PR25548: support canonicalized source-path names in debuginfod webapi
Programs are sometimes compiled with source path names containing
noise like /./ or // or /foo/../, and these survive into DWARF. This
code allows either raw or canonicalized pathnames in the webapi, by
letting the client pass things verbatim, and letting the server
store/accept both raw and canonicalized path names for source files.
Tests included & docs updated.
