The OS/390 compile options are hard-coded because we need the
special DLL,EXPORTALL on *all* object files that are part of the
core so that dsos can reference symbols in the core.  (Of course,
we use the option on more object files than that, but it doesn't
seem to hurt anything.)

We hard-code the enablement of DSOs on OS/390 because the
library functions on OS/390 to manage explicit loading are not
portable, so there seems to be no use in probing for them.

1)  don't put the trailing 0\r\n\r\n in lenstr; that buffer is
    already in use (pointed to by another transient bucket); using
    lenstr again overlays that other chunk header
2)  insert the bucket with the trailing "0\r\n\r\n" *before* the eos bucket

be enabled and disabled on a per-server basis.  This patch makes it use
a flag

bug fix in chunk_filter(): it was creating the wrong-size bucket.

chunking now appears to be working (without using BUFF).

bucket brigades are sent to this filter, it inserts the chunking header
at the front of the brigade.  When the filter sees an EOS bucket, it
adds the 0 chunking trailer.

to the filter stack.  This makes the chunking filter work.  Without this,
the core_filter is installed in the insert_filters hook, when we get
to the ap_send_http_headers function, we insert the chunking filter, but
it has been installed after the core_filter.  This means the chunk_filter
is never called.

This reverses this.  The core_filter is installed in the insert_filters
hook, and we put the chunk_filter in during ap_send_http_headers.  This
time, the chunking filter is installed before the core_filter, and it
gets called correctly.

    insert filters properly (by stopping the scan before transitioning to
    the parent request's filters)

	Make compilable on Windows again.  I'm not sure the x = { [1] = 1 }
	syntax is even ANSI C, but it originally compiled for me.  Oh, well.
	I'd rather have this statically built at compile time, but I don't
	want to add the dependencies on the method order and its being
	a contiguous sequence.
