[PATCH 1/3] bitops: Fix big endian compilation

[Rosen Penev <rosenp@gmail.com>]

Replaced bswap with _ variants. While it's a glibc extension, all of the
popular libc implementations (glibc, uClibc, musl, BIONIC) seem to support
it.

Added static inline to two functions to match little endian variants. This
fixes a linking error experienced when compiling.
