+ further improve ifdef in term_entry.h for internal definitions not

+ add smso for env230, to match sgr -TD
+ remove p7/protect from sgr in fbterm -TD
+ drop setf/setb from fbterm; setaf/setab are enough -TD
+ make xterm-pcolor sgr consistent with other capabilities -TD

(discussion with Nicholas Marriott)
+ add test-programs sp_tinfo and extended_color
+ modify no-leaks code for lib_cur_term.c to account for the tgetent()
cache.

works as expected. Also modify _nc_setupscreen() to avoid redundant
calls to get original tty-modes.
+ modify set_curterm() to update ttytype[] data used by longname().
+ modify wattr_set() and wattr_get() to return ERR if win-parameter is
null, as documented.
+ improve cast used for null-pointer checks in header macros, to
reduce compiler warnings.
