Joel Holdsworth bf53457d1d Pass sr_datafeed_packets and payloads with const pointers
This patch marks packet structures and their payloads as const.
This indicates to packet receivers that modifications to these are
not allowed. In general all pointers should be marked const unless
modification of the referenced data is explicitly allowed.

Alexandru Gagniuc e7ed87a469 serial-dmm: Use dummy info struct for rs9lcd parser
The rs9lcd parser, which is used for the RadioShack 22-812 does not use its
*info parameter, and therefore did not have a rs9lcd_info struct declared.

With recent re-factoring of the receive data callbacks, it became necessary to
pass a struct pointer. This made the RECV_DATA macro look like:

- RECV_DATA(RADIOSHACK_22_812, metex14)

giving the wrong impression that the RadioShack 22-182 uses the
metex14 protocol, which is not the case.

Create a dummy rs9lcd_info struct, and correctly identify the parser
as rs9lcd in the RECV_DATA macro:

+ RECV_DATA(RADIOSHACK_22_812, rs9lcd)

Uwe Hermann a54dd31e38 serial: Use OS-independent flags for serial port opening.

mapped to the respective OS-specific mechanism in serial_open().

Bert Vermeulen 71caaad46b serial: allow for extra rts and dtr options in conn string
Options in addition to the usual "9600/8n1" syntax start with a
slash, and take the form of key=value, where different options are
also separated by slashes. For example:

	"9600/8n1/rts=0/dtr=1"

This sets RTS low and DTR high.

Alexandru Gagniuc a99e0d2a0c ols: Do not randomly probe serial ports
ols driver used to probe a series of available serial ports obtained
by regexp matching of common serial port names.
There are a number of problems with this approach:
1. It will probe all serial devices, including devices that do not
like to be probed, potentially causing them to act up.
2. It will try to probe serial ports which may already be opened in
other applications for other purposes.
3. It assumes the naming of the serial ports is set in stone, and
creates an unnecessary OS-specific list.
4. It produces unnecessary debug output even when an OLS device is
not connected.
5. etc...

Do not implicitly probe serial ports. Only probe the port specified
by the frontend, if any; otherwise, just quit.
Also get rid of all functionality in serial.c which was designed
specifically for random probing.

Tested on a Voltcraft VC-820 (FS9721_LP3) with the uni-t-dmm driver
(needs some small changes, tbd).

Bert Vermeulen 47211d65b4 sr: add probe list to device instance
There is no point in libsigrok copying probe lists around. The driver now
builds a list of probes according to the model device it found, and will
make that available to a frontend. The frontend thus has a reference of
what the driver has, including default names, and doesn't need libsigrok
to provide an unnecessary level of abstraction.

The sr_probe_new() library-private function is a helper for drivers.

libsigrok and libtool compile-time versions in it.
