While testing the new radioshack-dmm driver with pulseview, I found
a few inconvenients.
1. Print an info message when a port is probed, and when a device is
found. This makes it easy to tell if and where the driver is looking.
2. num_samples was not reset after the first aquisition, so the
second aquisition would quit right away. Reset num_samples at start
of a new aquisition.
3. There's no need to open the serial port RW, so change O_RDWR to
O_RDONLY when opening the port.
These changes are too trivial to split into different patches.

The Radioshack 22-812 can measure parameters such as transistor gain,
dbm, etc. Add those to libsigrok.h.
The SR_UNIT_UNITLESS is for quantities that do not have units. Any
ratio or gain are just factors, whic do not have units. Specifically,
a transistor's gain, or hFE, is a unitless quantity.

Only tested on U1233A, but it just might work.
The U125x protocol decoding only supports voltage, current, resistance,
capacitance and diode measurements for now.
This outputs text representation of SR_DF_ANALOG packets. Unlike the
float module however, it also outputs the standard abbreviations of
SI units corresponding to the packet's MQ and unit.
It also makes an effort to multiply or divide the floating point value
as needed to the nearest multiple or fraction, and inserts the
appropriate SI prefix to match.
The new output module callbacks will be init, recv and cleanup. The
existing data and event callbacks still work, but will be phased out
as existing modules get converted.
The recv() callback gets a copy of every packet on the session bus,
and thus has visibility of all metadata, allowing it to properly
output any acquired data.
Remove the session source once we are done loading the file, otherwise we'll
spin forever in sr_session_run.
