This extends the session file format to contain logic data files named
either "logic-1" as before, or "logic-1-1", "logic-1-2", ...
representing chronologically ordered chunks of captured data.
The chunks are transparently concatenated together by sr_session_load().
This exposes the list of devices added to the session. In the case of
loading a session from file, these struct sr_dev_inst are otherwise
not exposed to the frontend. See bug 145.
This DMM is not using the standard bits in the FS9922 protocol/structure
to indicate the "volt" and "diode mode" flags. Instead, it only sets the
user-defined bit "z1" to indicate both "diode mode" and "volt".
This fixes#142.
This is no longer used, and also it is not available on Android and thus
breaks cross-compilation for Android.
Thanks Marcus Comstedt <marcus@mc.pp.se> for reporting.
For demux mode we half the channels. Previous check method broke
the OLS randomly and but it in a bad state.

demux mode allows DDR sampling which disables group 2 & 3
and thus samples group 0 & 1 to sample on rising and falling of
the clock.

Allow channel groups to be swapped. This is useful
for demux at 200mhz with the unbuffered channels.

The high bit of the sample, denoting this is a count, was not getting
properly cleared. This resulted in an inevitably negative count, and
corruption of the sample buffer before it was transferred to the
frontend.
The single sample buffer, up to 4 bytes long, was not getting initialized
on (every) acquisition start, only after the first full sample was in.
This caused the first sample to potentially hold garbage.
ols allows both external and internal test patterns at ~20khz
which are helpful for unit tests and demos.
pattern=internal -> route pattern internally to all 32 pins
(input otherwise disabled)
pattern=external -> generates pattern on unbuffered pins 16:31
(which can be looped back to the buffered pins 0:15)

Stage count was always getting incremented one more than
actual stages, and this caused a extra stage with zero'ed data
probe lines to have the start bit field.

The map_eeprom_data function is currently unknown. The map entries
provided were observed via bus-snooping of the vendor software on my
device. Other devices may need additional values.
Since the uni-t-ut32x series handles devices with the same USB VID.PID,
which is linked to the WCH CH9325 USB/HID-UART interface chip, this
driver can no longer assume it can handle anything with this VID.PID.
The last release (0.2.0) had the libtool version (current:revision:age)
set to 1:0:0. Since this release doesn't add/change/remove any
interfaces, only 'revision' is increased, resulting in 1:1:0.

Frontends using libsigrok don't need to be recompiled or relinked.
