Other method to avoid "unused var" compiler warnings.
...
The '(void)varname' method is nicer than 'varname = varname' and also
prevents warnings when compiling sigrok with clang instead of gcc.

Drop unneeded skeleton files.

They're not too useful as they mostly consist of a list of function names,
and that list is already available in the respective struct. The wiki
API docs and the code in the various hardware/output drivers serve as
useful examples already, no need for additional files.

Replace g_malloc{0,} with g_try_malloc{0,}.
...
The g_malloc()/g_malloc0() versions exit/segfault if not enough memory
is available, which is not a good thing in libsigrok.
Instead, we use the g_try_malloc()/g_try_malloc0() variants, which
return NULL if not enough memory is available, so that the caller can
handle the error properly.

gnuplot output: Optimize by only storing changes.
...
Only output new lines in gnuplot output if there have been changes in
the samples (similar to what VCD does). As long as the first and last
sample are output, the resulting plot looks OK.
This reduces the size of the output file from roughly 200MB to just 60KB
in one specific test setup (depends on the number of probes and on the
signal, of course). The time and CPU load required to generate the gnuplot
output and the resulting plot (PNG or other) is also drastically reduced
from multiple minutes to roughly 30 seconds (again, depends on various
things).
Thanks Ken Mobley of ChronoVu for the report.

libsigrok: Introduce sr_dbg/sr_info/sr_warn/sr_err.

now on, i.e. no more use of glib's g_debug() etc.
These functions are only for libsigrok, the frontends use whatever
logging mechanism is suitable there.

Fix out-of-tree build.
...
Use libtool "noinst" local helper libs and use one Makefile.am per
subdir, which is the usual/preferred method. These helper libraries are
purely local and will not be installed.
This also fixes out-of-tree builds of sigrok, i.e. building in a
directory other than the sigrok source directory, e.g.
$ cd /home/user
$ git clone ...sigrok
$ cd sigrok
$ ./autogen.sh
$ mkdir /tmp/foo
$ cd /tmp/foo
$ /home/user/sigrok/configure
$ make
$ make install
This will place all build results (.o files, .la files, etc) in the
local build directory (/tmp/foo) instead of the source directory
(/home/user/sigrok in this example). The installation directory is
selected via the --prefix configure option (/usr/local per default).
