spi: Don't decode data lines if CS isn't asserted
Avoid decoding and outputting data from the SPI bus if the CS pin
hasn't been asserted. This avoids confusing both users and stacked
decoders which otherwise end up seeing traffic intended for other
chips (or just noise).
Note: The old behavior of decoding all traffic is still in place if
no CS pin has been wired up to the decoder.

Fix a few decoding bugs with arm_etmv3.
Fixed:
- wrong address decoding for some branches
- error in annotation lists for exception entry/exit
- exception was being thrown for 0E0N p-header packets
- fixes to objdump output parsing, better function name & source code matching
New features:
- added decoding of IRQ names for branch exception info
- added support for -C option to objdump to decode C++ symbol names
- put branches on the "Exceptions" annotation row when they contain exception info.

Improve uart decoder sample positions at high data rates.
At 3 samples per bit, the uart decoder took the value at the last sample
instead of the middle one. Improve calculations so that sampling is more
accurate at odd number of samples per bit.
Reworked in the algorithm:
- Fixed the polarity setting
- Taken in consideration the first transition
- Using the 'None' state instead of -1 and 0 value
- Simplify the algorithm and remove useless branches and variables
- Avoid re-calculating the same thing more than once
- Renamed a few variables for a better understanding
- Duty cycle precision changed to floating value
Otherwise:
- Added a meta OUTPUT for the duty cycle average
- Renamed the polarity option:
'polarity', 'active low/high' are well-understood terms.
- Added comments

spi: Tell stacked decoders about missing CS# signal.
This could previously be detected by the absence of a CS-CHANGE packet
before the first data packet, but it makes the stacked decoder simpler
if it is told directly.

configure.ac: Use AM_CFLAGS instead of CFLAGS.
CFLAGS, CPPFLAGS, LDFLAGS and so on are so-called "user variables" and
are meant for users of the package to use/override. The package itself
should not set or modify them in any way. Instead, the "shadow variables"
such as AM_CFLAGS, AM_CPPFLAGS, AM_LDFLAGS and so on, can be modified by
the package.

All PDs: Minor whitespace and consistency fixes.
- No newlines at the end of files.
- No trailing ';' characters.
- Comparison with None: Use 'is None' or 'is not None'.
- Comparison with True/False: Use 'if cond:' or 'if not cond:'.
- Various minor whitespace fixes.
For options which only have a limited set of valid values, we don't need
to check (in the PD) whether a valid value was supplied, since the backend
can do that for us.

All PDs: Drop unneeded exceptions.
In all current PDs it is not necessary to raise an exception upon
invalid states (of the PD's state machine), since we can guarantee that
no such invalid state can ever be reached in these PDs.

runtc: Fix incorrect include directive
runtc.c used to try to include "../config.h". This only works when
building in the source tree, otherwise there is no config.h in the
parent directory of runtc.c. However, the explicit path is
unnecessary since the build directory (whether the same as the source
directory or not) will always be added to the include path.

srd_decoder_load_all_path: Support zipimport paths
srd_decoder_load() works perfectly with decoders stored inside zip files.
However, srd_decoder_load_all{_path,}() did not, because it assumed that
normal directory listings can be used to enumerate decoders, which is not
the case for zipped decoders. Fix this by providing a fallback based on
the zipimporter Python class.
