MPEG::File::isSupported() scans for frame sync bytes that can appear
in other files, causing them to be misidentified as MP3.
This also includes a test with such a file.
* Add Shorten (SHN) support
* Add `<cmath>` include and use `std::log2`
* Use `uintptr_t` for buffer size calculations
* Work around `byteSwap` not using fixed width types
* Remove four-character codes
* Attempt to fix `static_assert`
* Revert previous commit
* Update `read_uint`* functions
* Use ByteVector for byte swaps
* Use different ByteVector ctor
* Rework variable-length input to use ByteVector
* Rename some variables
* Naming and formatting cleanup
* Add basic Shorten tests
* Rename a constant
* Rename `internalFileType` to `fileType`
* Add documentation on `fileType` meaning
* Add DO_NOT_DOCUMENT guard
* Fix shadowVariable issues reported by cppcheck
cppcheck --enable=all --inline-suppr \
--suppress=noExplicitConstructor --suppress=unusedFunction \
--suppress=missingIncludeSystem --project=compile_commands.json
* Formatting cleanup
* More explicit types
Reason for these changes: getRiceGolombCode(k, uInt32CodeSize) was
called with int k for uint32_t& argument.
There was also a warning from MSVC for line 299:
warning C4267: 'argument': conversion from 'size_t' to 'int'
* Additional explicit types
* Rename `SHN` namespace to `Shorten`
Also rename files to match

With specially crafted WAV files having the "id3 " chunk as the
only valid chunk, when trying to write the tags, the existing
"id3 " chunk is removed, and then vector::front() is called on
the now empty chunks vector.
Now it is checked if the vector is empty to avoid the crash.
Detect ADTS MPEG header to use it also for AAC.
The test file empty1s.aac was generated using
ffmpeg -f lavfi -i anullsrc=r=11025:cl=mono -t 1 -acodec aac empty1s.aac

There are m4a files with regular (non-full) meta atoms. When such
a meta atom is not correctly parsed, the subsequent atoms are not
recognized and offsets will not be adjusted when atoms are added,
which will corrupt the MP4 file.
This change will look behind the meta atom to check if the next
atom follows directly, i.e. without the four bytes with version
and flags as they exist in full atoms. In such a case, these
four bytes will not be skipped.
Witnesses of this strange format specification are

* Add DSF and DSDIFF file types management
* Fixes for some build chains
* unit64_t replaced by unsigned long long, warning fixes
* Remove C++11 extension incompatible with some build chains (enumeration in a nested name specifier)
* Change typedef types (uint, ulong, ...) to standard types
remove BUILD_FRAMEWORK changes from this pull request
* Replace deprecated String::null and ByteVector::null by String() and ByteVector()
Styling update, thanks to FestusHagen
* Restyling
* Restyling to reduce length of excessively long lines
* Add to detectByExtension
* Added `isSupported(IOStream *stream)` to `DSF::File` and `DSDIFF::File`
The file name unsupported-extension.xxx causes issue when unpacked
taglib-xxx.gz over an NFS partition. The file extension ".xxx" is the
one NFS uses for its own purpose and hence it will not allow creation
of this file.
Hence renamed the file and modified the test cases that checks for this
file.
