#1 fix known bugs

[Anonymous]

adding missing include string.h
and use standard integer types to avoid accidental 8 byte value
when 4 was intended (32bit vs 64bit long)

The "#include <string.h>" is needed because of the use of mem*() functions, but in ciso.c, not ciso.h.
IMHO all the structure members should use uint*_t types. Anyway, probably there are still endianness problems?
