Fix finding split debug info files not located by the build-id mechanism
[This bug has been found by using elfutils in the context of
libabigail. The initial bug report is
https://sourceware.org/bugzilla/show_bug.cgi?id=18792. The
interesting comments start at is
https://sourceware.org/bugzilla/show_bug.cgi?id=18792#c4]
suppose we have a debug info file that is located at a
/prefix1/usr/lib/debug/prefix2/libfoo.so. Suppose also that the debug
info describes a binary that is located at /prefix1/prefix2/libfoo.so
Suppose the debug_link property inside the binary
/prefix1/prefix2/libfoo.so correctly contains the string "libfoo.so"
that designates the name of the debug info file.
The problem is, when find_debuginfo_in_path() is called with its
file_name parameter set to "/prefix1/prefix2/libfoo.so" and
mod->dwfl->callbacks->debuginfo_path set to
"/prefix1/lib/debug/", it fails to locate the debug
info file libfoo.so under "/prefix1/usr/lib/debug/prefix2/".
This patch fixes the issue by making find_debuginfo_in_path() try all
the sub-strings of "/prefix1/prefix2/libfoo.so "under"
"/prefix1/usr/lib/debug/", to find libfoo.so. That is, it tries, in
order:
- /prefix1/usr/lib/debug/prefix1/prefix2/libfoo.so
- /prefix1/usr/lib/debug/prefix2/libfoo.so <-- and boom, it finds it!
Note that the patch tries the variations between the two candidates
above too.
The patch uses a goto. I dislike gotos like anyone else, but then
here, not using this would imply a bigger change of the logic of that
function. So I am proposing the scheme based on the goto instead.
* libdwfl/find-debuginfo.c (find_debuginfo_in_path): Try to locate
the debug info file named debuglink_file under
mod->dwfl->callbacks->debuginfo_path, by looking at the set of
sub-trees under mod->dwfl->callbacks->debuginfo_path which is
common to the set of non-absolute parent trees of file_name.

libdwfl: Add dwfl_core_file_attach and dwfl_linux_proc_attach.
Rewrite __libdwfl_attach_state_for_pid and __libdwfl_attach_state_for_core
as public functions and don't call them from dwfl_linux_proc_report and
dwfl_core_file_report anymore. This lets the user attach state explicitly
independ from how the dwfl modules have been reported. Since attaching
state is an explicit action now the error can be returned directly and we
don't need to keep track of process_attach_error. dwfl_linux_proc_attach
lets the user can tell libdwfl whether caller takes care of ptrace
attaching and stopping the threads under inspection, or whether the
callback needs to take care of that and detaching again.

libdwfl: Add dwfl_getthread_frames.
dwfl_getthread_frames is a convenience function for when the user is only
interested in one specific thread id of a process. It can be implemented by
a simple wrapper function that removes an extra callback layer just to
filter on thread id. But it also provides an optimized path to getting
access to just one particular Dwfl_Thread of the Dwfl process by providing
and (optional) new callback for the state provider. The pid_thread_callbacks
now provide an (optional) pid_getthread that doesn't need to travers all
threads anymore. Which is implemented for the linux-pid-attach provider.
stack now uses this to implement a new '-1' option that shows just one
specific thread of a process.

libdwfl: Introduce dwfl_module_getsym_info and dwfl_module_addrinfo.
Some arches like ppc64 use function descriptor values instead of function
addresses causing matching of names and addresses to fail when using
dwfl_module_getsym or dwfl_module_addrsym.
Add ebl hook to resolve any function descriptor values found in non-ET_REL
modules.
The new function dwfl_module_getsym_info doesn't adjust the symbol value
in any way, but returns the adjusted and/or resolved address associated
with the symbol separately. The new function dwfl_module_addrinfo resolves
against both the address associated with the symbol (which could be the
function entry address) value and the adjusted st_value. So that it is
easy to resolve and match either function descriptors and/or function
entry addresses.
Since these new functions also return more information they replace the
dwfl_module_getsym_elf and dwfl_module_addrsym_elf functions that never
made it into a released elfutils version.
addr2line and readelf now use the new functions when looking up functions
names. addr2line will now also display the section the address was found
in when given -x.
Extra testcases were added for both addr2line and the dwflsyms testscase.

Introduce two new functions that also return the elf associated with a

directly. Document limitations of shndx with existing dwfl_module_addrsym
