+ update test programs to build/work with various UNIX curses for
comparisons. This was to reinvestigate statement in X/Open curses
that insnstr and winsnstr perform wrapping. None of the Unix-branded
implementations do this, as noted in manpage (cf: 20040228).
+ modify fix_wchnstr() in form library to strip attributes (and color)
from the cchar_t array (field cells) read from a field's window.
Otherwise, when copying the field cells back to the window, the
associated color overrides the field's background color (report by
Ricardo Cantu).
+ improve tracing for form library, showing created forms, fields, etc.
+ ignore --enable-rpath configure option if --with-shared was omitted.
+ add _nc_leaks_tinfo(), _nc_free_tic(), _nc_free_tinfo() entrypoints
to allow leak-checking when both tic- and tinfo-libraries are built.
+ drop CF_CPP_VSCAN_FUNC macro from configure script, since C++ binding
no longer relies on it.
+ disallow combining configure script options --with-ticlib and
--enable-termcap (report by Rong-En Fan).
+ remove tack from ncurses tree.
