Uwe Hermann b53738baf7 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.

Uwe Hermann 50959ddcdc 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.

Uwe Hermann b08024a836 libsigrok: Introduce sr_dbg/sr_info/sr_warn/sr_err.
We should use these (internal) functions in libsigrok exclusively from
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.

Uwe Hermann cdb3573ceb input/output formats: s/extension/id/.
The struct entry 'extension' is not really a (filename) extension, but
rather a unique ID used for input or output formats, e.g. in the sigrok
CLI or GUI interface. Thus, rename it accordingly.

Uwe Hermann d494a4aa9d input/output formats: Explicit struct member names.
This makes it immediately clear what an entry is supposed to be, no
need to look it up in some header file.

Uwe Hermann 847c21bc65 Hook up output/text directory with autotools.

Also, add missing text.h to the list of source files.

2) No vcd output when using 1 MHz sampling on Sigma.

Uwe Hermann ab224f7b61 Initial support for the OLS output format.
This is the file format for the OpenBench Logic Sniffer "Alternative" client.
Details: https://github.com/jawi/ols/wiki/OLS-data-file-format

This is work-in-progress.
Currently the number of samples is hardcoded to 10000. Also, this will
require a real logic analyzer as input at the moment, and will not yet
work with the "demo" driver.
