Add support to libbpf to append exception callbacks when loading a program. The exception callback is found by discovering the declaration tag 'exception_callback:<value>' and finding the callback in the value of the tag. The process is done in two steps. First, for each main program, the bpf_object__sanitize_and_load_btf function finds and marks its corresponding exception callback as defined by the declaration tag on it. Second, bpf_object__reloc_code is modified to append the indicated exception callback at the end of the instruction iteration (since exception callback will never be appended in that loop, as it is not directly referenced).

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.
