Extend the debuginfod client API with a function to stuff outgoing
headers into libcurl http transfers. Use this from debuginfod so
federated trees of debuginfod/httpd can trace back to to the
originating client for administrative purposes. Docs & test included.

This function lets a client know, during or after a progressfn
callback, what the url of the winning outgoing download is/was.

Add a pair of functions to associate a void* parameter with a client
object. Requested by GDB team as a way to pass file names and such
user-interface data through to a progressfn callback.

Add a mandatory debuginfod_begin()/_end() call pair to manage a client
object that represents persistent but non-global state. From libdwfl,
dlopen the debuginfod.so client library early on. This hopefully
makes sure that the code (and the libcurl.so dependency) is loaded
before the program goes into multi-threaded mode.

For interactive clients such as gdb, interruptibility is important for
usability during longer downloads. This patchset adds a
download-progress callback function to the debuginfod client library,
with which a caller app can interrupt a download as well as be
notified of its quantitative progress.
Introduce the debuginfod/ subdirectory, containing the client for a
new debuginfo-over-http service, in shared-library and command-line
forms. Two functions in libdwfl make calls into the client library to
fetch elf/dwarf files by buildid, as a fallback. Instead of normal
dynamic linking (thus pulling in a variety of curl dependencies),
the libdwfl hooks use dlopen/dlsym. Server & tests coming in patch 2.
