crosh: move remaining global code into functions
With this, we have very little code outside of functions now. Just
the initial traps, bash re-exec, and the main call. This follows our
shell style guide and makes it easier to reason about the code.
BUG=None
TEST=ran crosh and tested commands still worked
TEST=ran crosh with --usb and --dev and --dash and made sure things worked
