init() now only does whatever administrative stuff it needs (typically not
much), and returns an error code.
scan() can be called multiple times during the life of an application, and
returns a GSList of struct sr_dev_inst * of devices found during that scan.
The instances are a copy of the ones stored in the driver's own instance
list, to be freed by the caller with g_slist_free() only.
The scan() call can be passed a GSList of struct sr_hwopt *, to direct the
scanning.
A raw file descriptor to poll on is not always available, this patch adds
support for adding a source for a GIOChannel or GPollFD.

All frontends will have to include <libsigrok/libsigrok.h> from now on.
This header includes proto.h and version.h, both installed from the
distribution into $INCLUDE/libsigrok/ as well.
The only dynamically changed header is now version.h, which has both
libsigrok and libtool compile-time versions in it.
