659d8346be Compiler flags update
Dropped -Wextra as it is not that useful.
Set compiler flags to be more like the kernel's.
Set std=gnu99
Fixed some warnings.

c5a550e42c Add Authentec AES1610 driver
This is an active capacitance swipe-type device similar to but smaller
than the AES2501.

Image processing performance is good but matching performance is not so
good. The bozorth3 matcher needs tweaking in order to better cope with
small sets of minutiae.

With a lowered threshold, matching performance is good enough for now.

2ad14c0212 Add AES2501 driver
This driver works quite nicely. Seems a little too sensitive though (too
much black in the standardized image, not enough ridge gap definition).

Processing results are quite good, but you need a good enrollment image
(i.e. long!). It's best to get such images by pressing harder than you
might think necessary and swiping slowly.

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.

07a81b07be upekts: initialise and deinitialise device during verify/capture
Otherwise it heats up, and verify retries fail because we didn't end the
session.

294f9ad447 Improve print_data structure and on-disk format
Drivers now have an ID number. These will be assigned by me and documented
on the wiki. 0 cannot be used.

Drivers now define a devtype for each device they initialise. This is to
cope with the situation where a driver can support varying devices where
their print data is incompatible (i.e. image scaling is totally changed).
This doesn't apply to any existing supported devices.

Print data no longer includes driver name, and includes driver ID instead.

Paths to saved print data now include driver ID and devtype, and no longer
include driver name.

APIs exposed for converting a print_data into a blob which can then
be loaded back again later. Useful for systems who don't want to use
my simple storage system (which is only aimed at a single user).

File format is now defined and will be documented on the wiki. The header
is larger as we can no longer rely on directory paths in all scenarios.

Print data compat check now checks devtype and driver ID.

6b8d17ef26 Add bozorth3 from NBIS; implement verify for image devices
uru4000 works splendiferously (YAY!)
aes4000 is going to need some work though :(

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.
