Bug#1063051: vnlog: NMU diff for 64-bit time_t transition

[Dima Kogan]

Hi. vnlog does not depend on time_t. Is it too late to stop this
update?

The abi-compliance-checker failure is here:

  https://adrien.dcln.fr/misc/armhf-time_t/2024-02-01T09%3A53%3A00/logs/libvnlog-dev/base/log.txt

That error message says what the problem is: you are not supposed to
#include vnlog.h directly. Instead you're supposed to use the
"vnl-gen-header" tool (also in the "libvnlog-dev" package) to produce
usable headers that themselves #include vnlog.h. For instance:

  vnl-gen-header 'int w' 'uint8_t x' 'char* y' 'double z' > vnlog_fields_generated.h

If you then run vnlog_fields_generated.h (which, again, #includes
vnlog.h) through abi-compliance-checker, you'll see that it passes.
vnl-gen-header doesn't support any time-related types, so this is y2k38
safe.

Thanks.
