remote_bitbang: Add SWD support
This adds new command characters to make SWD work with the new split
jtag and swd operations of bitbang.
The command characters are as follows:
O - SWDIO drive 1
o - SWDIO drive 0
c - SWDIO read request
d - SWD write 0 0
e - SWD write 0 1
f - SWD write 1 0
g - SWD write 1 1
Documentation has been updated accordingly. The new commands will be
used by an adapted version of the jtag-openocd applet of the "Glasgow
Debug Tool" (https://github.com/glasgowEmbedded/Glasgow). It has been
tested against an stm32f103 and an at91samd21 target.
contrib/remote/bitbang/remote_bitbang_sysfsgpio.c has also been adapted
to support SWD via the new command set. Some limited testing has been
done using a Raspberry Pi 2 with an stm32f103 and an at91samd21 target
attached.
