Log Message:
Update to version 9.22.

Changes:
- NOTICE: this release updates terminfo.
- add terminfo capabilities for various ctrl and shift-ctrl key variants
  (patch by Sebastian Schmidt).
- fix longstanding core font encoding bug where some character
  ranges could not be mapped from unicode to the font: affected
  encodings are big5, gb2312, iso8859-8 (hebrew), jis0201 and
  ksc5601 (reported by Mikachu).
- fix crash when the number of columns is 1 and a 0 width character is inserted
  (reported by Kuang-che Wu).
- fix a crash when parsing an invalid color specification (reported by Kuang-che Wu).
- fix a buffer overflow in font name parser (reported by Kuang-che Wu).
- do not start blinking cursor if the window is unfocused (reported by
  Devin J. Pohly).
- change the width of underline and i-beam cursor to 2 pixels (based on
  a patch by Omar Sandoval).
- add pointerShape resource to change the mouse pointer shape
  (based on a patch by Brian Watson).
- a keysym resource for a key which is already bound to an
  action now properly rebinds the key.
- do not report mouse motion events if Shift is active (patch by Daniel Hahler).
- put the alpha component last in responses to OSC color queries
  (patch by Benjamin Herr).
- the key_press hook is now invoked before processing the
  event, as documented. This change was done in 9.21 but not
  announced and fixes debian bugs #511377, #531751 and red hat
  bug #1105069. Note that this change breaks a few scripts,
  such as mark-yank-urls, which rely on the previous buggy
  behaviour that urxvt processes the event (in particular
  keysym bindings) before invoking the hook.
- the tabbed extension now properly refreshes the active tab
  on a key press when the mouse pointer is outside the terminal
  window.
- add 'lookup_keysym' perl method to lookup the action bound
  to a key combination.
- a key combination bound to 'matcher:select' can now be used
  to cycle through the matches in matcher.
- change perl integer accessors (->width et al.) into mutators.
