debuginfod 1/2: client side
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.
