PR29472: debuginfod: add metadata query webapi, C api, client
This patch extends the debuginfod API with a "metadata query"
operation. It allows clients to request an enumeration of file names
known to debuginfod servers, returning a JSON response including the
matching buildids. This lets clients later download debuginfo for a
range of versions of the same named binaries, in case they need to to
prospective work (like systemtap-based live-patching). It also lets
server operators implement prefetch triggering operations for popular
but slow debuginfo slivers like kernel vdso.debug files on fedora.
Implementation requires a modern enough json-c library, namely 0.11,
which dates from 2014. Without that, debuginfod client/server bits
will refuse to build.
% debuginfod-find metadata file /bin/ls
% debuginfod-find metadata glob "/usr/local/bin/c*"
Refactored several functions in debuginfod-client.c, because the
metadata search logic is different for multiple servers (merge all
responses instead of first responder wins).
Documentation and testing are included.
