ash,hush: tab completion of functions and aliasestab_completion2
Since commit 9e2a5668f (ash,hush: allow builtins to be tab-completed,
closes 7532) ash and hush have supported tab completion of builtins.
Other shells, bash and ksh for example, also support tab completion
of functions and aliases.
Add such support to ash and hush.
