RFC: Add ELF note for description with JSON data

Hi Sebastian,

Yes, sorry.  I did not read your original email properly.

I would have no objection to adding this particular note type.
It would be best if if this was agreed upon by the ELF ABI folks though.

Personally I would prefer not to complicate readelf by adding another
dependency.  Are there tools that can read JSON output from a pipe ?

I was thinking that it might be reasonable to add an option to readelf
along the lines of --note-body-parser=<program> and have it pass the
contents of any note it is displaying to <program>.  This would allow
for any kind of formatting inside notes, and would not add any dependencies
to readelf.
