Remove vague statements from the README. On all current distributions,
the udev paths are identical, anyone deliberately deviating from the
defaults should be able to handle it by themselves.
Rules in /etc/udev/rules.d/ should only be used for customization, or
for locally built packages.
Split the distribution independent database from the access policy rules.
This avoids warnings due to granting permissions to the commonly unknown
plugdev group, and allows simple overrides of the used access policy.
The "uaccess" tag has to be added before the "seat" rule is evaluated.
The upstream default for the seat rule is "71-seat.rules", so use
60-libsigrok.rules for appropriate lexicographical sorting.
Also use a dash instead of underscore, the latter is commonly used as a
replacement character of unsafe characters in autogenerated identifiers.
This fixes bug #1059.
Some drivers used locale dependent functions for converting strings
to float/double values. These functions fail when the decimal mark
is a "," in the locale settings but the string contains a ".".
This fixes bug #1064.
A "low samplerate" in this case means anything where
samples_todo is less than SAMPLES_PER_FRAME. This case
wasn't handled properly before, resulting in wrong
amounts of data being sent out.
We can't use the memory size command because it returns
the *maximum* memory used, not the *actual* memory used.
Hence, we only know the number of samples per div once
sample data actually comes in.
As there is a huge range of supported LeCroy scopes, naming
the IDN response for every single one of them is going to be
impossible. Hence, it makes more sense to treat all LeCroy
devices as if they were scopes and supported. This approach
lets users try to see how far they get and if they run into
issues, they can then be treated separately - e.g. by creating
a custom device profile.
Unless we do this, the vast majority of LeCroy scopes will
not be recognized by the driver.
Set samplelimit to a sane value (was causing PulseView to
crash earlier), as well as advertise samplerate using SR_CONF_LIST
so that PulseView can show the sample rates.

The function drains off all the remaining data in the receive socket
and is triggered before starting a capture and after a capture is
completed. In the absence of this function, there is a possibility of
data corruption and also the NodeJS TCP server throws an error if the
buffer is not completely read out before the socket is closed.

BeagleLogic now supports two modes of interface - one being the
native mode running on an ARM system like the BeagleBone Black
and the other mode acting like a TCP client for the BeagleLogic
server running off a BeagleBone compatible system. This makes it
convenient for desktop users to retrieve samples from BeagleLogic,
no more copying files and SSHing into the BeagleBone hardware in
order to use BeagleLogic.

Organize driver functions into an ops structure (there will be
separate structures for both native and TCP mode of operation).

The code earlier was in a single .h file, so it's now separated into a C file
and H file

If a channel in the higher-than-8-bit group is enabled then use
16-bit captures. Otherwise just do 8-bit captures.

This is unlike the previous behavior to return 8 channels and then
use logic_channels to get all the 14 channels

Values like '-0.1' would be parsed as being positive, as the integral
type does not discern +0 and -0. Also allow values without leading
integral value, to match behaviour of strtod/sr_atof.
