Robert Jördens 2de1eaa521 dashboard: reconnect to core moninj
* 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

David Nadlinger ef934ad958 Add test/release notes for command-less controllers

Chris Ballance eaa1b44b00 ctlmgr: ignore controllers without a "command" field
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.

whitequark d6eb2b023a compiler: monomorphize casts first, but more carefully.
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.

David Nadlinger 0da799fa46 conda: Require recent aiohttp
artiq_influxdb doesn't work with aiohttp 0.17 (anymore), as the
ClientSession API changed. I have not looked up precisely which
is the first version that works, but 3.x has been out for almost
a year and is available on the Anaconda/conda-forge channels.

Sebastien Bourdeauducq ec230d6560 sayma: move SYSREF DDMTD to the RTM
Put RTM Si5324 into bypass mode before running.
Needs rework to cut RTM Si5324 reset trace.
Needs rework to fix LVDS termination on RTM R310/R313 and R314/R315.
Needs uFL jumper cables between RTM "REF LO DIAG" and "CRD AUX CLKIN" (sic).

Sebastien Bourdeauducq 8119000982 sayma_rtm_drtio: use Si5324 soft reset
Needs easy board rework to cut trace at pin 1 of Si5324.
The Si5324 contains an internal pull-up on that pin.

Allows using Si5324 + HMC7043 chips at the same time.

Allows the Si5324 bypass hack for DDMTD experiments on the RTM.
