this fixes a crash due to illegal memory access that can occur if
something is printed to the screen on the "terminal resized"
handler. It is not clear to me whether this race condition can be
triggered by external incoming messages, but it might be better safe
than sorry.
the colour 0 was broken by the extended colours patch because it needs
an explicit bit check (lower bits will be false since it is 0)
Thanks to lhynes for the report
Fixes Github issue #97https://github.com/irssi/irssi/issues/97
Fix proposed by ailin-nemui, built and tested on Debian Jessie using
0.8.15 source, tested by GeertHauwaerts as well.
It's tricky to make the banner show first in all cases and it's unlikely
to be seen if someone is connecting to a server already, so just don't
show it.
256 colour patch is cleaned up and the remaining cases are made work,
this includes especially Theme support, which was not implemented
before. Changes not related to colours were reverted again, making a
review of the two patches against master easier to follow.
As a byproduct of the Hex-colour code parser, the 24bit colours are
also implemented. Actually using them in the terminal is guarded by a
compile time switch (as well as a run time switch), as it breaks the
existing colour protocol and requires additional storage.
To make a seamless usage, down-conversion is provided for 8 and 16
colours.
Diverging from Tom's approach, the colour protocol is reverted back to
the original one. Unfortunately, the changes required in the Theme
engine will break the API.

This patch implements some 256 colour support for Irssi up from the
previous 16 colours. Initial parsing of the %x/%X format codes is
implemented and the parser accounts in advances the char* for
that.
The colour attributes are widened from 4 to 8 bit. The colour protocol
is changed to a new format. Some pointers to remaining work are
written in the comment in textbuffer.h.
Note that Irssi already does support requesting 256 colours from the
terminal in the original source code, so this part did not have to be
touched.
The crash can happen if the terminal height decreases before the first window
is created. Based on a patch by Jaroslav Škarvada (red hat bug #796457).

subsequent reads are associated to the same paste if they happen before
'paste_detect_time' time since the last read. If no read occurs after
'paste_detect_time' time the paste buffer is flushed; if there is at least one
complete line its content is sent as a paste, otherwise it is processed
normally.
Thanks to Emanuele Giaquinta.
