[DVDnav-discuss] [PATCH] [?] Don't check for memcpy() presence, assume it's available

[Diego 'Flameeyes' Pettenò]

I can't think of any case off the top of my head where memcpy()
function is not available, and bcopy has to be used instead, but the
md5.c source file (from dvdread) seems to be taken out of glibc, and it
checks for HAVE_MEMCPY before using it, otherwise uses bcopy.

With this patch (that I'm not sure if it's okay to apply as it changes
dvdread sources), memcpy check is skipped, and it's always used instead.

This also removes the implicit declarations warnings (that become errors
when compiled with xine).

Note that luckily the return value of memcpy() is never used in md5.c
so there's no risk that a broken pointer is dereferenced with the
implicit declarations.
