Instead of bundling our own copies of Russ's C TAP Harness, start using
source pulled from his git repository using the src/external import
mechanism. Note that we are not currently building the floating
point (is_double) portion of the harness.
In the process of doing so, we also upgrade our test harness to the latest
upstream version, 1.11. This is somewhat problematic, as there have been
some significant code changes since the version bundled with OpenAFS.
Work around these by
*) Referencing the basic.h header as <tests/tap/basic.h>, rather than
just <tap/basic.h>, to match the new upstream layout
*) Changing the include path so that the tests/ directory can be
found within it.

This imports a small subset of Bob Jenkins lookup3.c hash functions
into the opr library. At present we only import the subset of this
that deals with aligned arrays of integers, as this addresses our
immediate need.
It seems likely that if we're interested in a hash function for string
arrays (or other arbitrary data), that more recent functions such like
SpookyHash (from Bob Jenkins, again) or CityHash (from Google) may be
a better solution.
The immediate use case for this is removing the use of the '%' operator
when indexing speed critical hash tables, as well as ensuring fairer
distribution of entries across these tables.
A short set of test cases is also provided

Add an implementation of red/black trees to our runtime library.
This is originally derived from the FreeBSD macro-based rbtree
implementation, but is heavily reworked to not use macros, to improve
legibility, and to favour speed over structure compactness.
A test suite is provided in tests/opr/

Move the header which is installed as opr/queues.h out of util/ and
into the new, top level, opr/ directory. Similarly move the tests out
of the util/ test suite, and into the opr/ tests
