Uwe Hermann d258022db0 baylibre-acme: Drop unneeded comment.
There's indeed no g_fclose() unfortunately. The g_*() wrappers for file
handling are mainly there to deal with portability issues in file names
(encoding, character sets, etc) on different platforms.

Aurelien Jacobs c33ff3771b rigol-ds: fix search for the closest vdiv.
We try to find the smallest diff by comparing each diff with
the previously known smallest diff, so initially, this smallest diff
should be INFINITY so that we are sure to find a smaller one.

This fixes the following exception:

These are available on e.g. Rigol DS1102E (or "upgraded" DS1052E).

Without this, if one of the channels happens to have been set to
one of the missing vdiv settings frontends (e.g. PulseView) will
have some trouble using the scope:

Aurelien Jacobs 73931b7cc7 input/vcd: fix parse_header() return value check.
Mixing tests for both a boolean and an SR_ERR at the same time is not
really a good idea.
parse_header() actually returns a boolean so only check if it returns FALSE.

This fixes the following gcc-5 warning:

Aurelien Jacobs 2617c81a4b Remove the inline qualification from sr_rational_set().
Inlining can only happen in the same compilation unit where the
function was defined, so there is no sense declaring an inline
function in a header if this function is not defined in this
same header.

This fixes the following gcc-5 warning:

Aurelien Jacobs ee29d92e14 Correctly copy sr_datafeed_meta in sr_packet_copy().
Commit 5801d558 replaced g_slist_copy_deep() by some incorrect code
that actually leaks the newly allocated memory, instead of doing
a deep copy.

This new version should be more correct, more concise, and it fixes
the following warning:

Uwe Hermann 8656a71790 output/gnuplot: Use .dat as suggested file extension.
Gnuplot doesn't have any "official" file name extension(s). It uses
(at least) two different types of files basically:

 - "control files": These can have many different somewhat commonly
   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,
   though many others are possible as well.

Uffe Jakobsen 19643b96e2 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.
