selftests/bpf: Store BPF object files with .bpf.o extension BPF object files are, in a way, the final artifact produced as part of the ahead-of-time compilation process. That makes them somewhat special compared to "regular" object files, which are a intermediate build artifacts that can typically be removed safely. As such, it can make sense to name them differently to make it easier to spot this difference at a glance. Among others, libbpf-bootstrap [0] has established the extension .bpf.o for BPF object files. It seems reasonable to follow this example and establish the same denomination for selftest build artifacts. To that end, this change adjusts the corresponding part of the build system and the test programs loading BPF object files to work with .bpf.o files.

selftests/bpf: Switch to new btf__type_cnt/btf__raw_data APIs Replace the calls to btf__get_nr_types/btf__get_raw_data in selftests with new APIs btf__type_cnt/btf__raw_data. The old APIs will be deprecated in libbpf v0.7+.

selftests/bpf: Add remaining ASSERT_xxx() variants Add ASSERT_TRUE/ASSERT_FALSE for conditions calculated with custom logic to true/false. Also add remaining arithmetical assertions: - ASSERT_LE -- less than or equal; - ASSERT_GT -- greater than; - ASSERT_GE -- greater than or equal. This should cover most scenarios where people fall back to error-prone CHECK()s. Also extend ASSERT_ERR() to print out errno, in addition to direct error. Also convert few CHECK() instances to ensure new ASSERT_xxx() variants work as expected. Subsequent patch will also use ASSERT_TRUE/ASSERT_FALSE more extensively.
