This removes the syscall cutoff thresholds, instead declaring all
syscall number constants in package ext.
This also removes two constants from package container which were
inadvertently exported for 386 and amd64.

This arranges for binfmt entries to be registered for the container.

These are generally useful, and none of them are container-specific. Syscalls subtle to use and requiring container-specific setup remains in container.

This package is not container-specific.

This package is quite useful. This change allows it to be imported without importing container.

This frees all container instances of side effects.

This makes it possible to optionally omit the identifying verbose message, for when the Op implementation can provide a much more useful message in its case, using information not yet available to the String method.

These are now handled by init. This eliminates generic WrapErr from mount and procPaths.

This passes line information and handles strconv errors so it reads better.

These are also now handled by init properly, so wrapping them in self is meaningless and unreachable.

The mount function now wraps its own errors in a much more descriptive type with proper message formatting. Wrapping them no longer makes any sense.

There are significant limitations to using the overlay mount, and the implementation in the kernel is quite quirky. For now the Op is quite robust, however a higher level interface for it has not been decided yet.

These literals were missed when the constants were first defined.

This increases readability since this can help disambiguate absolute paths from similarly named path segments.

The mountTmpfs helper is a relatively low level function that is not exposed as part of the API. Prefixing sysroot here not only introduces overhead but is also quite error-prone.

This improves code readability and should also be useful for callers choosing to preserve CAP_SYS_ADMIN.

This allows slightly easier use of the vanity url. This also provides some disambiguation between low level containers and hakurei app containers.
