7a4eefe87c Add support for multiple charset definitions
vt100 has support for two defined charset, G0 and G1. Each charset
can be defined, but in each moment is selected only one of both
charset. This is usually used selecting a national charset in G0
and graphic charset in G1, so you can switch between graphic
charset and text charset without losing the national charset
already defined.

st hasn't support for national charsets, because it is an utf8
based terminal emulator, but it has support for graphic
charset because it is heavily used, but it only supports G0,
without understanding G1 selection sequences, which causes some
programs in some moments can print some garbage in the screen.

This patch adds a fake support for multiple charset definitions,
where we only support graphic charset and us-ascii charset, but
we allow more of one charset definition.

This patch allow define G0 until G3 charsets, but only accepts
select G0 or G1, and it accepts some national charset definitions
but all of them are mapped to us-ascii.

62ab938965 Fix save/restore cursor
st was assuming that save/restore cursor position was independent
of the screen that was shown in each moment, but it is not true,
because each screen has a different save/restore buffer. This
patch fixes it.

eeae9b0cee Fix core in multi-line selection on OpenBSD
OpenBSD 5.3 amd64 release version with the most current st
version from git, crash and dump core when selecting multiple
lines whith the cursor.  This happens, because on line 964
of st.c (gp-1)->mode is accessed, although gp is still
pointing at the beginning of the array term.line[y] (see
line 939 for initialization of gp).

8ac0a5f872 Add bracketed paste mode
This patch enables bracketed paste mode (
http://invisible-island.net/xterm/ctlseqs/ctlseqs.html#Bracketed%20Paste%20Mode
).

It's mainly useful for text editors to disable line wrapping and auto
indentation when text is being pasted, rather than typed from keyboard.

On the emulator side, it is supported by at least xterm, urxvt,
gnome-terminal, putty, iterm2; and I have a patch for konsole.

On the application side, vim can be configured easily to handle this, and
I have pending patches for mcedit and joe. Probably many others also
support it.

eae31a532e Fix some bugs in mouse tracking logic
* Button number in X10 mode:

  I believe the button - 1 came from "C b is button - 1" from [0].
  However, above this section, it states

    "Normally, parameters (such as pointer poisition and button number)
     for all mouse tracking escape sequences generated by xterm encode
     numeric parameters in a single character as value+32. For example, !
     specifies the value 1."

  Also, from the description of SGR,

    "The encoded button value in this case does not add 32 since that
     was useful only in the X10 scheme for ensuring that the byte
     containing the button value is a printable code."

  This suggests that we should still add 32 to the button value when in
  MODE_MOUSEX10.

* No button release reporting in X10 mode:

    "X10 compatibility mode sends an escape sequence only on button press,
     encoding the location and the mouse button pressed."

* Fix MODE_MOUSEMOTION:

  Currently, motion reporting is skipped when oldbutton == 3
  (corresponding to no button being pressed). However, oldbutton is
  only set on a button press, which will never be 3.

4245ba0d12 Correctly initialize altscreen when defaultbg is not 0.
The alternate screen is not properly initialized when st starts. To see
this, set defaultbg in config.h to anything other than 0 (for example, swap
defaultfg and defaultbg), and run:

./st -e sh -c 'tput smcup; read'

You should see that the top-left 80x24 rectangle is black (or whatever
colorname[0] is), while the rest of the screen (if any) has the desired
colorname[defaultbg] color.

The attached patch fixes this by initializing term.c.attr in tnew() before
calling tresize(). It also removes the unnecessary xcalloc() calls, which
misled me on this bug hunt since it is really tclearregion() which
initializes term.lines and term.alt in tresize().

f3d438b101 Regarding commit 7e3cff3
Hello.

I reviewed and tested commit 7e3cff3, and made a patch that fixes some
problems in it.

1. There's a semicolon after an if statement, which is obviously a
typo.

2. The current way of calculating text position in "xdraws" yields
inconsistent results in some cases. This is due to the use of
"font->width", which varies. Instead, "xw.cw" has to be used as the
character width.

Sincerely,
Eon

4579693818 Add terminfo definitions for terminals with meta key
Some programs don't check the value of km and use smm and rmm
capabilites, and they cause the terminal change to meta enabled
mode even in cases where is not desirable.

Allmost all people is using the terminal waiting that meta sends
escape, so rmm and smm are not needed. If someone needs meta
sets 8 bit he can use the correct terminfo definition in TERM.

aaee0e8b28 Reload colors in reset
Colors definition can be changed using a OSC sequence, so
we have to reload them if we want be sure all the colors
are the correct.

Could be desirable free the colors allocated due to rgb
colors and inverse colors (XftColorAllocValues in xdraws),
but it is impossible due we use the same structure for all
of them.

33ad83d492 Improved font caching
I made a patch that improves the performance of font caching mechanism.
This is based on a funny behaviour of FontConfig: it was handling
FcCharSet in a somewhat unexpected way.

So, we are currently adding "a character" to a new FcCharSet, and then
add it to a FcPattern. However, if we toss the FcPattern to FontConfig,
it loads the entire language(charset) that contains the character we
gave. That is, we don't always have to load a new font for each unknown
character. Instead, we can reused cached fonts, and this significantly
reduces the number of calls to extremely slow FontConfig matching
functions.

One more thing. I found that, in libXft, there's a function called
XftCharExists. XftCharIndex internally calls this function, and
does more stuffs if the character does exist. Since the returned index
is never used in st, we should call XftCharExists instead of
XftCharIndex. Please note that I already made this change in the patch.

6e1c7c8afc Fix match function bugs
There were two problems with match denfinition.

1) There was a forward declaration in the form:

	static inline bool match(uint, uint);

but later the function was defined as:

	inline bool
	match(uint mask, uint state) {

This causes that there were two different functions in the code, one local
and inline, and other inline but extern. All was working without problems
due to we were using -Os, and the compiler was using the extern definition
and it was no expanding the static declaration. If you removed the -Os flag,
then you got linker errors due it was no able to find the static definition
of the static declaration.

2) The mask checking was incorrect because we were doing the test:

	(state & mask) != state

and this test only was saying that at least all the enabled bits of state
were enabled also in mask, but no all the possible bits in mask. This was
the origin of the bug reported by Xavier Cartron, where he said it was
possible activated some shortcuts with some of the modifiers defined in the
config.h file.

ebbac77d74 Fix selection clearing
The way st knows if there is a selection activated is checking if sel.ob.x
is equal to -1. In some parts of the code the way of disabling the selection
was only setting it to -1, but after it you can't be sure if the selection
is clearing from the terminal representation, because it is necessary mark
all the lines affected by the selection as dirty. Already there is a functon
which perform this task, selclear.
