kernel: generalize awake
...
Awake can now interrupt several blocking syscalls (even
during note handling).
Among others, it can interrupt await, pread and pwrite.
It cannot interrupt several others for different reasons:
- awake cannot be interrupted by awake;
- syscalls like remove and create can be used for kernel comunication
and it would be hard to know if the effect occurred in the
receiving fs if they were interrupted;
- other syscalls do not need awake since they just provide access
to kernel infos (eg seek or fd2path)
NOTE: awakes registered before a note cannot occur during the note
handling and will be deferred till the next call to noted.

qa: ensure awake works correctly in signal handlers
...
Jehanne's notes (like Plan9 ones) are not reentrant.
Thus an alarm can not be used to interrupt a syscall in a note handler.
Awake instead works properly also in a note handler.

qa: introduce runners and more tests for newlib
...
For each test, if a script exists with the same name of the test
plus the .runner suffix, the runner is run instead of the test.
As a first example qa/lib/newlib/testsuite/atexit is run by
qa/lib/newlib/testsuite/atexit.runner.
These .runner scripts allow more complex checks of the side effects
generated by the test.
