Check whether a sample limit was actually set (> 0) before checking if
that sample limit is reached. This also fixes continuous acquisition mode
for drivers which have that.
Implement SR_HWCAP_LIMIT_MSEC capability, to allow acquisition to automatically
stop after a specified amount of time.

Some unusual modes required re-parsing the value. Instead of assigning the
re-parsed value to *floatval, it was reassigned directly to *analog->data;
however, analog->data is not initialized at this point, causing a segfault.
This situation was created when moving the radioshack-dmm code to serial-dmm,
with the segfault not being observed at that time.
Do not write directly to analog->data, but instead use the intermediate
variable rawval.

Convert bit masks from hardcoded hex values to bit shifts. For example 0x80
becomes (1 << 7). This also fixes a typo error in the definition of INFO_DIODE.
Add comments explaining that some case values in sr_rs9lcd_parse() are meant to
fall through without a 'break;', and explain some of the unusual modes.

Unfortunately the device doesn't have an EEPROM on board at all, and so
initially enumerates with the default Cypress FX2 VID:PID (04b4:8613).
Since we already support using plain FX2* as basic logic analyzers using
the fx2lafw firmware, we cannot support that same VID:PID for the
OsciPrime. Therefore a USB conn is required for the initial scan.
However, once the firmware is uploaded the device re-enumerates as
04b4:1004, which we do detect for scanning automatically.
Thus, the OsciPrime driver requires one scan with conn parameter to get
the firmware uploaded, but it will then keep working until powered off.
Some sources may not be necessarily associated with a device. The best example
is the anykey pollfd from sigrok-cli. sr_session_stop only removes sources
associated with hardware devices via dev_acquisition_stop. Sources such as
anykey are not removed, and thus session->num_sources will not get to 0. As a
result, we may get into situations where the event loop enters an infinite
state.
To prevent this, all we have to do is remove any active sources that are still
present after dev_acquisition_stop has been called for all devices.
This fixes bug 14.
This is the driver model agreed upon for all drivers.
As a result of the split, a devc->num_probes field had to be added in order to
reduce the interdependence between api.c and protocol.c .

sr_serial_dev_inst_free() freed all members of sr_serial_dev_inst, but did not
free the struct itself, as expected from a free_*() function. This inadvertently
caused a memory leak in every place sr_serial_dev_inst is used.
Free the struct itself
+ g_free(serial);

serial-dmm does not check if a sample limit is actually in place before deciding
to stop acquisition. Since the sample limit is set at 0 by default, operating
in continuous mode will cause acquisition to stop before even sending the first
sample.
Check to make sure we actually are in a sample-limited mode before stopping for
this reason.

PKG_CHECK_MODULES() checks for libusb-1.0 via pkg-config already, no
need to use a "manual" additional check via AC_CHECK_LIB() just to set
HAVE_LIBUSB_1_0 in config.h.
This helps with cross-compiling setups, among other things.
The alsa driver was out of date wrt APIs and libsigrok conventions in
general, and wasn't compiling.
This fixes the compile and updates it to _basically_ work with the current
state of analog support in libsigrok.
This is not finished/full support for ALSA analog sampling yet, though,
various TODOs remain that will be addressed later.
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.
Hardware scanning creates an ftdi_context before attempting to locate devices
based on PID/VID. If no devices are detected, execution jumps to cleanup. The
context is freed with free(), instead of ftdi_free().
We cannot assume that the libftdi context is stored in a contiguous memory
region, and thus cannot use a simple free. Case in point, this situation is
identified by valgrind as a "definitely lost" memory leak.
Use ftdi_free() instead of a simple free() in hw_scan(). Valgrind no longer
complains about a memory leak in this area.
clear_instances() does not need any modification, as it correctly uses
ftdi_free().

commit 378abfeac6 tried to solve a bug where
the fx2lafw driver would print "Device came back" even if a timeout had occured.
It solved that issue, but inadvertently introduced a new bug:
"Device came back" would be printed even if no firmware upload was performed.
This is counterintuitive, as the device is only reset when a firmware upload is
performed.
There are three cases:
i) Firmware upload was successful
ii) Firmware upload failed
iii) Firmware upload was NOT needed
Each case warrants a separate message from the driver. Print the
following messages depending on the outcome:
i) "Device came back"
ii) "Device failed to renumerate"
iii) "Firmware upload was not needed."

Use the new DRIVER_LOG_DOMAIN mechanism, where explicitly writing
the driver name in the message string is no longer required.
Thus:
- sr_err("fx2lafw: Something bad happened.");
becomes:
+ sr_err("Something bad happened.");
In either case, the log output is the same.

This works with the UNI-T UT-D02 (RS232) cable. For the USB/HID
based cable (UNI-T UT-D04), the uni-t-dmm driver must be used.
Note: This is untested, but should work just fine for all settings, with
the possible exception of temperature (testers needed!)
Just use the 'int dmm' + wrapper method that is used for all other
functions which need this information. There is no real need to
special-case the hw_dev_acquisition_start() API call here.
Having concentration as a unit is vague, as it can be expressed in
many ways. In the context of sigrok, concentration means a normalized
number from 0 to 1.
Document its meaning.
