Cleanup more of the Apache configuration. This removes all of the shared
memory checks, because Apache relies completely on APR for shared memory
support. In doing this, we also need to know how APR/MM are providing
our shared memory (ie file or memory) that requires the change made to
APR's configure script that was just committed.

Remove a bunch of string functions from Apache. These are basically
standard string functions like strstr, strcasecmp, etc that Apache used
to define for platforms that don't have them. These functions and the
feature tests have moved down to APR where they really belong. In doing
this, I am also able to remove a bunch of tests from the Apache configure

Fix zombie process problem with mod_cgi. This problem was introduced
as part of the "Convert ap_proc_t to a complete type." enhancement.
mod_cgi previously declared a ptr to an ap_proc_t, storage was allocated
by ap_create_process() from the request pool, and the ap_proc_t address
was passed to ap_note_subprocess().
With the "Convert ap_proc_t to a complete type." change, ap_proc_t
lived in autodata, but the address was still passed to
ap_note_subprocess(). When the pool was cleaned up, the ap_proc_t
in autodata had been used for something else, so the contents were
garbage, but pool cleanup needed the contents, especially the os
pid to pass to waidpid(). Since this was garbage, we never reaped
status from the cgi child and thus the cgi child remained a zombie.

Make a copy of getenv("PATH") before storing for later use. Some

CGIs on OS/390 had a bad PATH due to this. (Believe it or not, ANSI

Some similar getenv() usage was left alone as it was specific to a
certain platform, and I assume that getenv() doesn't have the "issue"

Add server tokens back to 2.0. Also bring forward the change to allow
the PRODUCT_ONLY value for ServerTokens. This is relatively clean,
all of the code lives in http_core, and when a module wants to add a token,
they just call ap_add_version_component from the post_config hook. Actually
ap_add_version_component can be done anytime after the config has been
parsed, it just makes the most sense to do it in post_config IMHO.

APACHE_XLATE, when doing translation that isn't single-byte-only
We must zap the Content-length header (if any). Otherwise, the
browser will be seriously confused :) The header is zapped in
ap_set_keepalive() right before we look for Content-length, transfer
encoding, HTTP level, etc. to decide, among other issues, whether or
not to turn on chunked encoding. For HTTP 1.1, if we don't send
Content-length, we need to use chunked encoding, so we have to zap
the header before that decision.
Interestingly, in Russian Apache the Content-length header is
zapped after ap_set_keepalive() is called, so with HTTP 1.1 they
break the content-length-or-chunked rule.

When ErrorDocument specifies a redirection, we don't get here.
When the error response is headers only, we don't need to set

ap_send_error_response() should be handled now.
