Yauheni Kaliuta	7a85e4dfa7	selftests/bpf: Pass page size from userspace in map_ptr ... Use ASSERT to check result but keep CHECK where format was used to report error. Use bpf_map__set_max_entries() to set map size dynamically from userspace according to page size. Zero-initialize the variable in bpf prog, otherwise it will cause problems on some versions of Clang.

Andrey Ignatov	b1b53d413f	selftests/bpf: Test access to bpf map pointer ... Add selftests to test access to map pointers from bpf program for all map types except struct_ops (that one would need additional work). verifier test focuses mostly on scenarios that must be rejected. prog_tests test focuses on accessing multiple fields both scalar and a nested struct from bpf program and verifies that those fields have expected values.
