mwojcik eb57b3b393 drtio: async messages become synchronous 
They are now a reply for DestinationStatusRequest.
This prevents gateware errors and lost packets if the receiver is busy.

Egor Savkin 8984f5104a Move RTIO errors formatting to the session_proto 
This would be closer to the artiq-zynq implementation

Michael Birtwell 671453938b Require explicitly closing TcpStreams 
Instead of automatically closing and draining the TcpStream in the Drop
implementation instead expect the user to call TcpStream::close.
Add close called to all users of TcpStream.
Document the requirement to call close on TcpListener::accept, this seems
to be the only way to get a new TcpStream at the moment.

pca006132 4132c450a5 firmware: runtime changes for exception 
Ported from:
M-Labs/artiq-zynq#162

This includes new API for exception handling, some refactoring to avoid
code duplication for exception structures, and modified protocols to
send nested exceptions and avoid string allocation.

whitequark 0edae64afb firmware: fix TOCTTOU race in sync/async RPC code. 
Before this commit, the main loop in session code was laid like:

  1. process_kern_queued_rpc
  2. process_host_message
  3. process_kern_message

If a host message (such as an RPC reply) caused the kernel to exit,
then any async RPCs would not complete, since RunFinished immediately
shuts down the kernel.

Fix this by reordering 1 and 2.

whitequark 9347f6e00c firmware: use a dedicated error type in the scheduler. 
After this commit, error handling does not normally allocate
(session::Error::{Load,Unexpected} still allocate, but those two
are very rare).

Good riddance to libstd_artiq.
