90e1427632 Fix Shift + Insert shortcut
This patch apply the same code for shortcuts that it is used now for defined
keys. So it is possible use now XK_NO_MOD and XK_ANY_MOD for defining shortcuts.

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).

16ccf344de Fix tab key
When Shift + Tab is pressed X server send the event XK_ISO_Left_Tab with
ShiftMask, so this is the entry we need in config.def.h

This patch also revert the previous patch for this issue because it breaks
the keyboard.

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.

HT		011	Move the cursor to the next tab stop,
			or to the right margin if no further tab stops
			are present on the line.

XON		021	Causes terminal to resume transmission.
XOFF		023	Causes terminal to stop transmitted all codes
			except XOFF and XON.
CAN		030	If sent during a control sequence, the sequence is
			immediately terminated and not executed. It also causes

	Control characters (codes \0 to \37 inclusive) are specifically

	as soon as they are encountered by the VT100. The processing of the
	control sequence then continues with the next character received.

eb360e5fd1 Fix bug in tputc writing to io file
If -f options is enabled then tputc() writes all the data to a file. Actual
code assumes that all the strings in 'c' parameters have always 1 byte
length, but this is not always true, because due to utf-8 encoding some
characters can have a diferent length. So it is necessary pass string length
to tputc in order it can call to write() correctly.

b6cfff1625 Clear X window in tsetreset()
tsetreset() is called when it is necessary a full initialization of the
terminal, so it also should clean the full X window and not only the
terminal content. It is necessary change the order of the
initialization in main(), and put xinit before of tnew(), because tnew()
calls to tsetreset(), and  this can cause a call to xreset() with
incorrect values.

4876d6e05b Clean windows display after resizing
Some times the size after a resizing is not an exact multiply of a number of
characters, so redrawn the screen using the lines and columns of the neww
size can cause that some old graphics keep in the screen. Solution is clean
all the windows with the background color.

88a8f85a8a Copy non set positions as spaces
st selection don't insert in the selection position whose value is not
set. This is correct for the positions in the end of the line, but cause
some problems in the beginning. For example echo -e 'a\tb' will print in the
screen:

a	b

but after selecting and copying in some place you get:

ab

because positions from 1 to 7 don't have any value. This patch deals all
positions without value as blank (even at the end of the line).

d81250e5f9 Fix selection bug
After the commit named "Remove timeout in the main loop", selection is not
working in the proper way. After selecting something, press mouse button in
a line outside of selection causes an incorrect highlight. This patch fix
the problem forcing a draw after the press event, but this is only a fast
hack. Real solution means rewriting selection code.

c5a9b799d4 Render only once in each main loop iteration
draw() runs over all lines of the screen and renders only the dirty lines,
this avoids render lines which are not modified since last draw() call. In
this moment the main loop is something like:

     - Wait something to read from file descriptors
     - Read from pseudo tty
     - Call draw() for rending
     - Read X events

This cause the problem that all the X events that have to update the screen
have to call draw() (because draw() is called before of X events handling),
so you can have multiples renderings in only one iteration, that will waste
a lot of resources.

This patch change the main loop to:

     - Wait something to read from file descriptors
     - Read from pseudo tty
     - Read X events
     - Call draw() for rending

So X events don't have to worry about rendering, because draw() is called
after them.

The only place where draw is called outside of the main loop is in redraw(),
but it is necessary for getting a good tput flash.

85849ce72a Remove timeout in the main loop
The main loop waits until there is some data to read in file descriptors of
the X server or the pseudo tty. But it uses a timeout in select(), which
causes that st awake each 20 ms, even it doesn't have something to do. This
patch removes this problem removing the timeout, which is not needed.

ba1e9daeef Call XdbeQueryExtension before of calling any Xdbe function
XdbeQueryExtension() tells to the caller if the Xdbe extension is present in
the X server, so it should be called for sanity. But like is said in
XdbeQueryExtension(3):

	No other Xdbe functions may be called before this function.  If a
	client violates this rule, the effects of all subsequent Xdbe calls
	that it makes are undefined.

it is mandatory call this function.

720cb816dc Remove buffering to fileio instead of calling fflush
By default text files are line buffered, and this means that -f option will
not write the line until a \n is printed. This is not very useful for
debugging, so a call to fflush was added. This patch substitute this call
(which will be done by each character painted) by the full remove of the
buffering in the file.

b9d5fec4f2 Add xmalloc and xrealloc wrappers
If malloc  or realloc fail they return NULL. Theorically this condition
should be tested in the code, but it's a strange condition today (basically
if this is hapenning thenyou have a big problem), and even Linux never returns
NULL in the default configuration (only if the process don't have room in
the space address, something a bit impossible in the case of st). But stis
enough small for being executed in low resources computers where this can be
a real problem. So the easy way is creating a wrappers function for them and
call to die in case of error.

f471a32d29 Unhighlight selection when selection is owner by other window
st marks the active selection using reverse colors in the box selection, but
once that another window becomes owner of the selection, it is very
confusing that st keeps highlight the old selection. Usually terminal
emulators remove the highlight when it is not valid anymore.

X sends a SelectionClear event in this situation, so we only have to add a
callback which unhighlight the selectin box.

98b6f84bfc Check alternative screen before drawing box selection
Some programs use the alternative screen (vi, less, ...), whose
content is different of the main screen. If you select text in one of
the screen, you don't wait the box selection is painted in the other
screen, so it is necessary check if the selection was done in the same
screen we are going to paint. Before to this commit, you could do
something like:

	$ LESS="" ls | less
	(select some code)
	q

and selection box remains drawing in the main screen, but the content
of selection keeps text of the alternate screen.

When it is called DECSCNM all lines become dirty, because it is necessary
redraw all lines for getting the new colors. It is easy see the problem
running 'echo ^[[?5h'.

In order to get a correct flash when running tput flash is necessary wait
after DECSCNM, until the changes are displayed, because in other case the
switch between reverse on/reverse off will be too much fast and nothing will
happen.

* wait at least 20ms (DRAW_TIMEOUT) between draw() calls
* only copy dirty lines from the buffer to the screen

what draw() does:
* clears dirty lines in the buffer
* draws the longest same-attributes string of each

* copies the current dirty line from buffer to the screen with a single
  xcopy() call
