69440d19b7 Do not use evbuffer_add_buffer because it is destructive and doesn't 
work in newer libevent.

7bcc0d16f2 Add an argument to copy commands to set the prefix for the buffer name, 
allows buffers for different sessions to be named separately.

13f9a061ac Add a wrapper (struct style) around styles rather than using the 
grid_cell directly. There will be some non-cell members soon.

938156d73b DECRC and DECSC apparently need to preserve origin mode as well, based

3f6bfbaf2b Allow multiple modes to be open in a pane. A stack of open modes is kept 
and the previous restored when the top is exited. If a mode that is
already on the stack is entered, the existing instance is moved to the
top as the active mode rather than being opened new.

same mechanism to get the clipboard from the terminal outside
tmux. GitHub issue 1477.

051a29ca03 A couple of fixes to the : form of SGR. Apparently there is an extra 
argument that nobody knew about, so skip that if it exists. Also there
are a bunch of useless optional arguments at the end, so ignore those.

85c48aafff For some reason tmux treats SGR 10 as SGR 0. It has done since the first 
version and I'm not sure why since no other terminal appears to. Change
to just ignore SGR 10 instead.

c5b7faaefc Add a timeout to prevent the sequences which wait for a specific 
terminator (OSC, APC and DCS) waiting forever, which helps to avoid
garbage (cat /dev/random) locking up panes completely. This (and the
last commit) prompted by a discussion with theo.

8149bc3fa6 Be more strict about escape sequences that rename windows or set titles: 
ignore any that not valid UTF-8 outright, and for good measure pass the
result through our UTF-8-aware vis(3).

df3ab87964 Add support for the strikethrough attribute (SGR 9), using the new smxx 
terminfo capability. This means there are now nine attribute bits, so
anything above 0xff uses an extended cell.

82db1fa9e5 There are buggy terminals out there that do not move the cursor to 0,0 
after CSR, so invalidate the cursor position rather than assuming 0,0.

13a0b6bb3f Collect sequences of printable ASCII characters and process them 
together instead of handling them one by one. This is significantly
faster. Sequences are terminated when we reach the end of the line, fill
the internal buffer, or a different character is seen by the input
parser (an escape sequence, or UTF-8).

Rather than writing collected sequences out immediately, hold them until
it is necessary (another screen modification, or we consume all
available data). This means we can discard changes that would have no
effect (for example, lines that would just be scrolled off the screen or
cleared). This reduces the total amount of data we write out to the
terminal - not important for fast terminals, but a big help with slow
(like xterm).

dd0c814779 Implement "all event" (1003) mouse mode but in a way that works. The 
main issue is that if we have two panes, A with 1002 and B with 1003, we
need to set 1003 outside tmux in order to get all the mouse events, but
then we need to suppress the ones that pane A doesn't want. This is easy
in SGR mouse mode, because buttons == 3 is only used for movement events
(for other events the trailing m/M marks a release instead), but in
normal mouse mode we can't tell so easily. So for that, look at the
previous event instead - if it is drag+release as well, then the current
event is a movement event.

4179b42424 Add support for BCE (background colour erase). This makes various escape 
sequences (notable EL and ED but also IL, DL, ICH, DCH) create blank
cells using the current background colour rather than the default
colour.

On modern systems BCE doesn't really have many benefits, but most other
terminals now support it, some (lazy) applications rely on it, and it is
not hard to include now that we have pane background colours anyway.

Mostly written by Sean Haugh.
