debuginfod: PR27277 - Describe retrieved files when verbose
Allow users, with enough verbosity, to print the HTTP response headers
upon retrieving a file. These files may include several custome http
response headers such as X-DEBUGINFOD-FILE, X-DEBUGINFOD-SIZE, and
X-DEBUGINFOD-ARCHIVE. These headers are added from the daemon, in
debuginfod.cxx.
E.g output:
HTTP/1.1 200 OK
Connection: Keep-Alive
Content-Length: 4095072
Cache-Control: public
Last-Modified: Thu, 09 Sep 2021 19:06:40 GMT
X-FILE: debuginfod
X-FILE-SIZE: 4095072
Content-Type: application/octet-stream
