ISO/IEC 19794-2:2005 Template IO

[fatboab]

Import/Export methods for reading/writing ISO templates from SourceAFIS.

Just realised we're not updating the template length in the file once we know it...

[fatboab]

Good to be merged now...

The test TemplateIO_ISO19794_2_2005 fails on my machine with: Expected 6 Was 500. originalDpi's are different

It segfaults on @olane 's machine.

I'm on cygwin on Windows. @olane is on a mac.

FWIW, running this through gdb on OS X points to this on failure:

Program received signal SIGSEGV, Segmentation fault.
[..] in TemplateIO_ISO19794_2_2005_Export [..] at Templates/TemplateIO.c:117
117         int16_t x = minutia->position.x;

Pointing to line 117 in TemplateIO.c as a possible issue?

Oh FFS! Turns out that on cygwin at least, the Unity TEST_SETUP stuff wasn't being called, so the template that was being written to disk was bogus. It's now failing on the Import portion of the test...

@andrew-farries @cjheppell so @david-connell and I have fixed it to run under cygwin and fixed the resulting memory leaks. With the memory leak stuff that @fffej did, we hope this means this is now good to be merged.

Are we going to use const consistently? I'd have thought both should be const in this situation?

[fatboab]

I have no idea, we need to decide on a few things like that and then apply them to all the code in another branch I think...
