Patch to eliminate bcopy from the java directory

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

This patch eliminates bcopy from the java directory.  I'd appreciate
it if the reviewer would double check whether the memcpy calls should
in fact be memmove instead.

Ok to install?

	* constants.c (PUTN): Use memcpy, not bcopy.

	* lex.c (java_read_char): Use memmove, not bcopy.

	* parse.y (java_parser_context_resume): Use memcpy, not bcopy.
