selftests: bpf: break up test_progs - preparations
Add new prog_tests directory where tests are supposed to land. Each prog_tests/<filename>.c is expected to have a global function with signature 'void test_<filename>(void)'. Makefile automatically generates prog_tests/tests.h file with entry for each prog_tests file: #ifdef DECLARE extern void test_<filename>(void); ... #endif #ifdef CALL test_<filename>(); ... #endif prog_tests/tests.h is included in test_progs.c in two places with appropriate defines. This scheme allows us to move each function with a separate patch without breaking anything. Compared to the recent verifier split, each separate file here is a compilation unit and test_progs.[ch] is now used as a place to put some common routines that might be used by multiple tests.
