Subject: [PATCH 05/41] uapi: mqueue.h: add missing linux/types.h include

Commit 63159f5dcccb ("uapi: Use __kernel_long_t in struct mq_attr")

changed the types from long to __kernel_long_t, but didn't add a

linux/types.h include.  Code that tries to include this header directly

breaks:

  /usr/include/linux/mqueue.h:26:2: error: unknown type name '__kernel_long_t'

  __kernel_long_t mq_flags; /* message queue flags   */

This also upsets configure tests for this header:

  checking linux/mqueue.h usability... no

  checking linux/mqueue.h presence... yes

  configure: WARNING: linux/mqueue.h: present but cannot be compiled

  configure: WARNING: linux/mqueue.h:     check for missing prerequisite headers?

  configure: WARNING: linux/mqueue.h: see the Autoconf documentation

  configure: WARNING: linux/mqueue.h:     section "Present But Cannot Be Compiled"

  configure: WARNING: linux/mqueue.h: proceeding with the compiler's result

  checking for linux/mqueue.h... no
