libdwfl: Fix memory leak in cache_sections.
commit be1778 libdwfl: Fix possible unbounded stack usage in cache_sections.
introduced a memory leak. The refs pointers were copied to the sortrefs
array but never freed. Only the array was freed. Also free the elements.

libdwfl: Check mod is not NULL in check_module.
check_module is called from dwfl_module_relocate_address and from
dwfl_module_address_section. Both could take a NULL Dwfl_Module if
an earlier error had occured. Make check_module return immediately
indicating an issue in that case.

libdwfl: Fix possible unbounded stack usage in cache_sections.
For modules with lots of sections cache_sections could blow up the stack
theoretically. Don't use alloca, but use malloc with explicit free.

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.

Add aliases for elf_getshnum and elf_getshstrndx.
Sun in their implementation messed up the semantics of these functions.
To get back to source code compatibility they asked for a solution.
We simply add aliases for the two affected functions, named
elf_getshdrnum and elf_getshdrstrndx. The semantics remains the
same. Users of the old interfaces receive a warning for now. In
future we might make it impossible to link programs which request
the old interfaces (binary compatibility will of course be maintained).
