Dodji Seketeli f275939df2 Use worker threads pattern to speed up some tests
We are going to need to speed up more and more tests, and coding directly
with libpthread for that can be tedious and bug-prone.  So I devised an
implementation for the worker threads design pattern instead, and used
it to speed up some tests.

	* include/Makefile.am: Add the new abg-workers.h to source
	distribution.
	* include/abg-workers.h: New file.
	* src/Makefile.am: Add the new abg-worker.cc to source
	distribution.
	* src/abg-workers.cc: New file.
	* tests/test-utils.cc: Update copyright.  Make get_src_dir() and
	get_build_dir() return a const char*, as opposed to returning a
	string.  Make that const char reside in thread local storage, so
	that two concurrent threads can safely call these functions in
	parallel, without any race.
	* tests/test-utils.h: Make get_src_dir() and get_build_dir()
	return a const char*, as opposed to returning a string.
	* tests/test-abicompat.cc: Update copyright.  Adjust for
	get_src_dir() and get_build_dir() change.
	* tests/test-abidiff.cc: Likewise.
	* tests/test-alt-dwarf-file.cc: Likewise.
	* tests/test-core-diff.cc: Likewise.
	* tests/test-diff-dwarf-abixml.cc: Likewise.
	* tests/test-diff-dwarf.cc: Likewise.
	* tests/test-diff-pkg.cc: Likewise.
	* tests/test-diff-suppr.cc: Likewise.
	* tests/test-lookup-syms.cc: Likewise.
	* tests/test-read-dwarf.cc: Likewise.
	* tests/test-read-write.cc: Likewise.
	* tests/test-types-stability.cc: Likewise.  Use the new task queue
	type to run these tests in parallel.
	* tests/test-diff-filter.cc: Likewise.
