This commit adds a tool that parses the libbpf.map file in the libbpf sources, then finds specific annotations in libbpf userspace pages and inserts the version tags for the functions in question. Signed-off-by: Dylan Reimerink <[email protected]>
This commit adds pages for the libbpf_{major_version, minor_version,
strerror} functions. These are simple functions, pages were added to
prove the libbpf-tag-gen tool works as expected.

The spellcheck will output its best guess for the location of misspelled words in the markdown files. This is useful for the user to quickly find and fix the misspelled words. However, the output also includes the project root, which is likely different for every system including the host vs in a docker container. By removing the project root from the output, we get a relative path which most terminals can use to open the file as long as the working directory is the project root.

A few helper functions have been updated with a new `__bpf_fastcall` attribute. This commit updates the helper function signatures to reflect this change in the libbpf headers. Signed-off-by: Dylan Reimerink <[email protected]>

The PR adds a new tool to generate Libbpf version tags for userspace API functions. To prove it works, this PR also adds a few pages. Stumbled across a spellcheck usage issue while running it on the new pages and fixed it. And while running the
make generate-docswe got some helper function updates which I decided to also commit while at it.
