In the case where we are unable to get a path for loading libs, and
instead just use LIBDIR, we set 'src = strdup(LIBDIR)'. However, we
never update orig_src to point to src before tokenizing the path with
strsep(), so the memory is never freed.
Update load to always set orig_src to src so that we don't leak memory.
Some scanners (notably the Mustek 1248UB) doesn't like receiving a
STOP scan command when it is not scanning. Flag prevents it my making
sure that START/STOP commands are only ever paired up.
We have seen this from buggy backends that present NULL for constraint
string_lists. This is probably illegal behaviour from backends but we
don't want to crash.
Calling this function upsets some scanners in this family.
This temporary sticking plaster permits the Mustek 1248UB scanner to
scan after cancelling. We need to look into this much more when a
scanner becomes available for investigation.
Enable autofocus support on my Epson 12000XL. The middle of the scan
area will be used as the focus point. An arbitrary X,Y is possible but
not implemented yet

Allow the whole range of manual focus settings as an expert option. This
is also now independent of a TPU being installed or not. The old default
values are applied if the user changes the source type (either FLATBED
or TPU). Adding a focus group here because autofocus options will come
with later patches.

coolscan2 has focus entries already reused in coolscan3. Because I want
to add the same options to epson2, it makes sense to make them available
globally. Add i18n while here.

Even with USB based scanners, we need to send the esci command to set
the focus. There is no byte in the extended scanning parameters for it.
So, move the code to a place where it is called for all cases.

- restructure fine calibration code
- initial support for uploading fine calibration payloads
- improve DR-C225 support
Most canon scanners require that the driver apply fine (per-cell)
calibration information. But a few require that the info be loaded
into the scanner. Here, we add initial support for that, though the
needed values are hardcoded instead of calculated.
On many systems now python executable it is python3.
On my system it the case and by this muild failed with:

Using AM_PROG_PYTHON() nmacro cllows avoide tha by hecks current version of the
python and allw to use custom python executable by execute configure by:
$ PYTHON=</some/python> ./configure <params>
AM_PROG_PYTHON aclocal macro propagates to automake files $(PYTHON) variable
which could be used on geberate instaleable scripts on duting build process like
it is now in backend/Makefile.am.
Currently minum version of required vesion of the python is python >= 3.
Now that we no longer include generated files in our git repository
builds should always have maintainer mode enabled so checkouts pick
up on changes in Makefile.am, configure.ac, etc. between builds.
See #350.
