Sebastien Bourdeauducq 8bcba82b65 grabber: reset *_good signals on end of frame 
This reduces the amount of time the ROI engine produces invalid output after
being reconfigured.

David Nadligner 141fcaaa8a worker_db: Only warn on repeated archive read if dataset changed 
In larger experiments, it is quite natural for the same dataset
to be read from multiple unrelated components. The only situation
where multiple reads from an archived dataset are problematic is
when the valeu actually changes between reads. Hence, this commit
restricts the warning to the latter situation.

Sebastien Bourdeauducq 9397fa7f5a hmc7043: unstick SYSREF FSM (#1055) 
Troubleshooting by David.

Additionally, register 7D is broken.
Checking phase init state has to be done through another means.

David Nadlinger 4359a43732 compiler: Indirection status of TTuple depends on elements 
For instance, TTuple(TList(TInt32())) has indirections, while
TTuple(TInt32()) does not.

This fixes memory corruption with RPCs that return tuples of lists.

Sebastien Bourdeauducq 729ce58f98 sayma: use GTP_CLK1 to clock DRTIO satellite transceiver 
This is required to get constant skew between the DRTIO transceiver clock
(which then generates the RTIO clock) and the siphaser reference clock.

Both the Si5324 and the RTM clock tree have non-deterministic in-to-out skew
at 150MHz due to dividers.

Sebastien Bourdeauducq a65721d649 sayma: put RTM clock tree into the siphaser loop 
* Fixes one bug where siphaser was one Si5324 output and the rest of the
system was clocked by the other. With the Si5324 settings we have, skew
between the outputs is not controlled.
* Puts the coaxial cable between AMC and RTM into the siphaser loop.

apatura-iris 5e5cdf0e67 Update installing.rst 
The file 99-openocd.rules as downloaded from githubusercontent.com seems to be outdated and does now work on Ubuntu 16.04. The version that ships with OpenOCD has an additional ``TAG+="uaccess"`` in the rules file and works fine. Thus I suggest to use the file that is bundled with OpenOCD.
