jitter, pwm: Avoid Unicode string literals
It seems the Python we ship along our Windows binaries does not
support u"..." strings, even though it's been a language feature
since Python 2. Remove the "u" prefix to avoid a syntax error.
Also, consistently use format "%.1f" at all scales.

Build: Include <config.h> first in all source files
Since Autoconf places some important feature flags only into the
configuration header, it is necessary to include it globally to
guarantee a consistent build.

log: Remove srd_log_logdomain_{get,set} from the API
The confusingly named srd_log_logdomain_set() simply set a global
string prefixed to the log message by the default log callback.
This is pretty much useless, misleadingly named, and not used by
either sigrok-cli or PulseView.

jtag_stm32: Fix incorrect handling of registers.
The STM32F10xxx has two serially connected JTAG TAPs, the boundary scan tap
(5 bits) and the Cortex-M3 TAP (4 bits). See UM 31.5 "STM32F10xxx JTAG TAP
connection" for details.
Due to this, we need to ignore the last bit of each data shift (and we
currently ignore the 5 bits of the boundary scan tap).

Build: Define feature test macro _DEFAULT_SOURCE
This basically makes glibc expose the same set of features as
if gcc was invoked without any restricting -std=c* option. Unlike
_GNU_SOURCE however, it does not enable GNU-specific extensions.
So, with this macro defined the behavior of Linux with glibc
should match that of other platforms.

In order to avoid confusion of the flags-gathering pkg-config

Build: Reduce autogen.sh to trivial stub
Use autoreconf instead of invoking the various Auto tools
separately. Get rid of the Darwin-specific guesswork -- it does
not make sense to handle this at the level of libsigrokdecode.
People should set up their ACLOCAL_PATH themselves as appropriate
for their own system; just as they already need to set up various
other paths.

Pass unitsize per sample chunk.
Don't pass unitsize to srd_inst_channel_set_all(), have that only
set the channel map. Instead, srd_session_send() now has a parameter
for the unitsize which is passed with every new chunk to be decoded.
This is in preparation to fix issues with devices or files which
have a unitsize != 1 and where the "guessed" unitsize based on the
number of channels is not correct.
This also allows for (potential) future changes where every chunk can
indeed have a different unitsize.

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

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
