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*"

readelf: display dynamic symtab without section headers

This commit adds a new option "-D/--use-dynamic" to support printing the
dynamic symbol table from the PT_DYNAMIC segment. By using the
PT_DYNAMIC segment, eu-readelf can go through the contents of dynamic
section entries and the values of each tag. From that, we can get the
address and size of the dynamic symbol table, the address of the string
table, etc.

By using the new option "-D/--use-dynamic", eu-readelf can list the
symbols without section headers.

Example:
  $ ./src/readelf -Ds a.out

If we don't find any debug information for a given frame, we usually

been compiled with frame pointers, in which case we can look up the

Support note NT_FILE for locating files.

Martin Milata:
------------------------------------------------------------------------------
RFE: dwfl_core_file_report: use NT_FILE core note if the link_map chain is broken
https://bugzilla.redhat.com/show_bug.cgi?id=1129777

The dwfl_core_file_report function follows dynamic linker's link_map chain in
order to determine the shared libraries used by the executable. As this data
structure is located in writable memory it can be overwritten by garbage, which
is sometimes the case.
 https://github.com/abrt/satyr/issues/127#issuecomment-46957546

Since version 3.7 (commit 2aa362c49), Linux kernel adds NT_FILE note to core
files which contains the files mapped by the process, including shared
libraries.
------------------------------------------------------------------------------

dwfl_core_file_report now tries to fall back on NT_FILE if the link_map chain
is broken.

elfutils would already find the appropriate binary file from
/usr/lib/debug/.build-id/ symbolic links. But those symbolic links do not have
to be present on the system while NT_FILE still points to the correct binaries.

Filenames from the note NT_FILE are used only if link_map filenames failed to
locate matching binaries.

tests/test-core.core.bz2 had to have its NT_FILE disabled as run-unstrip-n.sh
otherwise FAILs:
FAIL: 0x7f67f2aaf000+0x202000 - . - /home/jkratoch/redhat/elfutils-libregr/test-core-lib.so
PASS: 0x7f67f2aaf000+0x202000 - . - test-core-lib.so
As test-core-lib.so is found in link_map but it is not present on the disk
elfutils now chooses the more reliable filename from NT_FILE (although that
filename is also not found on the disk). Updating the expected text would be
also sufficient.
