Some upstream systemd units are conditionally installed into the systemd
output, so we must make sure the feature that enables their installation
is enabled on our side prior to trying to use them.
Like for matrix-whatsapp use a static user so that the registration file can be automatically shared with synapse.
This also includes the registerToSynapse config option.
The option has been added in 50029ed89c
but never had any effect. As far as I could tell, it was only added for
backward compatibility. I think it's safe to remove this after 3+ years.
I opted for removal instead of implementing it since the module will
just do nothing if no site is configure, thus no enable / disable switch
is needed. Especially on a per-site level.
The seekable format splits compressed data into a series of independent
frames, each of which can be decompressed individually. This allows to
distribute images in smaller chunks and allows image downloads to be
paused and resumed later from the same point.
Seekable archives as a whole can be decompressed with any regular zstd
decompressor. However, partial decompression requires to know the
starting position of the desired frame, which can be extracted from a
skippable frame (aka seektable) that is appended to the compressed data.
