Add documentation for eBPF helper functions to bpf.h user header file. This documentation can be parsed with the Python script provided in another commit of the patch series, in order to provide a RST document that can later be converted into a man page. The objective is to make the documentation easily understandable and accessible to all eBPF developers, including beginners. This patch contains descriptions for the following helper functions: Helpers from Lawrence: - bpf_setsockopt() - bpf_getsockopt() - bpf_sock_ops_cb_flags_set() Helpers from Yonghong: - bpf_perf_event_read_value() - bpf_perf_prog_read_value() Helper from Josef: - bpf_override_return() Helper from Andrey: - bpf_bind() v4: - bpf_perf_event_read_value(): State that this helper should be preferred over bpf_perf_event_read(). v3: - bpf_perf_event_read_value(): Fix time of selection for perf event type in description. Remove occurences of "cores" to avoid confusion with "CPU". - bpf_bind(): Remove last paragraph of description, which was off topic.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
