Currently, 'Raw: <filename>' needs to be added to WHENCE for files that
must not be compressed. This means that such files need to be listed
twice ('File: <filename>' and 'Raw: <filename>') which is not pretty and
error prone. Also, the current implementation is broken for filenames
that contain quotes (") and it also requires grep'ing of WHENCE for every
processed line which slows things down.
Fix all of the above by introducing a new keyword 'RawFile' so that such
files are listed only once, quotes are handled correctly and grep is no
longer needed.

Any options following the compressor option --zstd or --xz are passed on
to the compressor as additional options so that - for example - the
compression level can be specified:
$ ./copy-firmware.sh --zst -19 <destdir>

When `copy-firmware` is called with `--xz` or `--zstd` it will create
broken symlinks for directories:
```
$ ./copy-firmware -v --zstd $dir
[...]
creating link qcom/LENOVO/21BX.zst -> ../sc8280xp/LENOVO/21BX.zst
```
The original target `../sc8280xp/LENOVO/21BX` is a directory. Adding the
compression extension to the directory name breaks the link. The
directory `qcom/sc8280xp/LENOVO/21BX` exists but
`qcom/sc8280xp/LENOVO/21BX.zst` does not exist.
The relative symlink needs to be resolved. If it points to a directory,
create the symlink without the compression extension.

The kernel has supported compressed firmware for quite some time. So
let's add a couple of targets to produce that. In practical terms this
means it we'll use ~5x times less space on disk.
Reportedly the amd ucode, needs to be uncompressed _within_ the
initrd in order to work. Using compressed ucode in late load just works.
Ideally this will be addressed by the initrd generators, but considering
the files are tiny in size let's skip the compression.
v2
- commit message, skip compression for files annotated as Raw
v3
- rebase

As mentioned by shellcheck backticks are considered legacy. Plus we

Properly quote, otherwise we'll get word splitting. In other words:
Files might end up installed to /some/foo/, where /some path/foo bar/ is
expected.
v2:
- rebase/split && also quote the $() output

mkdir -p creates paths that are bound to user's settings and therefore
can lead to different file mode bits of the base paths accross different
machines.
Use install instead, as this tool is not prone to such behavior.

File: entries in the WHENCE file overwrite existing files in the target
directory, however, Link: entries are skipped if the file exists in the
target directory. This can cause issues if the Link: entry is updated, but
the target directory contains an old symlink. Do not skip writing Link:
entries if the file exists, always create the symlink. This matches the
behavior of File: entries and ensures symlinks will contain values from
the WHENCE file.

Rather than require symlinks to be created in the filesystem and have
duplicate Link: entries in the WHENCE file, make copy-firmware.sh create
the symlinks on the fly.

The current make-install procedure leaves lots of garbage files that
aren't really firmware files in /lib/firmware.
Instead of copy-all-and-prune approach, copy only the listed files and
links in WHENCE by make-install for assuring only the proper firmware
files.
