shinkos6145: Major additions

* Remove S6145 fallback code if there is no library found.
   (Quality was very poor, and I'm not going to make a version for
    the S2245)
 * Remove most awareness of the S6145 correction data structure, and make
   the corrdata structure an opaque blob + len., and get rid of the
   extra padding.  Except for what we need to pass in the print parameters.
 * Attach to the S2245 library if needed
 * S2245 library in the printing flow.

In order to generate usable output, the Sinfonia CHC-S6145 and CHC-S2245
printers (and their siblings listed above) require the input data to be
transformed using specific image processing algorithms.
The library that implements this processing is dynamically loaded
at runtime. There are three options:
* libS6145ImageProcess -- Supported by Sinfonia, this is a proprietary
library only available for x86 and x86_64 linux targets. It can be
obtained by politely contacting your local Sinfonia distributor.
* libS6145ImageProcess and S2245IP -- Supported by Sinfonia, these
are proprietary libraries. They can be obtained by politely
contacting your local Sinfonia distributor.
If you have the appropriate permission fron Sinfonia and its
technical and legal limitations are acceptible to you, we recommend
you use the supported libS6145ImageProcess library, as it will
generate the highest quality output.
If you have the appropriate permission fron Sinfonia and their
technical and legal limitations are acceptible to you, we
recommend you use these official supported libraries.
* libS6145ImageReProcess -- GPL'd re-implementation of the Sinfonia
algorithms, available as source. It is a drop-in replacement
that appears to generate identical output to the proprietary
Sinfonia library.
* libS6145ImageReProcess and libS2245ImageReProocess -- GPL'd
re-implementations of the Sinfonia algorithms, available as
source. They are drop-in replacement that appears to generate
identical output to the proprietary Sinfonia libraries.
DISCLAIMER: Sinfonia Inc was not involved in the creation of
libS6145ImageReProcess and is not responsible in any way for any
these libraries and is not responsible in any way for any
deficiencies in its output. They will provide no support if it is
used.
Do *NOT* contact Sinfonia for support if you are using
libS6146ImageReProcess!
libS6146ImageReProcess or libS2245ImageReProcess!
(Please see the full disclaimer in libS6145ImageReProcess.c)
* If neither of the above libraries are found, the backend will
fall back to a very crude algorithm that generates low-quality
results not suitable for photographic output

libS2245ImageReProcess.c)
