014b933b2b Add gdk-pixbuf support
When imaging support is required, we prefer to use gdk-pixbuf,
as it's already on things like Live CDs.
Also fix the examples building against the system libfprint.

7c44c86d4c Logging control
Don't log anything by default, and let the applications change the log
level.

c1f8581ec9 Cleanup discover_device in examples
Andrei Tchijov pointed out that the discover_device() function is written
in a strange way.

5485f8031d Return images through enroll/verify path
Added new API functions to obtain images, even when scans are bad, perhaps
a useful way to show the user just how good/bad the scan actually was.

Drivers and examples updated accordingly.

a86cd51959 Clean up on exit, and convert to singly-linked-lists
This adds fp_exit() to the public API, intended to be called while the
driving app is shutting down.

7e6f25908b remove imgdev abstraction from public API
Make it easier for application developers, don't have to care about this
level of abstraction which we're intending to make superfluous to them.

2709c6dc8c Basic image driver foundations
The basic model is that image drivers declare a fp_img_driver structure
rather than a fp_driver struct. fp_img_driver will contain primitive imaging
operations such as 'scan finger and return image'. The imgdev layer will
generically implement the primitive fp_driver operations, and the imgdev
layer will fix up the enroll/verify/etc pointers at driver registration
time.

Removed const from all fp_driver declarations, as these are now modified
dynamically in the case of imaging drivers.

680142f268 storage: add save/load functionality
Prints can now be saved to disk (but you currently must classify which
finger they are) and you can load them later.

Added 2 simple example programs to demonstrate this.

10bb96a0df Rename verify to verify_live
...to make way for an enroll example which stores on disk, and
a verify example that loads from disk.

39271b4fe5 Enrollment: improved error reporting
Convert enrollment function to return a signed integer, which is negative
on error or corresponds into fp_enroll_result otherwise.
Now we can treat a 'FAIL' condition differently from an actual error: fail
means that enrollment didn't complete because the data was nonsense or
whatever (e.g. scanned a different finger for each stage?).

Updated upekts accordingly.

50e2de0730 Enrollment tweaks
upekts will need to know when the first enrollment stage is attempted for
the first time, so add an __enroll_stage counter which actually indicates
the next stage to enroll. -1 is a special value and it means 0 is next *and*
it is the initial attemt.

Added more debug output to the enroll handler.
Added new fp_enroll_status codes for too short or uncentered scans.

Changed the print_data allocator to consider the device rather than the
driver, this feels more natural. Added missing return value.

Make fp_enroll_status codes start at 1. 0 can now be used as a
special/temporary value by the drivers. Also check that we aren't exceeding
the number of enroll stages.

Also add a missing exit() call to the verify example and update for the
above.

f81aa47a19 Add 'verify' example skeleton
This will become an example program to enroll a fingerprint and then
verify a finger against it.
