mod_http2: fail requests without ERROR log in case we need to read interim

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.
