mod_substitute: use local/native LF for splitting

On platforms where the APR_ASCII_LF != '\n', like EBCDIC systems,
strmatch or pcre patterns from the source or config will be in
the native encoding, and this module will really only work on 
content in the native encoding.

(mod_substitute runs before mod_charset_lite for a similar reason)

I thought #if APR_CHARSET_EBCDIC or even #ifdef __MVS__ was overkill
here. 



(CTR due to ebcdic-only)

Save a few bytes in the conf pool.

'push_item' and 'add_alt' already duplicate their parameters, so we can safely use the temp_pool here.

Use 'ap_cstr_casecmp' to simplify code.

Remove useless case. We know that to can not be NULL at this point.

Follow up to r1772812: update APLOGNO().

* modules/ssl/ssl_engine_kernel.c: Constify the ssl_hook_Fixup_vars array itself.


winnt/service: each log message should use its own APLOGNO.

PR61009: be as helpful as possible during -V operation

A configtest isn't useful if you're just trying to get compile settings.
Move the settings dump up to just after ap_read_config(), which has
already done the minimum necessary to figure out which MPM is in use.

Even if ap_read_config() failed, still print as many compile settings as
we can. The user will see the error log entry on stderr.

mod_brotli: Unbreak building other filter modules without libbrotlienc.

Don't add -lbrotlienc to the MOD_LDFLAGS unconditionally.  And, when
adding it, use MOD_BROTLI_LDADD to avoid linking all filter modules
against this library.


mod_brotli: Rewrite the autoconf script in a, hopefully, less convoluted way.

Explicitly handle different cases when we do a pkg-config lookup
(<nothing>, --with-brotli or --with-brotli=yes) or examine the path
provided by the user (--with-brotli=PATH).

This lays the groundwork to simplify the switch to the official Brotli
library (https://github.com/google/brotli), instead of expecting the
install layout of a third-party wrapper (https://github.com/bagder/libbrotli).


mod_brotli: Update makefiles to use the library layout of the official
Brotli repository.

With the recent update (https://github.com/google/brotli/pull/464), the
official repository now produces pkg-config metadata files (brotli.pc),
and has a fixed library layout (libbrotlicommon/libbrotlienc/libbrotlidec)
on both Windows and Linux.  Expect this layout in the makefiles, and take
advantage of the pkg-config metadata, if it's available.


mod_brotli: Update makefile to cope with the pkg-config layout change
in https://github.com/google/brotli/commit/fe9f9a9

There's a typo in the upstream commit [1] (s/brotlicommon/libbrotlicommon)
that currently produces an unusable libbrotlienc.pc file, but hopefully
this is going to be fixed there.
