Don't intialize bool or uint32_t with float value.

My .ctrl file is so much cleaner this way :)

Before, a value of '1.0' had to be created like this :

	blocks(..) {
		{ "value", "one" }
	}
	params {
		{ "one", "value", 1.0 }
	}

Now you can simply instantiate the same block with :

	blocks(..) {
		{ "value", "one", 1.0 }
	}

I've finally found a good use for fully specified multiple choice argument
lists :)

Add return value to controller_block_add() and add a check to the
blocks for its value.

Add return value to controller_block_add() and add a check to the

Its output will rise when (positive > negative + window/2) and fall when
(positive < negative - window/2).

The block will output 'true' when input positive >= input negative.

This way we can use one function to set a number of params. All blocks
(including the il2c generator) have been updated with the extra argument.

Add module code in controller_module
Introduce new test for module
Use module in azimuth and elevation simulators
Remove dedicated simulator blocks

one recipe to be specified per target. When multiple recipes are defined for
the same target, only the last one will be executed.
This change makes executing the 'all' target in the controller/ or
controller/block/ directory actually only build files inside these directories
instead of starting a full build at the top level directory.

Making 'clean' in either of these directories still cleans the entire build
starting from the top level directory. I think this eventually deserves a
second commit. I would like to be able to only 'clean' a subdirectory.

Add realloc function to controller_mem
Move reallocs in blocks to new controller_mem functions
Add test case for block_state_machine.

Add controller_mem memory allocation functions.
All periodic data will be allocated in a continuous piece of memory hoping
for optimall cache behaviour with regards to associativity.
(TODO: really allocate continuous memory at the other side of the MMU)

Fix some remaining parameter arguments
Add argument checking to il2c generated blocks.

Als add parameter description and check to parameter lists.

(small parser errors due to missing punctuation)

Blocks can now check the number of arguments before parsing them.

Move some more time related stuff to controller_time
Add code to handle skipped samples.

The frequency keyword has been removed.
The blocks keyword now needs two arguments: frequency (Hz) and delay (seconds)

Also allocate as many interms and outterms with helper functions as possible.

Now it is possible to add parameters multiple times and we no longer depend
on the location of the parameter in the list.

Add the 'pand' block.

Don't try to link against 'libdl' on FreeBSD. dlopen() and friends are in libc
there.

Use immediate trigger in test.ctrl files.
Fix some bugs

Cleanup libs
Add lib dependancies for console_httpd.
Add inf as double constant.

Lots of test updates

Fix some setpoint generator quirks

New 1d setpoint generator for simple control
Added test blocks
Added tests for some blocks
Removed broken iir_test

Fix block dependencies

Various small fixes
Add command protocol to websocket
Add cross compiling with 'TARGET='
Fix some issues with ARM
