SANE_Pid: Fix [-Wint-conversion] issues
...
Not all pthreads implementations use an integer type for pthread_t.
As a matter of fact, POSIX has explicitly withdrawn the requirement
that it must be an arithmatic type.
The musl C library uses a `struct __pthread *` which triggered the
warnings. As of this change, sanei_thread.h works around this by
providing two new macros to help keep this issue out of sight. All
backends have been changed to use these macros.

first set of CCDs, even though at some resolutions
we will not get any data from the second set.

Source code was inconsistent on how they were referencing

some preprocessor implementations anyways).

HP3500 backend:
...
Improve speed and reduce noise of most resolutions
Deal with an escape code discovered in the scanner's protocol
Use hardware detailed calibrations for resolutions up to 300
Use improved software detailed calibration for other resolutions
Add more debug information
Drop the 25dpi resolution
Make 200dpi the default (the same as the Windows frontend)
Add code (not used yet) to deal partially with grayscale and
lineart scanning
Use I18N strings where appropriate
