Use standard size_t type in the casts for length-parameter of memcpy, memmove

and bzero.  When the library was written (1989), none of those had been
standardized, and the source-code used "(int)" casts to help with K&R
compilers.  The cleanup done in the previous update used binary-compare
to validate, which does not work for these because the compiler is recording
the cast's effect.

This change reduces the number of gcc warnings from 163 to 128.
