Log Message:
Some fixes for the do_install() function:
- Make all the functions called from do_install() return an error code,
so that we can abort install if something went wrong.
- Add a 'errstr' argument to run_prog(), which if not NULL is displayed
with msg_printf() and followed by process_menu(MENU_ok) if the command fail.
Used to warn the user that the current action is aborted.
- in a few places use msg_display() or msg_printf() rather than printf.
It seems that stdout/stderr are not always pointing to the active curses
window.
- garbage-collecd unused messages, add a few new one (error handling).
XXX only tested on i386. Other md parts should be tested as well.
