Refactor ELF section handler definitions table to use a set of flags and unified SEC_DEF() macro. This allows for more succinct and table-like set of definitions, and allows to more easily extend the logic without adding more verbosity (this is utilized in later patches in the series). This approach is also making libbpf-internal program pre-load callback not rely on bpf_sec_def definition, which demonstrates that future pluggable ELF section handlers will be able to achieve similar level of integration without libbpf having to expose extra types and APIs. For starters, update SEC_DEF() definitions and make them more succinct. Also convert BPF_PROG_SEC() and BPF_APROG_COMPAT() definitions to a common SEC_DEF() use.

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.
