Removed Files:
        src/sys/compat/linux/common: linux_futex.c

Log Message:
Always clear FUTEX_PRIVATE_FLAG for Linux processes.  NetBSD-native futexes
exist in different namespace depending on FUTEX_PRIVATE_FLAG.  This appears
not to be the case in Linux, and some futex users will mix private and non-
private ops on the same futex object.  Provide a convenience wrapper that
puts this logic in one place witn a comment explaining why.

While here, move the Linux futex wrapper out of its own file and plop
it in linux_misc.c, which is where it lives in the linux32 module.
