Introduce a new function debuginfod_set_verbose_fd which will produce
verbose output on a given file descriptor (STDERR_FILENO if the
environment variable DEBUGINFOD_VERBOSE is set) showing how the search
for a particular client query is going.
Example output:
debuginfod_find_debuginfo 1234567890
server urls "https://debuginfod.elfutils.org/ http://dbgd.usersys.com:3632/"
checking build-id
checking cache dir /home/mark/.cache/debuginfod_client
using timeout 90
init server 0 https://debuginfod.elfutils.org/
url 0 https://debuginfod.elfutils.org/buildid/1234567890/debuginfo
init server 1 http://dbgd.usersys.com:3632/
url 1 http://dbgd.usersys.com:3632/buildid/1234567890/debuginfo
query 2 urls in parallel
server response HTTP response code said error
url 0 The requested URL returned error: 404 Not Found
server response HTTP response code said error
url 1 The requested URL returned error: 404 Not Found
not found No such file or directory (err=-2)

debuginfod-find -v enables a progressfn that prints the Progress every
time the callback is called. For slow transfers or big downloads this
can be really verbose (hundreds a times a second). Slow it down a bit,
so it only prints the progress at most 5 times a second.

The license itself was correct, just the comment to get a copy of
the LGPL was wrong.

By using dwelf_elf_begin instead of elf_begin we automatically get
support for determining the build-id of compressed (kernel) images.

Extend the debuginfod-find command line interface to permit
/file/names instead of only buildid hexadecimal strings.
v2: move code into debuginfod-find; client API remains buildid only.

Hardcoding argv[2] is wrong in presence of -v option. Code
immediately following did the correct argv[] indexing already.

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.
