Dodji Seketeli 3c0701d59d Support having several debuginfo search dirs for a binary
There are use cases where the split debuginfo file of a given binary
is under a given root directory and that the split debuginfo file
itself depends on an alternate debuginfo file that is under another
unrelated root directory.

In that case, the dwarf reader must be able to look for the debuginfo
files under several unrelated root directories.  The tools abidiff and
abidw must thus support having several occurences of the option
--debug-info-dir1 (or --debug-info-dir2) meaning that the debuginfo
files for the binary must be looked for under several root
directories.

This is what this patch does.

	* doc/manuals/abidiff.rst: Adjust doc for the
	--debug-info-dir{1,2} that can now be provided several times.
	* include/abg-dwarf-reader.h ({create, reset}_read_context)
	(read_corpus_from_elf): Take a vector of debug info root dirs.
	* include/abg-tools-utils.h (trim_leading_string)
	(find_file_under_dir, make_path_absolute_to_be_freed)
	(convert_char_stars_to_char_star_stars): Declare new functions.
	* src/abg-dwarf-reader.cc (find_alt_debug_info_link): Renamed
	find_alt_debug_info_location into this.
	(find_alt_debug_info_path): Define new static function.
	(find_alt_debug_info): Take a vector of debug info root dirs.  Use
	the new find_alt_debug_info_path to look into the debug info root
	dirs for the alt debug info.
	(read_context::debug_info_root_paths_): Define new data member.
	(read_context::read_context): Take a vector of debug info root
	dirs and initialize the new read_context::debug_info_root_paths_.
	(read_context::{initialize, create_default_dwfl}): Take a vector
	of debug info root dirs and adjust.
	(read_context::{add_debug_info_root_paths,
	add_debug_info_root_path, find_alt_debug_info}): Define new member
	functions.
	(read_context::load_debug_info): Look into the debug info roots
	for split debug info files.
	(create_read_context, read_corpus_from_elf): Take a vector of
	debug info root dirs and adjust.
	(has_alt_debug_info): Adjust.
	* src/abg-tools-utils.cc (trim_leading_string)
	(make_path_absolute_to_be_freed, find_file_under_dir)
	(convert_char_stars_to_char_star_stars): Define new functions.
	(entry_of_file_with_name): Define new static function.
	(build_corpus_group_from_kernel_dist_under): Adjust.
	* tests/print-diff-tree.cc (main): Adjust.
	* tests/test-diff-dwarf.cc (main): Adjust.
	* tests/test-ir-walker.cc (main): Adjust.
	* tests/test-read-dwarf.cc (main): Adjust.
	* tools/abicompat.cc (main): Adjust.
	* tools/abidiff.cc (options::di_root_paths{1,2}): Changed
	di_root_path{1,2} into this, change their types into vectors of
	allocated char*.
	(options::prepared_di_root_paths{1,2}): Define new data members.
	(options::~options): Define new destructor.
	(parse_command_line): Adjust.
	(prepare_di_root_paths): Define new static function.
	(handle_error): Remove arguments input_file_name,
	debug_info_dir{1,2}.  Now just take an instance of options
	instead.  Adjust.
	(main): Adjust.
	* tools/abidw.cc (options::dir_root_paths): Renamed dir_root_path
	into this and make it be a vector of allocated char*.
	(options::prepared_di_root_paths): Define new data member.
	(options::~options): Free the allocated char* in
	options::dir_root_paths.
	(parse_command_line): Support several --debug-info-dir.
	(load_corpus_and_write_abixml): Adjust.
	(prepare_di_root_paths): Define static function.
	(main): Adjust.
	* tools/abilint.cc (main): Adjust.
	* tools/abipkgdiff.cc (compare): Adjust.
