server/client: harden reading of initialization data, and make async
...
* Client terminal initialization data is now received
asynchronously. To facilitate this, a couple of minor changes to the
protocol was made:
- The client now starts with sending a 4-byte unsigned integer
with the *total* size of the initialization data (*not*
including the size field itself.
- Strings (TERM variable + argv) are now sent NULL-terminated
* The server allocates a single buffer, and fills it
asynchronously. When full (as indicated by the initial 'total size'
integer), we parse it (taking care not to read outside boundaries
etc, and verifies the lengths (of the TERM variable and argv array)
indicated by the client matches the actual lengths of the strings
received.
* The server now ignores 'unexpected' data received from the client,
after the terminal has been instantiated.

If the clients attempt to send more data after we've instantiated the
terminal, just consume the data but ignore it.

terminal: trim memory after free:ing a terminal
...
A terminal with lots of scrollback history will have allocated a lot
of memory.
Normally, free() wont return this memory to the OS, and we don't seem
to trigger the automatic trim calls.
This means the server would accumulate quite a lot of memory over
time, as terminals come and go.
Now we explicitly trim the memory every time a terminal is destroyed.

term: asynchronous writes to slave
...
Make ptmx non-blocking. Then, when writing data to the slave would
have blocked, use the FDM to asynchronously write the remaining data.
This is done by enabling EPOLLOUT on ptmx, and enqueueing all outgoing
data. The FDM handler will go through the enqueued data, and once all
of it has been written, we turn off EPOLLOUT again (thus switching
back to synchronous writes)
