[test] apple-dylan-test-suite: Add some missing classes in
limited-collections-1 test.
Remove locking on stream while formatting.

By default, streams create a lock when they're created. This lock
is then used to synchronize access to the stream in various situations.

Even when contention on a given stream isn't high, this lock can
have some impact on performance due to creating contention on a
lock within the Boehm GC when using the C backend. This is because
the lock's constructor registers a finalizer, which grabs the GC
lock.

When we're formatting to a string or formatting a date, we know
that other threads won't be using this internal string-stream, so
we can disable locking on it safely.

This provides a substantial performance improvement to the HTTP
server under load.
Merge pull request #458 from waywardmonkeys/reduce-locking-on-streams

Remove locking on stream while formatting.
Remove unused binding todays-dispatch-report.

This hasn't done anything in years and was marked as temporary.
Clean up whitespace.
Merge pull request #457 from abeaumont/master

[test] apple-dylan-test-suite: Add some missing classes in limited-collections-1 test.
Cleanup whitespace in dispatch code.
[test] apple-dylan-test-suite: Add missing classes to limited-collections-2
and limited-collections-3 tests. Related to #457.
Merge pull request #459 from abeaumont/master

Add missing classes to limited-collections-2 and limited-collection-3 tests.
Remove patchable-constant macro.
Cleanup whitespace.
Use 'define function'.

A lot of older code used 'define constant' with a method literal
as the code probably pre-dated support for 'define function'.
Use ignore() on unused values.
Fix spelling of propagate.
Cleanup whitespace.
[doc] Begin documenting method dispatch.
Fold handle-missed-dispatch-1 into handle-missed-dispatch.

The code being removed that was commented out has been commented
out since it was originally added in the late 1990s and the
functions that it calls don't actually exist anywhere.
[doc,hackers] Additional method dispatch detail.
[doc,hackers] Fix indentation in build sys docs.
