This helps debugging the cause of TypeErrors arising from types
not handled by the HDF5 serializer, as the backtrace doesn't
otherwise include any useful information.
This simplifies the code and avoids multiplication of cargo versions.
This installs cargo 1.27, but it is compatible enough with artiq rustc
1.28 not to cause any problems for our purposes.
* handle disconnects like core device address changes and do a
disconnect/connect iteration
* after connection failure wait 10 seconds and try again
* this addresses the slight regression from release-2
to release-3 where the moninj protocol was made stateful
(#838 and #1125)
* it would be much better to fix smoltcp/runtime to no loose the
connection under pressure (#1125)
* the crashes reported in #838 look more like a race condition
* master disconnects still require dashboard restarts

Allow controllers to be specified without a "command" field. The user takes
responsibility for ensuring the controller is running: the controller manager
does not attempt to ping the controller. This is useful when one has a common
controller shared between several masters.
This reverts 425cd7851, which broke the use of casts to define
integer width.
Instead of it, two steps are taken:
* First, literals are monomorphized, leading to predictable result.
* Second, casts are monomorphized, in a top-bottom way. I.e.
consider the expression `int64(round(x))`. If round() was visited
first, the intermediate precision would be 32-bit, which is
clearly undesirable. Therefore, contextual rules should take
priority over non-contextual ones.
Fixes#1252.
