Add Cyrustek ES51922 DMM chip parser.
serial-dmm: Add UNI-T UT61E support (UT-D02 cable).
ols: Implement SR_DI_HWOPTS.
rigol-ds1xx2: Initial driver skeleton.
rigol-ds1xx2: First working version.

Add gnuplot_rigol_ds1xx2.gpi gnuplot script.

This is a very simple gnuplot script for testing the Rigol DS1xx2 driver.
It currently has various issues and limitations (e.g. only one channel
is displayed, the scaling is not usable, and so on) to be fixed later.
Rewrote the link-mso19.c into api and protocol. Still need to test and cleanup some more
Removing the old link-mso19 files and changing makefile
Added missing mso functions
Added flow control to serial configuration to support xon/xoff for link-mso19
More cleanup. Communication with mso19 is working, but its not triggering. Need to check why.
Eveything seems to work now except for triggers.
Rewrote the trigger config. Added trigger position and trigger slope
Added limit samples Eveything seems to work find up to 1024 samples
configure.ac: Enable Link Instruments MSO-19.

This driver now compiles again and (partially) seems to work, so enable it.
link-mso19: Fix (C) lines.

Bring back the original (C) lines from before the split into api.c
and protocol.[ch].
