Uncovered by Uros Bizjak.
Before this patch the test would close the file descriptor but
not the os.File. When the os.File was GC'ed, the finalizer
would close the file descriptor again. That would cause
problems if the same file descriptor were returned by a later
call to open in another test.
On my system:

Avoid conservative behavior in REE by allowing removal of redundant extends
when the def feeds another extend with a different mode. This works because
in merge_def_and_ext only calls combine_set_extension if the candidate for
removal has a wider mode than the def extend's mode, otherwise the def extend
mode is preserved. In combine_set_extension the def is modified to use the
wider candidate's mode.

Change hash_table to support a comparator type different from the
value type stored in the hash table. The 'find' functions now may
take a different type from the value type. This requires introducing
a second typedef into the Descriptor conceptual type. Change the
Descriptor concept to use typedefs value_type and compare_type instead
of T. Change all users to match.
Add usage documentation to hash-table.h.
Tested on x86-64.
