Daniel Elstner c1aae90038 Build: Set local include directories in Makefile.am
Move the include flags for files in the source tree from
configure.ac to Makefile.am where they belong.  Also use
AM_CPPFLAGS instead of CFLAGS/CXXFLAGS to make sure the
files in the build/source tree are always picked up first.

Also, remove the include/libsigrok sub-directory from the
search path, thereby making the <libsigrok/> prefix mandatory
when building libsigrok itself.  This matches the convention
already imposed on users of the library.

- Don't #include <errno.h> in files that don't actually need it.

   errno. Replace strerror() with sr_strerror() for libsigrok functions.

Hubert CHAUMETTE 6c7d80afca libsigrok: demo: close pipes on dev_acquisition_stop()
Fixes a bug where new acquisition failes due to leftover pipes from
previous acquisitions:
	sr: demo: dev_acquisition_start: pipe() failed
Indeed, PulseView had 2024 pipes opened. With this fix, it stabilizes at
33 with sampling thread active.

Move the libusb_detach_kernel_driver() call after the code that

in a segfault.

  #0  libusb_kernel_driver_active (dev=0x0, interface_number=0) at libusb/core.c:1711

Bartosz Golaszewski 7e5a048ff2 baylibre-acme: Add a workaround for slow data acquisition.
At high sampling rates and maximum channels we are not able to acquire
samples fast enough, even though frontends still think that samples
arrive on time. This causes visible shifts in frontend plots.

To compensate for the delay introduce the following workaround: check
if we are late (if any clock events have been missed) and resend the
last frame n times (n == number of missed clock events).

Daniel Lezcano a0648b1a12 baylibre-acme: Use timerfd instead of a fake pipe.
Currently baylibre-acme uses a fake pipe as the input channel required by
libsigrok API and calls sleep() in the data acquisition callback to create
intervals between measurements.

Switch to a more elegant approach: use Linux' timerfd and set a periodic
timer equal to the sampling rate. Then read the data every time the timer
expires.

Daniel Lezcano 4e88b86cc8 baylibre-acme: Optimize reading of values from sysfs.
Opening a file has a cost (security, allocation, syscalls). The
read_sample() function always does an open/read/close sequence.

In order to optimize that, let's open the file at the moment the
acquisition starts, close it when the acquisition stops and make
read_sample() only lseek() to the beginning of the file and read
the value.

Daniel Elstner fe473123ba sysclk-lwla: Do not create channels in reverse order
This was originally done as an optimization in combination with a list
reversal which has since been removed from the code.  Thus, un-reverse
the channels so that the UI lists them in the correct order again.

Alexandru Gagniuc aae2273b99 bindings/python: Handle import failures without crashing
When the import of gi.repository.GLib failed, we would get a NULL
pointer that we passed along without any checking. In this situation,
the entire program would crash with a segmentation fault, and no
message to indicate the problem.

When the import fails, abort the SWIG init and print a message. The
Python interpreter then prints out a backtrace, which can be useful
in tracking down the problem.
