Hi,

I've attached a patch that adds man pages for a few libelf functions.
These man pages were originally generated using ChatGPT (model
GPT-4o).  I edited each man page by hand to help ensure brevity and
accuracy.

Parts of the original descriptions generated by ChatGPT have been left
as is.  I've attached the original man pages generated by ChatGPT for
comparison.

The prompt used to generate the man pages was:
  Write a linux man page for the function called <FUNCTION> in the open
  source project called elfutils.

My goal is to eventually add man pages for all elfutils library functions.
If the man pages in this patch are acceptable then I will use the above
method to create the remaining man pages.  I will post these to
elfutils-devel in batches to avoid the need for reviewing very large
individual patches.
