linker section tricks. Fallback is to manually call the init function of
each labcomm module.

[GNU] ld tricks (instead we rely on cpp tricks and some heuristics
for memory allocation) so we probably should rewrite labcomm compiler
to generate cleaner code for this use-case.

Fixed python encode_byte to be unsigned.

reception of remote declaration. Corrected twoway/decimating.c
to take advantage of this.

Fixed recursion bug in scheduler.

New scheduler abstraction in place.

Coreccted LabComm.py

labcomm_internal_encode, this triggered lots of changes to handling of 
stacked writer allocation. Twoway example is not finished yet.

Start of adding GPLv3 licensensing.

Labcomm cleanup (still more to do)

Added dynamic macros and code for dynamic arrays indexed by signature
index.
