Dodji Seketeli 322b0e7769 Expose a new libabigail::tools_utils namespace
The utilities present in this namespace were previously living in
tools/abg-tools-utils.h and tools/abg-tools-utils.cc.  They were not
exported and were meant to be useful to the tools writting in the
tools/ directory.  I realized that these utilities might be useful to
clients of the libabigail library in general so I am making them
available generally.  Note that the initial name of the namespace was
libabigail::tools; so renaming it to libabigail::tools_utils required
that I adjust some client code.  I have also cleaned up the code,
interfaces and their apidoc a little bit.

	* include/abg-tools-utils.h: Moved tools/abg-tools-utils.h in
	here.  Renamed the namespace tools into tools_utils.  Inject
	std::ostream, std::istream, std::ifstream, and std::string types
	into the tools_utils namespace.  Adjust the function declarations
	accordingly.  Remove the useless dirname() function declaration.
	* include/Makefile.am: Add abg-tools-utils.h to the list of
	exported headers.
	* src/abg-tools-utils.cc: Moved tools/abg-tools-utils.cc in here.
	Renamed the namespace tools into tools_utils.
	(get_stat): Add apidoc.
	(is_dir): Cleanup apidoc.
	(dir_name); Cleanup parameter name.
	(guess_file_type): Cleanup parameter type.
	* src/Makefile.am: Add abg-tools-utils.cc to the list of exported
	headers.
	* tools/Makefile.am: Do not build the temporary library
	libtoolsutils.la anymore as abg-tools-utils.{h,cc} have moved out
	of this directory.
	* tools/abicompat.cc (parse_command_line, main): Adjust for tools
	-> tools_utils namespace change.
	* tools/abidiff.cc (parse_command_line, main): Likewise.
	* tools/abidw.cc (parse_command_line, main): Likewise.
	* tools/abilint.cc (parse_command_line, main): Likewise.
	* tests/test-abicompat.cc (main): Adjust for tools -> tools_utils
	namespace change.
	* tests/test-abidiff.cc (main): Likewise.
	* tests/test-alt-dwarf-file.cc (main): Likewise.
	* tests/test-core-diff.cc (main): Likewise.
	* tests/test-diff-dwarf.cc (main): Likewise.
	* tests/test-diff-filter.cc (main): Likewise.
	* tests/test-diff-suppr.cc (main): Likewise.
	* tests/test-lookup-syms.cc (main): Likewise.
	* tests/test-read-dwarf.cc (main): Likewise.
	* tests/test-read-write.cc (main): Likewise.
	* tests/Makefile.am: Do not reference the libtoolsutils.la private
	library anymore.
