srd: nunchuk: Fix most annotation samplenumbers.
Also, add a self.putx() helper method, as most annotations we have right
now are exactly one I2C packet long (there will also be others later, though).

srd: Wii Nunchuk: Complete rewrite, PD works now.
The Nintendo Wii Nunchuk protocol decoder, while it was in the repo for
a while, didn't really work yet (among other things, due to lack of
dumps for testing the code).
This is fixed now, the rewritten decoder works fine with most dump
files in the sigrok-dumps repo. A few minor issues remain to be
added/fixed, though.
If the (generated) ChangeLog file is marked for DISTCLEANFILES, it'll be
removed whenever "make distclean" is called (and is then gone forever if
you use the tarballs, for example).

srd: onewire: Fix incorrect format for annotation output.
Should be a list containing:
- Annotation format number (e.g. 0, or ANN_DEC, etc).
- A list of strings (the annotation). If more than one string is
supplied, the other ones should be short versions of the string.
Example: [ANN_DEC, ["Foobarbaz", "Foo", "F"]]
As per guidelines in HACKING, the protocol "commands"/items should be ALLCAPS,
thus change 'data' to 'DATA'. Also, fix MX25Lxx05D protocol decoder
accordingly, currently the only one we have which stacks on top of SPI.
Add a new 'CS-CHANGE' output protocol item, which is sent upon every
change of the CS# pin value (either 0->1, or vice versa). This is needed
by various higher-level PDs.

sr/srd/cli: Fix compiling with Homebrew.
Add ACLOCAL_DIR setting and AM_PROG_AR macro for compiling with Homebrew
under Mac OS X.
Applies essentially the same change to
{libsigrok,libsigrokdecode,sigrok-cli}/{autogen.sh,configure.ac}
It may be that the same fix is needed for the other autogen.sh and/or
configure.ac files, but that hasn't been tested and therefore not in
this commit.

srd: Support for one or more optional probes.
In the protocol decoder you always get all required probes, then _all_
optional probes in the list of probes in the decode() call.
Example:
(r1, r2, r3, o1, o2, o3, o4) = pins
In this case r1-r3 are required probes, o1-o4 are optional probes.
However, the value of valid/used/specified probes will be 0 or 1,
whereas the value of probes that were not specified/assigned by the user
will be (at the moment) 42.
The PD can check for a valid probe like this:
if p in (0, 1):
...
Or check for an invalid probe:
if (p > 1):
...
The value of 42 could change to be -1 or None later.

srd: jtag: Various bugfixes.
Most importantly, both TDI and TDO are sampled at the rising TCK edge,
and only upon transitions from SHIFT-DR to SHIFT-DR and SHIFT-IR to SHIFT-IR
are we to save the TDI/TDO values (if I understood this correcly).
Also, start out in RUN-TEST/IDLE state for now. This is useful if you
have JTAG dumps which start "in the middle" somewhere, not in the
TEST-LOGIC-RESET state. For full dumps, the JTAG software usually issues
five TMS=1 cycles to force the JTAG state machine into TEST-LOGIC-RESET
anyway, so this works fine too.

srd: Drop ebr30a_i2c_demux in favor of i2cdemux.
The i2cdemux protocol decoder is the more generic version of the
obsolete ebr30a_i2c_demux decoder, and should be able (now or later) to do
everything that ebr30a_i2c_demux can do.
