This patch adds a function for a common operation of all serial based drivers.
It extracts the serial options from the options linked list that is passed down
to every hardware driver.
This patch adds a function to read and parse a SCPI response which contains a
comma separated list of unsignet 8-bit integer numbers (e.g "1,0,64").
This is particularly useful if the instrument sends digital measurement data
in this format.
This patch adds a function to read and parse a SCPI response which contains a
comma-separated list of floating-point numbers (e.g. "1.0e-5,2.0e-4,3.0e-3").
This is particularly useful if the instrument sends analog measurement
data in this format.
The SCPI standard specifies the "*OPC?" command (Operation complete query) which
queries the instrument for its operative state. When all pending operations are
complete, the instrument responds with a "1".
Some manufacturers block before completing all operations and don't respond
with anything and some of them respond with a "0". This function handles both
cases uniformly.
This patch adds helper functions to read an SCPI response and parse the response
as an integer, boolean, floating-point or double-precision floating-point number.
The Standard Commands for Programmable Instruments (SCPI) defines a standard
for syntax and commands to use in controlling programmable test and measurement
devices.

This patch adds helper functions for sending SCPI commands, reading a SCPI
response and reading and parsing a SCPI "*IDN?" response.
This patch adds helper functions for converting a string to different number
formats (double, long, float, int).
These functions are exposed in the public API.
SR_CONF_PATTERN_MODE was not handled in config_list(), yielding
non-working OLS support in PulseView (due to an assert), and a missing
pattern list in sigrok-cli's --show output.
This fixes bug #184.
