* feat: add tr_strbuf class for building tmp strings
Based on fmt::basic_memory_buf, this is a growable string buffer that
has an initial size that's large enough to build most filenames or URLs
without needing heap allocations.
Adds a couple of extra helpers such as a `c_str()` method to make dealing
with old zero-terminated string APIs easier.
network.target does not guarantee interfaces are fully configured, which
can result in bound addresses not being available when the daemon
starts. This leads to errors on start-up and potentially broken
connectivity.
network-online.target does provide these guarantees, but needs a
slightly different dependency configuration with Wants= on top of After=
(cf. systemd.special(7)).
Closes#2720.
ProtectSystem mounts /boot, /efi and /usr as read only, basically
disallowing the daemon from ever writing there. PrivateTmp sets up a
file system namespace for /tmp and /var/tmp/ basically hiding it from
other processes.

Attempts to create memory mappings that are writable and executable at the same time, or to change existing memory mappings to become executable, or mapping shared memory segments as executable are prohibited.
There's no reason transmission should be doing that. If it does, it's because of malicious code exploiting a vulnerability.

* refactor: [[maybe_unused]] iff arg _might_ be used
If the arg is never used, comment out its name.
If the arg is _sometimes_ used e.g. with ifdefs, use [[maybe_unused]].

* refactor: const correctness
* refactor: use getpwuid_r instead of getpwuid
* chore: simplify dict walking loop logic
* refactor: remove dead store assignment in announcer
* refactor: use std::make_shared
* Support .git files (e.g. for worktrees, submodules)
* Fix symlinks in source tarball, switch to TXZ, adjust non-release name
* Remove autotools stuff
Since there is no way to mark parameters as [potentially] unused in
standard C and when using MSVC compiler, use the widely accepted
cast-to-void approach instead.
