fa057b15bd V_irtualize flowtable state.
This change should make options VIMAGE kernel builds usable again,
to some extent at least.

Note that the size of struct vnet_inet has changed, though in
accordance with one-bump-per-day policy we didn't update the
__FreeBSD_version number, given that it has already been touched
by r194640 a few hours ago.

736801ace4 Garbage collect an extern for a non-existent variable.
While here let the comment end in a '.' and mark the #endif of _KERNEL.

53be8fca00 Move the kernel option FLOWTABLE chacking from the header file to the
actual implementation.
Remove the accessor functions for the compiled out case, just returning
"unavail" values. Remove the kernel conditional from the header file as
it is no longer needed, only leaving the externs.
Hide the improperly virtualized SYSCTL/TUNABLE for the flowtable size
under the kernel option as well.

8d8bc0182e After r193232 rt_tables in vnet.h are no longer indirectly dependent on
the ROUTETABLES kernel option thus there is no need to include opt_route.h
anymore in all consumers of vnet.h and no longer depend on it for module
builds.

Remove the hidden include in flowtable.h as well and leave the two
explicit #includes in ip_input.c and ip_output.c.

34b07340ff - Import infrastructure for caching flows as a means of accelerating L3 and L2 lookups
as well as providing stateful load balancing when used with RADIX_MPATH.
- Currently compiled in to i386 and amd64 but disabled by default, it can be enabled at
  runtime with 'sysctl net.inet.flowtable.enable=1'.

- Embedded users can remove it entirely from the kernel by adding 'nooption FLOWTABLE' to
  their kernel config files.

- A minimal hookup will be added to ip_output in a subsequent commit. I would like to see
  more review before bringing in changes that require more churn.
