rust-chg: add config validation and process returned instructions

This is the reimplementation of runinstructions() and main() in chg.c.

In Rust version, we only pass in early arguments to the server as the locator
doesn't know the full arguments. This should be fine since these arguments
are just passed in to _earlyparseopts() and _parseconfig(), which means the
server doesn't need full arguments.

Another difference is the handling of the "exit <code>" instruction. In Rust
version, we can simply reuse the connection instead of "exit(code)" as the
command error isn't displayed yet. That's because the client-side stdio is not
attached until the connection is validated. This behavior is cleaner than C,
but it also means that the early server exception wouldn't be propagated to
client because stderr isn't attached. So we might have to reconsider when to
attach/detach the server stdio.
