The struct turned out not necessary during initial implementation but was not unwrapped into its single string field. This change replaces it with the underlying string and removes the indirection.

This no longer exposes the pipewire socket to the container, and instead mediates access via pipewire-pulse. This makes insecure parts of the protocol inaccessible as explained in the doc comment in hst.
Closes #29.

This is for setting up the pipewire-pulse container in shim, for #29.

This is a private work directory owned by the specific shim. Useful for sockets owned by this instance of the shim and requires no direct assistance from the priv-side process.

This fully replaces PulseAudio with PipeWire and enforces the PulseAudio check and error message. The pipewire-pulse daemon is handled in the NixOS module.
Closes #26.

This is slightly counterintuitive, but it turned out well under this framework since the daemon backs its target file.

This is very simple and takes almost no inputs. This is not yet hooked up to anything to prevent breaking any existing behaviour.

These are for #26. None of them are implemented yet. This fixes up test cases for the change to happen. Existing source code and JSON configuration continue to have the same effect. Existing flags get its EPulse bit replaced by EPipeWire.

This significantly increases readability. This patch is pretty big so it is being done after mostly everything has settled.

Clang is better than gcc in various ways. This also pulls in clang-format which is very helpful.

The "main.go" name is quite confusing as this is often only present in main packages.

This is mounted for the default read-only /dev/ when programs want to use shm_open(3). Defining it here is less error-prone and saves the extra append at runtime.

This is cleaner and makes more sense. The longer LDFLAGS was never a valid concern since it is always inserted by a script.

This writes the 16-byte instance identifier to file descriptor specified by --identifier-fd if set, and closes the file.
This enables safely obtaining the new instance's identifier.

Should have done this when relocating this from container. Now is a good time to rename it before v0.3.x.

The SharePath is a more stable path than RunDirPath, since it is available all the time and should remain consistent. This also fits better into the intended use case of XDG_RUNTIME_DIR.

In some cases the signal might be delivered before the signal handler is installed, and synchronising against such a case is too expensive. Instead, use the pipe being closed as a fallback to the regular exit request. This change also moves installation of the signal handler early.

This change also spawns shim before committing system state, leaving it blocking on the setup pipe. The internal/outcome/process structure is also entirely reworked to be much more readable and less error-prone, while enabling basic performance measurements. A long-standing bug where segment lock is not held during Commit is also resolved.
Closes #19.
