Changelog:
----------
v1 -> v2:
- Wrap entire function signature in BPF_KFUNC macro instead of using
__bpf_kfunc tag (Kumar)
- Update all kfunc definitions to use this macro.
- Update kfuncs.rst documentation to describe and illustrate the macro.
- Also clean up a few small parts of kfuncs.rst, e.g. some grammar, and
in general making it a bit tighter.

bpf: Add BPF_KFUNC macro for defining kfuncs
bpf: Document usage of the new BPF_KFUNC macro
