The version field in the norma-dmm driver state struct is initialized, but
never read and the same information is also already available in the
sr_dev_inst struct version field. So remove it to simplify the code.
This allows to get rid of the custom dev_close() callback and just use the
standard std_serial_dev_close() instead.

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.
