net: core: Support UID-based routing.

This contains the following commits:

1. 0149763 net: core: Add a UID range to fib rules.
2. 1650474 net: core: Use the socket UID in routing lookups.
3. 0b16771 net: ipv4: Add the UID to the route cache.
4. ee058f1 net: core: Add a RTA_UID attribute to routes.
    This is so that userspace can do per-UID route lookups.

Enable setting security contexts on rootfs inodes.

rootfs (ramfs) can support setting of security contexts
by userspace due to the vfs fallback behavior of calling
the security module to set the in-core inode state
for security.* attributes when the filesystem does not
provide an xattr handler.  No xattr handler required
as the inodes are pinned in memory and have no backing
store.

This is useful in allowing early userspace to label individual
files within a rootfs while still providing a policy-defined
default via genfs.

uio: provide vm access to UIO_MEM_PHYS maps

This makes it possible to let gdb access mappings of the process that is
being debugged.

uio_mmap_logical was moved and uio_vm_ops renamed to group related code
and differentiate to new stuff.

Fix a few incorrectly checked [io_]remap_pfn_range() calls

Nico Golde reports a few straggling uses of [io_]remap_pfn_range() that
really should use the vm_iomap_memory() helper.  This trivially converts
two of them to the helper, and comments about why the third one really
needs to continue to use remap_pfn_range(), and adds the missing size
check.
