This allows fact information to be validated in the underlying source files,
but requires us to explicitly maintain this in appropriate version-tagged, and
architecture-tagged files. This is more explicit and safer.
This mechanism uses a special regular expression for matching a +checkconst
stanza to validate constant values, sizes and offsets. This applies to both Go
source files and assembly files.

This avoids the cost at startup time and allows the resulting function to
be more effectively inlined to call sites. Although these are not widely
used at the moment, this change may also be used as an example for code
generation in similar cases.

Similar to Linux, we should add pseudo-filesystem iouringfs in gVisor to back
IO_URING's file descriptors. We start with stubbing `io_uring_setup(2)` so it
provides a file descriptor backed by anonfs.

This makes it easier to implement dynamically sized types in go-marshal. You
really only need to implement MarshalBytes, UnmarshalBytes and SizeBytes to
implement the entire interface.
By using the `dynamic` tag, the autogenerator will generate the rest of the
methods for us.
This change also simplifies how KernelIPTGetEntries implements Marshallable
using the newly added utility.

This PR adds the following:
- [x] Marshall-able structs for fuse headers
- [x] Data structures needed in /dev/fuse to communicate with the daemon server
- [x] Implementation of the device interface
- [x] Go unit tests
This change adds the `/dev/fuse` implementation. `Connection` controls the
communication between the server and the sentry. The FUSE server uses
the `FileDescription` interface to interact with the Sentry. The Sentry
implmenetation of fusefs, uses `Connection` and the Connection interface
to interact with the Server. All communication messages are in the form
of `go_marshal` backed structs defined in the ABI package.
This change also adds some go unit tests that test (pretty basically)
the interfaces and should be used as an example of an end to end FUSE
operation.
