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.

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.

This added paragraph about optional and optional_no_ca isn't helpful.

At the TLS layer, the challenge for otpional and required are no different.

Move the caution about _no_ca up into where the option is defined
and reword.

The ap_scan_script_header_* functions were documented to be pass/fail,
but they also have a third "state" that is returned when HTTP conditions
(If-Modified-Since, etc.) aren't met. This has led to some recent bugs,
so document it.

This is a follow up of http://svn.apache.org/r1752347;
ap_meet_conditions could return a 412 status that if not
handled causes subsequent bogus reads and wrong messages
logged (like AH01070). After a chat on dev@ the feedback
was to couple HTTP_NOT_MODIFIED with HTTP_PRECONDITION_FAILED,
but any other feedback is welcome.
