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.

New scheduler abstraction in place.

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.

Changed reader/writer interface to simplify stacking (example will 
be forthcoming).

fd_reader/writer more robust: no dependency on 'int *fd' to be live
while the reader/writer is in use).

labcomm_encoder/labcomm_decoder into labcomm.c

labcomm_encoder_ioctl_)

continuation bit. C# is currently (intentionally) broken. 
Java and Python are untested.

labcomm_encode_type_index, labcomm_encoder_end

Added test of generated C encoders.

encoder indices (linker magic provided). 

Testcase for some of the encoding/decoding functions.
