This patch makes several adjustments to the way f_mass_storage.c
handles its internal state and asynchronous notifications (AKA
exceptions):
A number of states weren't being used for anything.
They are removed.
The FSG_STATE_IDLE state was renamed to FSG_STATE_NORMAL,
because it now applies whenever the gadget is operating
normally, not just when the gadget is idle.
The FSG_STATE_RESET state was renamed to
FSG_STATE_PROTOCOL_RESET, indicating that it represents a
Bulk-Only Transport protocol reset and not a general USB
reset.
When a signal arrives, it's silly for the signal handler to
send itself another signal! Now it takes care of everything
inline.
Along with an assortment of other minor changes in the same category.
