Artiq assumes that all exceptions raised by the kernel can be constructed with
a single string argument. This isn't always the case. Especially for
exceptions that originated in python and were propagated to the kernel over
rpc.
With out this change a mosek solver failure looks like:
```
ERROR root:logging_tools.py:41 Terminating with exception (TypeError: __init__() missing 1 required positional argument: 'msg')

When serialising a list of objects `_send_rpc_value` makes a copy of the
upcoming tags to pass repeatedly to the recursive call. Then uses
`_skip_rpc_value` to skip over the tags that should have been processed.
This didn't handle numpy arrays so, after processing a list of arrays it
got out of sync and failed.

Remove the implementation of setting keepalive settings on sockets and use
the implementation from sipyco instead.

* init() now also clear and resets more state including the interpolators.
If not done, this PLL unlocks/locks may lead to random interpolator state
on boot to which the CICs react badly.
* Use and expose `t_frame`
* Clarify implementation state of `read()`
Exception name is replaced by exception ID, which requires no
allocation. Other strings in the exception can now be 'host-only'
strings, which is represented by a CSlice with len = usize::MAX and
ptr = key, to avoid the need for allocation when raising exceptions
through RPC.
