gold/
* gold.cc (queue_final_tasks): invoke layout->queue_build_id_tasks().
* layout.cc (Hash_task): New class.
(Layout::queue_build_id_tasks): New function.
(Layout::write_build_id): Handle single-thread portion of build ID
computation. (In some cases, all of it is single-threaded.) Replace
{sha1,md5}_process_bytes with {sha1,md5}_buffer to get the same
functionality in fewer lines of code.
* layout.h (Layout::queue_build_id_tasks): New function declaration.
* options.h (General_options): make "--build-id" default to tree
rather than sha1. Add two new options related to --build-id=tree:
--build-id-chunk-size-for-treehash and
--build-id-min-file-size-for-treehash.
* Makefile.am: add testing of --build-id=tree and related new options
(these tests will be invoked by "make check").
* Makefile.in: Regenerate.
