8c862c4eea Only write to remote socket when we know they are writable 
Buffer data (in an horribly innefficient way for now), and use the
event manager to watch for the socket being ready for a write.

95c1528342 Fix crash when a client sends a packet advertising a wrong size 
If the given size is less than the header size, the message is
clearly invalid, disconnect the client in that case.

3a81260917 Simplify greatly UI input handling 
This round trip through an input callback expected to call
is_key_available and get_key was overcomplicated, just send the
keys as they arrive, the client is already buffering due to urgent
event mode.

f904402486 Handle all available keys when a RemoteClient input is available 
We were just treating the next key. Which led to <esc> byte
remaining after suspend, that led that <esc> being interpretted
as <alt> when the following key got available.

35559b65dd Support codepoints of variable width 
Add a ColumnCount type and use it in place of CharCount whenever
more appropriate, take column size of codepoints into account for
vertical movements and docstring wrapping.

Maxime Coste
4fc20b8d7d Rework client quitting and handling of remote errors 
Client quitting no longer immediately unwinds, client is just pushed
for deletion until we get back to the main loop, similarly to what
happens for buffer and window deletion.

563497ade7 Use proper buffering when reading remote messages 
Messages now have their size in a header, along with their type
and are only executed once fully received. We dont block anymore
while trying to read a full message.

044a6ce860 Rework binary network protocol to be more message based 
We cannot just write to Kakoune socket from any application anymore,
use of kak -p is mandatory, as we now have an introduction to write.
