TinyCBOR release 0.4.1
This is a bug-fix release. There is no new functionality on top of
v0.4.
Bugs fixed:
- #54 Failure to build with newest cJSON upstream
- Stack corruption when memcpy doesn't use the same calling convention
- Warnings with GCC -pedantic in cbor.h
- a number of buildsystem bugs

Fix stack corruption due to calling convention mismatch
Standard library implementations may specify calling convention for memcpy
explicitly. However, the cbor* APIs don't do that. If you compile the lib
with default calling convention that doesn't match the calling convention o
memcpy(), the iterate_string_chunks() will not setup the stack for memcpy()
call correctly resulting in a stack corruption. The compiler doesn't catch
this issue because of the cast that is being applied when passing memcpy()
to the iterate_string_chunks().
The fix is to wrap memcpy() in a function that conforms to the declaration o
the IterateFunction which does two things, removes the need for a cast and
uncouples memcpy() calling convention from the rest of the cbor* APIs.
