Improve safe alignment buffer handling macros
Make the counter optional so that alignment safe macros can be used also where there is no counter to update. Change arguments names so that they are not deceiving (ptr normlly identify a pointer) Turn the memcpy substitute into an inline function so that passing a pointer to rp and checking for it doesn't make the compiler spit lots of warnings.
