This series introduces a simplified implementation of strscpy() to
selftests/bpf and then replaces strcpy/strncpy usages across the tests
with it.

For context see a discussion that prompted this series [1].

Ihor Solodrai (7):
  selftests/bpf: Add simple strscpy() implementation
  selftests/bpf: Add strscpy_cat()
  selftests/bpf: Replace strcpy() calls with strscpy()
  selftests/bpf: Replace strncpy() with strscpy()
  selftests/bpf: Use strscpy_cat() in the test_loader
  selftests/bpf: Use strscpy in bpftool_helpers.c
  selftests/bpf: Use memcpy() for bounded non-NULL-terminated copies
