Use the new software limit helper functions rather than open-coding their
functionality.
This also fixes the issue that the driver does not reset the limit
statistics in acquisition_start(). It also makes the time limit work, which
previously was only a stub implementation.

Since Autoconf places some important feature flags only into the
configuration header, it is necessary to include it globally to
guarantee a consistent build.
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.
- Don't use strerror() on error codes from functions that don't set
errno. Replace strerror() with sr_strerror() for libsigrok functions.
Set this new parameter to 0 (no timeout) at every call site. This is
consistent with previous behaviour, so cannot cause any regressions.
Waiting forever for a serial operation is clearly always wrong. Without
specific knowledge of each device and driver however, I can't choose
appropriate timeouts for each call. The maintainers of these drivers
will need to do so, and also add appropriate handling of timeouts.
When this commit is merged, a bug should be entered for each driver
that is touched by it.
This call is executed from an event handler context was previously
nonblocking, however there is no handling for a partial write.
The output buffer is unlikely to be full and the commands to be sent
are short, so it should be OK to make this a blocking call.
