update license to GPLv2 and GPLv3

[radiotest] - minor debugging tweaks

[pico_frame] - Also added deepcopy of 'info'-field in pico_frame_deepcopy. Should fix #435

[pico_frame] - cast to size_t

[pico_frame] - Moved to ISO ptrdiff_t for pointer arithmetic, should fix #423

[pico_frame] - Updated to native pointer arithmetic type. This fixes a OOB derefence on my 64-bit Debian machine. This regards #405

[pico_frame] - added possibility to grow the headroom provided

[pico_frame] - added possibility to grow the headroom provided

Improved C89 compatability (e.g. Watcom compiler)

Reviewed coding style, preparing for release

Update datalink hdr in frame grow and deepcopy

Improved "pico_frame_grow"

Update headers for new buffer

Added "pico_frame_grow"

Made style with uncrustify

new checksum function is final

Bugfix: in commit 1e3a87cacfca08, wrong frame->len is set, so usage

count may be overwritten later on.

Possible cause for hang in autotests.

add cast b/c sizeof() returns 64bit value on 64bit machine

Fixed #223: Avoid double allocation for frame buffer and usage counter

Updated Copyright information.

Coding style enforced.

Remove wrong and unnecessary check

!zerocopy should be used instead of !ext_buffer. But p->buffer is set to
NULL when zerocopy != 0, so we can just check for p->buffer.

Added function pico_stack_recv_zerocopy_ext_buffer_notify()

Fix for commit: Added young checksum (faster than old one) selectable by Makefile

Previous commit wich does not contains the modification of file pico_frame.c

Added young checksum (faster than old one) selectable by Makefile

Checksum code has been refactored to isolate common component

Enforced coding style via uncrustify

Changing flags types to machine-integer to optimize storing on 8/16bit archs

Implement pico_stack_recv_zerocopy_ext_buffer

Fixed sign conversions in crc calculation

Improved performance of CRC calculation

Runned make style and fixed some warnings

Added pico_stack_recv_zerocopy() [UNTESTED]

'make style' adjusted formatting

Fixed possible NULL dereference in pico_frame_discard()

Removed some dead code

* changed pico_free into PICO_FREE
* changed pico_zalloc into PICO_ZALLOC

Added uncrustify. Enforced some coding rules. Added "make style" target.

Issue #17. Fixed warnings (part three)

Issue #17. Fixed warnings (part two)

Issue #17. Fixed warnings (part one)

Added some compiler flags (commented out at the moment) that are needed for a good score for TIOBE TICS framework

Fixed bug in checksum calculations. A second carry was never taken into account.

Fixed checksum bug when using dualbuffer checksum routine.
On 16 bit systems this will fix a lot. Refer to commit 5514fbf

Implemented Frame deepcopy. Fixed TCP QUAD match.

Fixed "duple" management

Bugfix: make remote information persistent on UDP sendto

Task #442 Integrated the new rb library + unit tests for it + a few bugfixes

Reworked static objects in the modules, to allow unit tests to include .c files

Changed LICENSE to GPL2. Removed the do-not-distribute clause from the source headers

Task: #107 Description: Checksum is not correct on a 16 bit platform Changes: Bit shifting to the left is marked by the compiler as a warning when shifting >= the variable size. If ignore, an arythmetic shift is added between the instructions, causing the result to go wrong when the sign bit is hit (even though not using signed variables). This problem is fixed by first moving the variable into a suitable large variable. Then you can perform the shift. Tested: The results of a linux-32bit-system were compared with the ones on a pic24F (16 bit) for multiple inputs. UDP and ping replies are fully functional now

Added copyright notice on top of each file.

(closes issue #100)

Fixed bug in receiver.

Fixed all memory leaks in the stack!

yay! TCP send works now. A few glitches on consecutive writes?

Added more tcp output functions. Still cannot send

Fixed makefile, initials for tcp connection. Accepted socket not added?

Fixed TCP checksum (yay!)

Fixed bug in queues

Fixed problem with arp requests...

Implemented icmp echo reply. 2 bugs:

- Icmp crc is not correct.
- Sometimes segfault: investigate.

Reorganized directory structure.
