used extensions such as .gpi, .gnu, .gnuplot, .gp, .plt, .gih,
others. These files don't contain data, only Gnuplot commands such
as 'set yrange [75:105]', 'set ylabel "foo" offset 1', and so on.
- "data files": This is what libsigrok reads and writes. These files
contain actual data to be graphed by Gnuplot (with the help of a
specially-crafted control file, see above). The data is usually in
a tab-separated format. The common file extension is usually .dat,

Fix FreeBSD issue with libusb_get_port_numbers()
Currently (as of date 20150122) an ioctl problem within the
FreeBSD kernel is preventing libusb_get_port_numbers() from working.
Hence calls to libusb_get_port_numbers() will always return 0.
This makes it impossible to establish a physical path the the usb device.
This problem has existed "forever" -
meaning that libusb_get_port_numbers() has never worked.
A fix is committed to FreeBSD "current" head -
and will later be merged (MFC'ed) to maintenance branches.
See: https://svnweb.freebsd.org/base?view=revision&revision=277417
Additionally FreeBSD requires that devices prior to calling
libusb_get_port_numbers() have been opened with libusb_open().
The patch is "forwards-compatible".
Currently it acts specificly to libusb_get_port_numbers()
currently returning 0 on FreeBSD.
In these situations it constructs an artificial path to the device.
When FreeBSD kernels appears with proper working ioctl
supporting libusb_get_port_numbers() the code will construct
proper physical paths for newer kernels - while still generating
artificial physical paths for older defective kernels.
Add new config options to libsigrok - 'averaging', which allows to
enable averaging of samples and 'avg_samples' for setting the number
of samples to be averaged over in each cycle.

Limit frames instead of samples.
Since every individual measurement is represented by a single frame
and a "sample" isn't all that meaningful concept in this context,
it makes more sense to define possible limit in number of frames.

a sample limit.

Use frames to group a single measurement result together.
In most, but not all, modes the ES51919 reports two separate
analog values for each measurement sample. These values are
mapped to two separate channels and sent in two separate
packets.
A client program needs a way to determine which results are
parts of the same measurement and also know when a complete
measurement is received so it can process the sample. Use
the frame begin and end packets to separate groups that each
represent a single complete measurement.

Use g_malloc0() for small allocations and assume they always

Don't always sanity-check parameters for non-public (SR_PRIV)
