The bswap16, bswap32 and bswap64 functions are already present on NetBSD
and cannot be redefined in include/vlc_common.h as this causes fatal build
errors.

Rename these functions to vlc_bswap16, vlc_bswap32 and vlc_bswap64 and
keep them as they are without fallback to the NetBSD's libc one. These
functions are already small enough and we can bear with them as duplicates
on the gain of no extra ifdefs in the vlc_common.h public header.
