Implement support for SR_CONF_PROBE_FACTOR setting in BayLibre ACME
driver. Given the channel-group parameter this allows to set the
shunt resistance for each probe.

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:
sr: rigol-ds: Negative vdiv index: -1.
Caught exception: not applicable
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:
sr: hwdriver: sr_config_get(): key 30012 (vdiv) sdi 0x11bcb70 cg CH1
sr: rigol-ds: Negative vdiv index: -1.

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:
src/input/vcd.c: In function 'receive':
src/input/vcd.c:506:34: warning: logical not is only applied to the left hand side of comparison [-Wlogical-not-parentheses]
if (!parse_header(in, in->buf) != SR_OK)

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:

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:

In order to determine the target OS when cross-compiling libsigrok
we need autotools to set the 'target_os' variable. This macro
determines the system type and sets output variables to the names
of the canonical system types.

(lwla_convert_trigger): Fix trigger mask computation bug introduced
by recent change: Widen constant to 64 bit before shifting so that
channel nunmbers beyond 32 are processed correctly.
By avoiding g_slist_copy_deep() for now, we can easily allow libsigrok
to build against glib 2.32 (less hassle for users of stable/older
distros or OSes).
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.
- 'struct sr_input *' variables are consistently named 'in'.
- 'struct sr_input_module *' variables are consistently named 'imod'.
- 'struct sr_output *' variables are consistently named 'o'.
- 'struct sr_output_module *' variables are consistently named 'omod'.
Fix "undefined reference to `sigrok::EnumValue<sigrok::LogLevel,
sr_loglevel>::_values'", which happens at least when using clang(++),
e.g. on Linux, Mac OS X, or FreeBSD.
This fixes bug #534.
Thanks to Uffe Jakobsen and Martin Ling for reporting and investigating!
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.
