shim: user switcher process management struct
test / test (push) Successful in 19s Details
This change moves all user switcher and shim management to the shim package and withholds output while shim is alive. This also eliminated all exit scenarios where revert is skipped.

shim: kill shim if setup becomes impossible
test / test (push) Successful in 23s Details
This prevents a hang when setup faults but the shim keeps waiting on the socket. Setup is automatically aborted when the shim is killed.

shim: abort setup on failed start and process exit
test / test (push) Successful in 25s Details
Shim setup listens on a socket in the process share, if shim setup hasn't happened on exit revert will fail. This change makes sure shim setup is aborted on a doomed launch.

fmsg: produce all output through fmsg
test / test (push) Successful in 17s Details
The behaviour of print functions from package fmt is not thread safe. Functions provided by fmsg wrap around Logger methods. This makes prefix much cleaner and makes it easy to deal with future changes to logging.

app: move wayland mediation to shim package
test / test (push) Successful in 29s Details
Values used in the Wayland mediation implementation is stored in various struct fields strewn across multiple app structs and checks are messy and confusing. This commit unifies them into a single struct and access it using much better looking methods.

app: move app ID to app struct
App ID is inherent to App, and it makes no sense to generate it as part of the app sealing process.

app: port app to use the system package
This commit does away with almost all baggage left over from the Ego port. Error wrapping also got simplified. All API changes happens to be internal which means no changes to main except renaming of the BaseError type.

helper/bwrap: ordered filesystem args
The argument builder was written based on the incorrect assumption that bwrap arguments are unordered. The argument builder is replaced in this commit to correct that mistake.

init: custom init process inside sandbox
Bubblewrap as init is a bit awkward and don't support a few setup actions fortify will need, such as starting/supervising nscd.

app: tag ACL operations for revert
ACL operations are now tagged with the enablement causing them. At the end of child process's life, enablements of all remaining launchers are resolved and inverted. This allows Wait to only revert operations targeting resources no longer required by other launchers.

app: remove bubblewrap launch method
Launch methods serve the primary purpose of setting UID in the init namespace, which bubblewrap does not do. Furthermore, all applications will start within a bubblewrap sandbox once it has been implemented.

app: clean up interactions and handle all application state and setup/teardown
There was an earlier attempt of cleaning up the app package however it ended up creating even more of a mess and the code structure largely still looked like Ego with state setup scattered everywhere and a bunch of ugly hacks had to be implemented to keep track of all of them. In this commit the entire app package is rewritten to track everything that has to do with an app in one thread safe value.

In anticipation of the client/server split also made changes:
- Console messages are cleaned up to be consistent
- State tracking is fully rewritten to be cleaner and usable for multiple process and client/server
- Encapsulate errors to easier identify type of action causing the error as well as additional info
- System-level setup operations is grouped in a way that can be collectively committed/reverted
  and gracefully handles errors returned by each operation
- Resource sharing is made more fine-grained with PID-scoped resources whenever possible,
  a few remnants (X11, Wayland, PulseAudio) will be addressed when a generic proxy is available
- Application setup takes a JSON-friendly config struct and deterministically generates system setup operations
