* drivers/input/stmpe11_tsc.c: Fix some status checks so that the touchscreen
interrupt handling logic does not read data if the fifo is not at the
threshold level.
* include/nuttx/wqueue.h: Add macro work_available() to determine if the
previously scheduled work has completed.
* drivers/stmpe11_tsc.c: Correct errors: (1) Since all interrupt logic is done on
the worker thread, disabling interrupts does not provide protected; Need to
disable pre-emption. (2) Fix handling of touch ID and (2) add some logic to
prevent certain kinds of data overrun.
