Cormac Shannon 39d6cc95cb Add command execution runtime (lcmd.c, lcmd.h) ...

Implements luaB_command: fork/execvp with pipe-captured stdout/stderr,
argv parsing with quoting/escaping, and non-blocking pipe reading via
select(). Backs the __command() calls emitted by the backtick parser.

Resolves #03 and #04.
