* generic/tclUnicodeObj.c: Lots of cleanup and simplification.

Fixed several memory bugs.  Added TclAppendUnicodeToObj.

* generic/tclInt.h: Added declarations for various Unicode string
functions.

* generic/tclRegexp.c:
* generic/tclCmdMZ.c: Changed to use new Unicode string interfaces
for better performance.

* generic/tclRegexp.h:
* generic/tclRegexp.c:
* generic/tcl.h:
* generic/tcl.decls: Added Tcl_RegExpMatchObj and
Tcl_RegExpGetInfo calls to access lower level regexp API.  These
features are needed by Expect.  This is a preliminary
implementation pending final review and cleanup.

* generic/tclCmdMZ.c:
* tests/string.test: Fixed bug where string map failed on null
strings.
