.
Otherwise, nbytes is bogus for the second brigade and
writev_it_all() doesn't know when to quit (it loops).

In writev_it_all(), when compensating for bytes already sent
don't go beyond the number of iovs we were passed on input.

1) don't compute md5 if we have a content filter; it is almost always wrong
2) add note about adding md5 filter in the future; this can be done
3) delete some APACHE_XLATE/CHARSET_EBCDIC baggage associated with md5
   digest support; part of this deleted baggage is a segfault on
   subrequests referencing r->rrx (which is not allocated for subrequests)

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 *.
