+ + fix a null-pointer check in _nc_format_slks() in lib_slk.c, from
+ 20070704 changes.
+ + modify _nc_find_type_entry() to use hashing.
+ + make CCHARW_MAX value configurable, noting that changing this would
+ change the size of cchar_t, and would be ABI-incompatible.
+ + modify test-programs, e.g,. test/view.c, to address subtle
+ differences between Tru64/Solaris and HPUX/AIX getcchar() return
+ values.
+ + modify length returned by getcchar() to count the trailing null
+ which is documented in X/Open (cf: 20020427).
+ + fixes for test programs to build/work on HPUX and AIX, etc.
+
+20090711
+ + improve performance of tigetstr, etc., by using hashing code from tic.
+ + minor fixes for memory-leak checking.
+ + add test/demo_terminfo, for comparison with demo_termcap

+ + remove wide-character checks from unctrl() (patch by Clemens Ladisch).
+ + revise wadd_wch() and wecho_wchar() to eliminate dependency on
+ unctrl().
