Add selftests validating libbpf's auto-resizing of load/store instructions when used with CO-RE relocations. An explicit and manual approach with using bpf_core_read() is also demonstrated and tested. Separate BPF program is supposed to fail due to using signed integers of sizes that differ from kernel's sizes. To reliably simulate 32-bit BTF (i.e., the one with sizeof(long) == sizeof(void *) == 4), selftest generates its own custom BTF and passes it as a replacement for real kernel BTF. This allows to test 32/64-bitness mix on all architectures.

README
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
