applied to 2.4.x.

These are the mod_brotli related Makefile changes that didn't make it
into the original backport proposal merged in r1791231.  The lack of these
changes causes a failing Unix build in my environment if mod_brotli is not
being built.  Another issue is that by default the CMakeLists.txt file
refers to invalid library filenames.

Shortlog of the changes:

    r1761824: Unbreak building other filter modules without libbrotlienc.

    r1771789: Rewrite the autoconf script in a, hopefully, less convoluted way.
    This lays the groundwork to simplify the switch to the official Brotli
    library.

    r1771827: Update makefiles to use the library layout of the official
    Brotli repository.

    r1779111: Update makefile to cope with the pkg-config layout change
    in https://github.com/google/brotli/commit/fe9f9a9

A better comparison would be total number of documents in-sync, or some

mod_brotli: Add initial implementation.

This new module supports dynamic Brotli (RFC 7932) compression.  Existing
mod_deflate installations can benefit from better compression ratio by
sending Brotli-compressed data to the clients that support it:

    SetOutputFilter BROTLI_COMPRESS;DEFLATE

The module features zero-copy processing, which is only possible with the
new API from the upcoming 1.0.x series of brotli [1].  The Linux makefile
works against libbrotli [2], as currently the core brotli repository doesn't
offer a way to build a library [3].  Apart from that, only the CMake build
is now supported.

[1] https://github.com/google/brotli
[2] https://github.com/bagder/libbrotli
[3] https://github.com/google/brotli/pull/332


mod_brotli: Allow compression ratio logging with new BrotliFilterNote
directive.


mod_brotli: Handle new 'no-brotli' internal environment variable that
disables Brotli compression for a particular request.

This mimicks how mod_deflate handles the 'no-gzip' env variable, and
should allow seamless migration for configurations that use it.


mod_brotli: Explicitly cast 'const uint8_t *' to 'const char *' when using
the data received from Brotli to create a bucket.

This fixes a /W4 warning in my environment, and should also allow building
mod_brotli on NetWare.

unused variable error could mistakenly note that brotli isn't available.

mod_brotli: Update makefile to allow using Brotli library >= 0.6.0.

The 0.6.0 version has just been released [1], and it contains the
necessary API required for mod_brotli.

mod_brotli: Fix a minor typo in the description of BrotliAlterETag
that has been referring to httpd 2.2.x.

There's no mod_brotli in 2.2.x.

mod_brotli: Comment on the default choice (0) for BROTLI_PARAM_LGBLOCK.
