Proposal: Add getFullProgName

[Kazu Yamamoto ( 山本和彦 )]

Hello,

> getFullProgName :: IO String
> getFullProgName =
>     alloca $ \ p_argc ->
>     alloca $ \ p_argv -> do
>         getFullProgArgv p_argc p_argv
>         peek p_argv >>= peek >>= peekCString
> 
> foreign import ccall unsafe "getFullProgArgv"
>     getFullProgArgv :: Ptr CInt -> Ptr (Ptr CString) -> IO ()

P.S.

I would also like to have an API to change the process name for
daemon.
