Daniel Elstner 7c16e74d45 Build: Make dependency on git change more robust
It can sometimes happen that .git/HEAD or .git/refs/head/*, which
are added as config.status dependencies during configure, do not
exist anymore at build time.  For instance, when the current branch
is deleted after switching to a different one.

Wrap the dependencies inside $(wildcard ...) to avoid this problem.
Note that this is a GNU make feature.  However, it should be fine
as it is only used for git builds.  Even if a non-GNU make is used,
the construct will hopefully just expand to nothing.

Daniel Elstner 122322a9ba Build: Do not distribute generated headers
version.h and enums.hpp are generated at build time and should
not be included in the distribution tarball.  This seems to have
triggered a weird error when doing a VPATH build of the dist
tarball.

Daniel Elstner 9ac018d0fc Build: Pass nostdinc option to automake
It seems automake automatically adds the directory containing

Daniel Elstner 7f289d14ec Build: Append git revision hash to version
Append the git revision hash to the libsigrok package version,
unless HEAD exactly matches a release tag.  Note that this does
not affect the version known to autoconf -- e.g. source tarballs
created by make dist will not receive a revision suffix.

Changes to git HEAD automatically trigger a reconfiguration.
Uncommitted changes do not, which is why I left out the -dirty
suffix.

Daniel Elstner 27a2497dc2 Build: Delay expansion of $datadir in FIRMWARE_DIR
Make it so that $(datadir) is resolved at make time, as per
autotools recommendations.  Note that $datadir is not fully
resolved at configure time to begin with, i.e. part of it
already was evaluated at make time.

Daniel Elstner b2478a23db Build: Make version.h a configuration header
Use the proper tool for the job and make libsigrok/version.h
a secondary configuration header, so that autoconf's AC_DEFINE
machinery can be used to generate it.  Note that the header
template is still hand-written, enabling fine control of the
content.

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.

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.

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.
