Fix memory leaks by using stack instead of malloc
Reduce memory usage by having less temporary bufffers
Remove warnings by adding includes
Decrease code size by 608 bytes (mostly due to not linking malloc)
More robust handling of buffer overflows
There are now 3 potential locations to send HID reports:
1. USB
2. The bluefruit easy key
3. Adafruit BLE
Generally speaking, if USB is connected then we should prefer to
send the reports there; it is generally the best channel for this.
The bluefruit module has no feedback about bluetooth connectivity
so the code must speculatively send reports over both USB and bluetooth.
The BLE module has connectivity feedback. In general we want to
prefer to send HID reports over USB while connected there, even
if BLE is connected. Except that it is convenient to force them
over BLE while testing the implementation.
This policy has been extracted out into a where_to_send function
which returns a bitmask of which of the channels should be used.
This implements some helper functions that allow sending key reports
to an SPI based Bluetooth Low Energy module, such as the Adafruit
Feather 32u4 Bluefruit LE.
There is some plumbing required in lufa.c to enable this; that
is in a follow-on commit.
Modified the LUFA USB HID Descriptor to change the logical/usage
minimums for System Control from 0x01 (Mouse) to 0x81 (System Power
Down), this fixes OS X recognizing the Planck as having a mouse and
tablet, even with mousekeys off.
