* added comment
* replaced "~0" with the appropriate macro
* resolved -Wconversion
* saved some space by modifying AP_Param::add_vector_suffix (writing
behind buffer could happen, if buffer_size is almost uint16_max but this
can surely be ignored)

This bug affected parameters where the defaults are overridden in the
object constructor. For example, a PID object may have a default value
for PID_D of 0.0, but have a constructor based default of 0.2. If the
user tries to set the value to exactly 0.0, then the set wouldn't happen,
as the value matches the value in the object default var_info[]
table.
This change ensures we force a save to eeprom if the value is changing
from the current value, regardless of the var_info[] default.
Thanks to Tom Coyle for finding this bug!
- Allows use of hardware floating point on the Cortex-M4.
- Added "f" suffix to floating point literals.
- Call floating point versions of stdlib math functions.
This bug meant that setting a parameter in a parent class for a doubly
nested parameter group, where the parameter index in the parent class
is 4 or greater would actually set the first element in that parent
class.
At the moment only one parameter fits these narrow constraints - the
RCn_DZ element of the RC_Channel_aux class. So if someone set RC5_DZ
to 17 in ArduPlane it would actually set RC5_MIN to 17.
this stores the default value for all scalar variables in the var_info
table, which makes it possible to avoid storing default values in
eeprom. That allows us to oversubscribe the eeprom space with a much
lower risk of overrun.
* Eliminates recursive calls inside AP_Param.
This is important to Pat @ Galois, but not the project in general.
Recursion depth on these functions is bounded structurally using
existing nested group constructors (can't create loops in finite space)
and checked at init time
the variable CAM_P_G has the same prefix as the CAM_P group. We want
to allow for parameters having a common prefix with a group, so we
need to keep searching after we've found a group that matches the
prefix
We would like to be able to use Vector3f as a parameter while exposing
the individual elements of the vector as MAVLink parameters. This
change to AP_Param makes that possible, by giving AP_Vector3f a dual
personality
adding a idx element to the GroupInfo will make it less likely that a
developer will change the IDs of group elements, and make it easier to
see that these IDs are important for identifying a variable in EEPROM
The header packing has changed to make it 24 bits on all platforms,
which allows us to lower the EEPROM variable max size to 1024 bytes
