Fixes warnings like
blake2.h(140): warning C4804: '/': unsafe use of type 'bool' in operation
blake2.h(141): warning C4804: '/': unsafe use of type 'bool' in operation
This patch makes the BLAKE2 reference implementation compatible with C89
compilers and MSVC.
1) Use C comments (/* */) instead of C++ comments.
2) No declarations after statements. All variables are declared on the
top of a block.
3) Optional inline with BLAKE2_LOCAL_INLINE() macro.

While the param structs need to be packed, because they're compressed as
a byte stream, the state structs do not have this requirement. As such,
the compiler likely can emit more efficient code in certain
circumstances when it can apply the ordinary struct alignment rules.
