Instead of going through 'hal' then 'scheduler', use directly the AP_HAL
functions. Besides removing indirection that is not necessary for such
functions, this patch ends up reducing the code size in the call sites.
For example, building ArduCopter for PX4 with this change (compared to
before introduction of the functions) yields almost 3k bytes of code
size.
# ArduCopter build before the functions (1b29a1af46)

# ArduCopter build after this patch
text data bss dec hex filename

A later patch will remove the unused functions in the Schedulers.
The PSTR is already define as a NOP for all supported platforms. It's
only needed for AVR so here we remove all the uses throughout the
codebase.
This was automated with a simple python script so it also converts
places which spans to multiple lines, removing the matching parentheses.
AVR-specific places were not changed.
Merged a bug fix where mode would not revert on geo-fence disable.
The mode would not revert if the switch was in position 0.
Geofencing will soon be in Rover and I didn't want to forget this bug
and chase it later so committing it now. It works fine in Rover now
even though the geofencing code isn't in yet.
