SVN rev 191269 on 2009-04-19 13:48:42Z by dchagin
Remove support for FUTEX_REQUEUE operation.
Glibc does not use this operation since 2.3.3 version (Jun 2004),
as it is racy and replaced by FUTEX_CMP_REQUEUE operation.
Glibc versions prior to 2.3.3 fall back to FUTEX_WAKE when
FUTEX_REQUEUE returned EINVAL.
Any application directly using FUTEX_REQUEUE without return
value checking are definitely broken.
Limit quantity of messages per process about unsupported
operation.
