When a test case is annotated with __retval tag the test_loader engine would use libbpf's bpf_prog_test_run_opts() to do a test run of the program and compare retvals. This commit allows to perform arbitrary actions on bpf object right before test loader invokes bpf_prog_test_run_opts(). This could be used to setup some state for program execution, e.g. fill some maps.

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.
