autofs: new package

Tested on i.MX6 using NFS mounts only. Not tested with DAS mounts as
of this commit.

[Thomas:
 - remove the "# rpcbind" comments on the thread and mmu dependencies,
   since we don't select rpcbind. The thread and mmu dependencies are
   still needed though, since autofs uses pthread_*() functions and
   fork().
 - Remove "Requires a toolchain with native RPC." in the Config.in
   help text and instead add a proper Config.in comment about the
   thread and RPC dependency.
 - Add patch to fix building with uClibc, taken from OpenEmbedded.]

+Subject: [PATCH] autofs-5.0.7: include linux/nfs.h directly in rpc_subs.h
+
+Fixes compile error with uclibc. Glibc's nfs/nfs.h contains
+nothing but "#include linux/nfs.h". rpc_subs.h already includes
+other linux/nfs*.h files directly.

+	  Autofs controls the operation of the automount daemons. The
+	  automount daemons automatically mount filesystems when they
+	  are used and unmount them after a period of inactivity based
+	  on a set of pre-configured maps defined by default in
+	  /etc/auto.master. The kernel automounter implements SunOS
+	  style automounter under Linux and requires a kernel version
+	  of at least 2.6.17 and the autofs4 kernel module.
