debugcommands: add debugserve command

`hg serve --stdio` requires the exact command argument form
`hg -R <path> serve --stdio` for security reasons. An upcoming
commit will need to start an SSH protocol server process with
custom settings.

This commit creates a `hg debugserve` command for starting servers
with custom options. There are no security restrictions and we can
add options here that aren't appropriate for built-in commands.

We currently only support starting an SSH protocol server using
the process's stdio file descriptors. The server supports logging
its I/O activity to a file descriptor number passed as a command
argument.
