d5994b43ca Add support for End key
- Shift + End : Delete until end of line.
    - Control + End : Delete until end of screen.

When  the End  key is  pressed  without any  modifier is  not generated  the
correct sequence for it  (going to the end of the  screen), because the size
of the  terminal is not known,  so it is  not possible write a  sequence for
this purpouse.

3c99be68e8 Add support for insert key
Insert key stands for a key which allows enter or leaves insert mode, so let
it generates the correct sequence to change between these modes:

   - Insert: Enter in insert mode.
   - Shift + Insert: Leave insert mode (replace mode).
   - Control + Insert: Insert a blank line.

Like Shift + Insert also paste text, if a user want this feature be full
functional he has to modify such shortcut.

172f65436c Add key for toogling numlock handling
Keypad will generate keycodes when keypad application mode is enabled. It
can cause problems with some programs like vi, which operates in such
mode.

This patch change by default don't generate the keycodes never, but this
behaviour can be changed using the combination Alt + NumLock.

55087ec2c7 Add application cursor sequences for Home
The commit 'Fixing some key issues with mc' fix the problem where mc didn't
recognize home key because the generated code and the terminfo entry were
different (terminfo khome = \E[1~ but generates \033[H).

Home key in ansi mode should generate the sequence CUP (\033[H) to 0,0 (home
position), but it is also interesting generate a application code which
identifies the key. Real vt520 only generates the ansi sequence CUP, linux
console generates only the application code \033[1~, xterm generates CUP in
ansi mode and \033OH in cursor application mode, rxvt only generates the
application code \033[7~.

This patch sets CUP in ansi mode and \033[1~ in cursor application mode, so
it can be used in both modes and the application mode value is similar to
near values (insert = \033[2~, Prior = \033[5~, Next = \033[6~, End =
\033[4~, Supr = \033[3).

4389f2eb1b Use XK_ANY_MOD instead of XK_NO_MOD in key definition
Usually terminal emulators don't generate any sequence for a combination
they don't have registered, for example Shift + Next, but st behavior
previous to the keyboard patch generates the sequence without the modifier,
in this example Next. This patch uses the XK_ANY_MOD in order to get this
same behaviour.

88bb76c1bc Fix XK_NO_MOD and XK_ANY_MOD behavior
XK_NO_MOD match a key without modifiers and XK_ANY_MOD match a key does not
matter what modifiers are pressed to. Like they are mask the best value for
XK_ANY_MOD is all the bits to 1, so the and with any state will be equal to
the state. This also imply that is necessary check the case for XK_NO_MOD
(no modifiers at all) with some modifier in state, and the inverse
(some mask different to XK_ANY_MOD or XK_NO_MOD and no modifiers in state).

620e3bb39e Add missed key definitions
This patch adds the keys for the keypad (in both modes, application mode or
ansi mode) and function keys. It uses the same convention than xterm and
instead of using the XK_Fxx values it generates them using F1-F12 and
modifiers. For example:

   F1 -> ^[OP
   F1 + Shift = F13 -> ^[[1;2P
   F1 + Control = F25 -> ^[[1;5P
   F1 + Mod2 = F37 -> ^[[1;6P
   F1 + Mod1 = F49 -> ^[[1;3P
   F1 + Mod3 = F61 -> ^[[1;4P

It is also important notice than the terminfo capability kIC (shifted insert
key) only can be generated using the keypad keyboard, because the shorcut
for selection paste is using the same combination.

After this path the number of elements in the Key array becomes high, and
maybe a sequencial search is not enough efficient now.

44597b359e Add control and meta combinations for arrow keys
Since there isn't any terminfo capability for control and meta modifiers for
arrows keys it is necessary use the same that almost terminal emulators use,
because there are a lot of programs which have these codes hardcoded.

This cause also that shift combinations are also changed, but in this case
this is not a problem since there are terminfo capabilities for them. After
this patch shift-up and shift-down continue not working in emacs with
TERM=st, but they work with TERM=xterm, so it is possible some other changes
are necessary in the terminfo entry.

3b16695f4e Fix arrow keys terminfo capabilities
Usually the arrow keys generate the ANSI sequence which terminal will
understand like a movement, so it is not necessary any dealing for them, the
program can not know if the sequence is generate for a echo key or directly
from the program. If you need really know if the key was pressed then you
need activate the keypad mode where the keys will generate a special code
for each keypad key.

The terminfo capabilities kcub1, kcud1, kcuf1 and kcuu1 are used for this
keypad code, not for the sequence generate in the ansi mode.

69ee3ba3a7 Fix keypad mode and cursor mode
Keypad mode is used for detecting when keys in the auxiliary keypad are
pressed, while cursor mode is used for detecting when a cursor is pressed,
but they are different modes.

St was mixing both modes and DECPAM and DECPNM modified the cursor mode, and
this was incorrect.

950ff21e17 Fix bug restoring cursor position
Sequences like DECSC, DECRC, ESC [?1047l or ESC [?1047h save and restore
cursor attributes, than taken from vt100 manual are:

       Save Cursor (DECSC) ESC   7
       ===========================
       Saves the following in terminal memory.

      - cursor position
      - graphic rendition
      - character set shift state
      - state of wrap flag
      - state of origin mode

      Restore Cursor (DECRC) ESC 8
      ===========================
      Restores the states described for (DECSC) above. If none of these
      characteristics were saved, the cursor moves to home position; origin
      mode is reset; no character attributes are assigned; and the default
      character set mapping is established.

This implies that hide attribute of the cursor should not be saved/restored
in these sequences. The best way to fix this problem is moving hide
attribute into the terminal mode, instead of having it in the cursor state.
