ash: add support for bash 'function' keyword
Where the POSIX shell allows functions to be defined as:
name () compound-command [ redirections ]
bash adds the alternative syntax:
function name [()] compound-command [ redirections ]
Implement this in ash's bash compatibility mode. Most compound
commands work (for/while/until/if/case/[[]]/{}); one exception is:
function f (echo "no way!")
The other two variants work:
f() (echo "ok")
function f() (echo "also ok")
function old new delta
