Bug#678718: unicap: implicit pointer conversions due to missing function prototypes

[Adam Conrad]

Source: unicap
Version: 0.9.12-1
Severity: important
Justification: causes segfaults on most non-32-bit arches

Hi, the Ubuntu amd64 buildd spotted an implicit pointer conversion
issue with your package[1].  Turns out, on closer inspection, that
several source files seem to be macroing to libv4l2 functions
without including the libv4l2.h header.  I'll follow up with a
patch once debbugs gives me a bug number to reference. ;)
