This reverts support for RCInput via PWM. This is causing trouble in
some RPI-based boards, receiving a SIGSEGV. Let's revert it for now and
retry this later.
This reverts commit 5629f38b2c.
This reverts commit 51fd0b3d55.
This reverts commit 79d56073f7.

This reverts commit 8cca0beba9.
The PWM input using the RPI DMA is causing trouble with RPI boards using
PPMSUM. Let's revert it until the solution is found. We still leave the
ifdef in RCInput for BH hat.
This commit changes the way libraries headers are included in source files:
- If the header is in the same directory the source belongs to, so the
notation '#include ""' is used with the path relative to the directory
containing the source.
- If the header is outside the directory containing the source, then we use
the notation '#include <>' with the path relative to libraries folder.
Some of the advantages of such approach:
- Only one search path for libraries headers.
- OSs like Windows may have a better lookup time.
DMA is getting stopped in the separate method now. This is the best we
can get at the current time. It does yield slightly better experience
and works in the majority of cases.
The patch is a no bulletproof solution, though.
There's a possibility of corruption in case of e.g. a SIGKILL. There's
no signal framework at the time and the commit doesn't add one. That's
why all signals are handled in the same erroneous way. This is not a
good nor a final solution to the issue.
For the issue at hand a better fix might be porting the code to kernel
space but it's a rather tediuos task that we cannot undertake in the
couple of weeks.
