event: generic event refactoring
Fix the behaviour of the following primitives:
- event_waitTimeout(): this is now implemented using a single
sig_wait() on the event's embedded sigmask. The timeout is notified
using a custom timer handler that sends the signal SIG_TIMEOUT to the
same event's embedded sigmask. This also fixes the hard-fault bug
reported by Nicolas Dandrimont:
(http://lists.develer.com/pipermail/bertos/2011-March/003164.html)
- event_select(): multiple event wait routine. Implement this
functionality mapping multiple events to different signal bits of the
process's sigmask and performing a single sig_wait() on that mask.
Signal bits are "allocated" internally by the event_select() itself and
must not be provided by the user.
NOTE: event_select() should be still considered an experimental feature,
so the API may change in the future (as reported in the documentation).

events: fix signal overlapping in generic events
When the kernel is enabled the generic events subsystem uses SIG_SYSTEM5
to synchronize the completion of the events.
The owner (process) of an event is assigned when the event is
initialized via event_initGeneric().
It may happen that the same process initializes more than one event, so
when one of them is triggered the process is awakened independently on
the event it is waiting for.
Fix this by moving the signal masks into the generic event structure and
export a new signal API to directly accept the signal masks, instead of
implicitly using the signal masks of the current process.

kbd: use generic event synchronization
At the moment kbd_get() is a blocking function that spins without
releasing the CPU until a key is pressed.
Without a voluntary preemption hook the cooperative kernel resuls
completely stuck when kbd_get() is called and no key is pressed.
This basically makes kbd_get() useless in the most part of the cases.
Change this behaviour making kbd_get() a sleepable function and use the
generic events infrastructure to notify the occurrence of key-pressed
events to the sleeping processes.
