[svn-r15549] Description:

	Initial checkin of extensible array data structure prototype code and
regression tests.

	Initial definitions for revised FUNC_ENTER/LEAVE and error reporting
macros, which are being vetted in the extensible array code.

	Minor warning and formatting cleanups in other sections of code.

Tested on:
        Mac OS X/32 10.5.4 (amazon) in debug mode
        Mac OS X/32 10.5.4 (amazon) w/C++ & FORTRAN, w/threadsafe,
