bswap: improve gluing

OpenBSD system compiler (gcc 4.2.1) has problems with concatenation
of macro arguments in macro functions:
  CC    aes.o
In file included from /src/qemu/include/qemu-common.h:126,
                 from /src/qemu/aes.c:30:
/src/qemu/include/qemu/bswap.h: In function 'leul_to_cpu':
/src/qemu/include/qemu/bswap.h:461: warning: implicit declaration of function 'bswapHOST_LONG_BITS'
/src/qemu/include/qemu/bswap.h:461: warning: nested extern declaration of 'bswapHOST_LONG_BITS'

Function leul_to_cpu() is only used in kvm-all.c, so the warnings
are not fatal on OpenBSD without -Werror.

Fix by applying glue(). Also add do {} while(0) wrapping and fix
semicolon use while at it.
