SERVER: add support for API16 so we could run latest KTX

Seems like there is some issues, minor testing was done under MacOS,
had to compile without optimizations since it crashed with optimizations,
unfortunatelly it doesn't crash without optimizations so was not able to debug it.

Also need to revisit cmodel.c since during "merge" it lost recent sanity checks validations.
