Shell: Start implementing a POSIX-compliant parser

Browse source

The parser is still very much a work-in-progress, but it can currently
parse most of the basic bits, the only *completely* unimplemented things
in the parser are:
- heredocs (io_here)
- alias expansion

For now, this is not attached anywhere, a future commit will enable it
for /bin/sh or a `Shell --posix` invocation.
