Mainly work on some ease of use extras, and some reworking of a few areas that improves the reader throughput.

• Terminal app fix for user input.

• New (bit-mask mask ...) -> val function and
  (bits? val mask ...) -> :t | :nil macro predicate defined to go with the
  (bits) bitmask definition function.

• New (eval-list list [env]) -> list inplace list element evaluation primitive.
  This is making the :repl_eval_list method available at the user level.

• Improvements to the case macro. Lots of new features since this was first
  written !

• New (macrobind) macro.

• New (static-qqp) macro that only does a prebind pass, no static macroexpand !
  GUI UI macros now use this.

• Major tidy up of the lib/asm/vp.inc file. Use of static-q* where possible
  and removal of redundant type conversions.

• Reference counted netid object for temp mailboxes. Create one via
  (mail-mbox) and no need to explicitly free anymore. (free-select) call is
  now gone, and (alloc-select) is replaced by the (task-mboxes) function which
  creates the select list using (task-mbox), for the first entry, and
  (mail-mbox) for the rest.

• Reworked the lib/task/local.inc class. Added a few more options as well as
  tidying up the code. As a result the build times have improved again. Worth
  spending some of this gain on new VP optimisation checks.

• opt-redundant-branch test added to vpopt.inc. This test looks to see if a
  constant based branch is being done when we already loaded a constant into that
  register that we can static eliminate. This can happen with inline code
  embedding, AND as branch instructions are a KILL op for other searches, it's
  worth checking for.

• Rework of the symbol interning system for the entire OS and Lisp engine. Removed
  redundant methods and streamlined the base method used by lisp :read_sym to
  operate directly from the stream buffers without intermediate copies or string
  object churn.

Enjoy
