flac dev - Sep 2022 - 1.4.0 release candidate

Hi all,

Current git state (last commit fuzzer: Do not add corrupt vorbiscomment
metadata block, 5d1402e) can be considered a release candidate for FLAC
1.4.0. I do have plans to restructure (and remove most of) the
documentation (see https://github.com/xiph/flac/pull/411), update the
changelog, the version number, release date and AUTHORS file, but plan no
more changes to the actual code except when something comes up.

I invite anyone interested to build from git, run the test suite and report
back any problems. Comparisons of compression and speed between current git
and 1.3.4 are also welcome.

Kind regards, Martijn van Beurden

Here are results I have

**github CI**
- x86_64 all combinations of Ubuntu/MacOS, GCC/Clang, autotools/CMake,
32-bit words/64-bit words
- x86_64 Windows CMake build static and shared
- x86_64 Ubuntu distcheck
are all fine

**travis CI**
- Aarch64 GCC+Autotools, GCC+CMake, GCC+CMake+64bitwords, GCC+CMake+noasm
- PPC64 GCC+Autotools, GCC+CMake, Clang+CMake, GCC+CMake+64bitwords,
GCC+CMake+noasm
are all fine

**oss-fuzz**
- Only timeouts reported, no aborts or problems with address sanitizer,
undefined sanitizer or memory sanitizer

**Own systems**
- x86_64 Ubuntu all combinations of GCC/Clang, Autotools/CMake,
shared/static, exhaustive tests with Autotools
- x86_64 Ubuntu GCC+Autotools, integer only and no asm optimizations
- Aarch64 Debian all combinations of GCC/Clang, Autotools/CMake,
shared/static, exhaustive tests with Autotools
- ARMv7 Debian GCC+Autotools and GCC+CMake, shared/static
- ARMv6 Debian GCC+Autotools, shared/static
are all fine

For x86_64 MinGW I tested all combinations of GCC/Clang, Autotools/CMake,
shared/static but had some problems here with the shared builds.
-DFLAC__NO_DLL is added to the Makefile to make sure test_libFLAC builds
with the static library only. Also, it seems the libtool wrapper executable
is not able to properly handle UTF-8 characters. When circumventing this by
placing the executable and library in the same directory (thus not needing
the wrapper to run the tests) the tests pass.
