The linked version was not usable, and there were

still work to do.

The same will be done on the RFC wrappers

Due to the wrking threads we can not really move
the RAW of RFC decoders.

We *can* move the wrappers, and *_void however.

encode() was still expecting the symbol in
host endianness. the iterator was calling it
with the host endianness, too, so we did not notice.

The funny thing? The stable version was patched
correctly, and does not have this problem...

block_size() optimistically reported the block size
as extracted from the partitioning. The problem
is that the last block is not always full, so the
last block had the wrong size.

Fixes #24



Sometimes it makes sense to have incomplete data.
This way we both de-interleave the incomplete data
and we give a std::vector<bool> of which bytes were
transmitted correctly and which were zeroed out.

Accessible through the end_of_input() calls, as it is the
only call that makes sense for this, since we need to
also ignore any other repair symbol.

The de_interleaver was still following the

real number of symbols in the block.

Loop from 'i' to 'M' instead of 'i' to 'L' during Gaussian elimination in the
second phase.

Signed-off-by: Anders Martinsson <anders.martinsson@intinor.se>

This probably comes from a ill-fated idea to optimize and stop after the
triangular matrix is parsed, but that prevented us from parsing
other repair symbols. Which is really wrong.

We were doing really bad stuff.
* we were not using the correct block size, but instead
  creating something completely out-of standard
  This surely means that we were not compatible with
  OpenRQ (Ticket #20), and possibly a reason for which
  decoding fails too ofter (Ticket #21).
* We used the wrong ESI number, which should skip
  the padding numbers (#23, #20

)
* we did not expose the real block size to the user
  of the RFC namespace (RFC iterators)

Signed-off-by: Luca Fulchir <luker@fenrirproject.org>

We only report the number of symbols used in a block,
but you might want to know the size of the matrix we
use internally.

The OTI fields and the symbol id are all in big endian.
We used the host endianness instead. fix that.

update docs: a variable was renamed to keep the
C and C++ versions in sync

Signed-off-by: Luca Fulchir <luker@fenrirproject.org>

...which brings some API breakage :(

notable things:

* C and C++ names for structs and variables are now in sync
* common.hpp is much easier to read
* added "trcked by" "tracks ..." to know that some things
  are to be kept in synch between C and C++
* "RaptorQ_Dec_Result" name was too similar to
  "RaptorQ_Decoder_Result". The C++ version calls it
  "Decoder_wait_res", let's go with that, at least it
  is more different and actually more to the point.

Signed-off-by: Luca Fulchir <luker@fenrirproject.org>

Just using wait() on the future does not give the
same semantic meaning as decode_once, which can sometimes
be needed.

Also, the C++ API exposes that, so the C API should really
track it.
