MFC r314651,r318439,r318440:
r314651:
sys/modules: normalize .CURDIR-relative paths to SRCTOP
This simplifies make output/logic
Tested with: `cd sys/modules; make ALL_MODULES=` on amd64
r318439:
Normalize .PATH on SRCTOP
This will help Jenkins dedupe 9 warnings between the static build and the module build of ipsec(4).
Missed in SRCTOP conversion in r314651.
MFC with: r314651
r318440:
Normalize SYSDIR on SRCTOP instead of .CURDIR
This is being done to simplify pathing for CFLAGS and source files.

Add vxlan interface
vxlan creates a virtual LAN by encapsulating the inner Ethernet frame in a UDP packet. This implementation is based on RFC7348.
Currently, the IPv6 support is not fully compliant with the specification: we should be able to receive UPDv6 packets with a zero checksum, but we need to support RFC6935 first. Patches for this should come soon.
Encapsulation protocols such as vxlan emphasize the need for the FreeBSD network stack to support batching, GRO, and GSO. Each frame has to make two trips through the network stack, and each frame will be at most MTU sized. Performance suffers accordingly.
Some latest generation NICs have begun to support vxlan HW offloads that we should also take advantage of. VIMAGE support should also be added soon.
