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.

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).

malloc and realloc are called through xmalloc and xrealloc, so calloc should
be called through xcalloc.

In previous commits draw was removed from all the X events, but I forgot do
it in resize.

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.

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.

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.

It is necessary call to XSync if you want a good tput flash, because in
other way you can not be sure that white screen will be shown.

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.
