ncurses 6.0 - patch 20180121

> terminfo changes:
+ add xterm+noalt, xterm+titlestack, xterm+alt1049, xterm+alt+title
  blocks from xterm #331 -TD
+ add xterm+direct, xterm+indirect, xterm-direct entries from xterm
  #331 -TD
+ modify xterm+256color and xterm+256setaf to use correct number of
  color pairs, for ncurses 6.1 -TD
+ add rs1 capability to xterm-256color -TD
+ modify xterm-r5, xterm-r6 and xterm-xf86-v32 to use xterm+kbs to
  match xterm #272, reflecting packager's changes -TD
+ remove "boolean" Se, Ss from st-0.7 -TD
+ add konsole-direct and st-direct -TD
+ remove unsupported "Tc" capability from st-0.7; use st-direct if
  direct-colors are wanted -TD
+ add vte-direct -TD
+ add XT, hpa, indn, and vpa to screen, and invis, E3 to tmux (patch by
  Pierre Carru)
+ use xterm+sm+1006 in xterm-new, vte-2014 -TD
+ use xterm+x11mouse in iterm, iterm2, mlterm3 because xterm's 1006
  mode does not work with those programs.  konsole is debatable -TD
+ add "termite" entry (report by Markus Pfeiffer) -TD
> merge branch begun April 2, 2017 which provides these features:
+ support read/write new binary-format for terminfo which stores
  numeric capabilities as a signed 32-bit integer.  The test programs
  such as picsmap, ncurses were created or updated during 2017 to use
  this feature.
+ the new format is written by the wide-character configuration of
  tic when it finds a numeric capability larger than 32767.
+ other applications such as infocmp built with the wide-character
  ncurses library work as expected.
+ applications built with the "narrow" (8-bit) configuration will
  read the new format, but will limit those extended values to 32767.
+ in either wide/narrow configuration, the structure defined in
  term.h still uses signed 16-bit values.
+ because it is incompatible with the legacy (mid-1980s) binary format,
  a new magic value is provided for the "file" program.
+ the term.5 manual page is updated to describe this new format.
+ the limit on file-size for compiled terminfo is increased in the
  wide-character configuration to 32768.
