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.

Trying to print to a shared stdout is a terrible idea. This change makes it possible to withhold output for the lifetime of the sandbox.

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 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.

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.

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.

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.

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

This implementation of shim accepts configuration as a gob stream over a unix socket, with support for mediating access to wayland via WAYLAND_SOCKET fd. All configuration is now included in the payload, and child is started inside bwrap configured with supplied bwrap.Config.
