Use log block for logging DT HW position switches.
Remove hard coded logging from safety block.
Leave the rest of the block intact for now.

It can now be used to make a dump from a trace stream on stdin.
Nice for taking a quick look at traces which were dumped to disk first.

Remove now unneeded nsec base time.
Command handling in the sample now uses trigger time.
Trace handling still has to be done, then all nsec timers can be removed
from the sample.

Sample counter removed from time interface. Only ec.c used it and it did not
add anything useful.
While sample is running trigger is now responsible for timestamps and
translation to wall clock. (allows external clock/trigger sources).
Log functions now log sub-second timestamps.

Default is set to true, if set to false console_httpd will directly connect
to the controller instead of the proxies.

Add test for quadrature decoder and optimize it a bit.

Optimize oneshot block a bit.

Add test blocks for sint32 inputs and outputs.
Also add tests for them to test.ctrl

(localhost resolves to ipv6 and ipv4 on video...)
Modify trace file dump to only 100k now the trace is more efficient.

  command line option '--history [seconds]'. The default is still 60
  seconds.
o Add a command line option '--interval [seconds]' to set the sample
  interval. The default sample interval without the options remains 0.2
  seconds as before.
o Add '--host [IP address or hostname]' command line option to view traces
  on a remote machine.
o Add '--port [remote port number]' command line option to specify the port
  number of the trace server to connect to.
o Add usage() function to inform user of possible optins.
o Keep track of the lowest and highest values in a plot and adjust the y
  range to be just over min and max so that all samples will fit within the
  plot, without the highest and lowest values dissapearing under the borders
  of the plot.

Optimize oneshot block and bridge_pwm block:
	-minimize amount of branches by removing sequence points.
	-Use local variables for structure fields to minimize dereferences.

compatibility code from controller_block.
Not having a create struct will now lead to failure to load the ctrl file.

Handy for testing, or scripts.

Add a little bit of logging.

When its 'reset' input is active, the output will always be off (=false).
When the 'set' input is active, the output will be turned on.
Once the 'set' input becomes inactive, the output will remain on for 'period'
seconds and then turn off.
A parameter called 'force' allows the block to be forced into the 'set' or
'reset' states.

Trace server capacity is now based on actuall number of outputs,
not on some magic number.
Add name and unit option to command_bool and command_float.
Modify tests to test this.

A lot simpler than the 1d and 3d setpoint generator and perfect for
temperature settings ;)
Add test for command_float block.

With this, we can create e.g. an oscillator module that only has an output,
but no inputs.

The 'filename' parameter wasn't initialized here, so when extra->filename is
used to generate e.g. log messages, garbage entered the log.

allows us to e.g. comment out all parameter lines in a parameter block.
(Commenting out all parameters would fail before.)

Also add test for different linking variants (late, immediate, not-chained).
All expected/assumed behaviour should get explicit tests.
Same for blocks. Block behaviour must be testable without the real application.
(or real hardware, which is the bigger problem)

Use one version everywhere, and make sure that one version is complete.
This version also uses a switch with the actuall enum types, which is safer.

We do this by checking the final state of all links after loading the top-most
controller file. The new code will allow an included file to create links to
blocks that will only exist later on during the load process, and it will
successfully error out when links are defined for non-existing block.

Furthermore, controller_block_link() will now bail out immediately when it
hits an unrecoverable linker error. With this change, the error mesaage of the
linker step that failed will remain at the end of the output instead of being
flushed off the screen by e.g. 100+ 'Linked x to y (chained)' lines.

This caused all my .ctrl files with typos or non-existing block names in their
'links { }' section to 'just run' instead of failing with an error.
We will now halt with an error like :

 DEBUG: Input block 'digg_out2' does not (yet) exist, will try to link later
 ERROR: Failed to link controller!
 ERROR: Could not load controller file

Untill now, connecting e.g. a 'bool' output to a 'float' input would give:

 ERROR: Input terminal x.y not found

.. although both the input and the output existed.
With this commit, the error will read :

 ERROR: Type mismatch. Can't connect output terminal a.b (of type 'bool') to
 input terminal x.y (of type 'float')
