ipsec: fix udp-encap in transport mode

Now UDP enacapsulation doesn't work in transport mode with crypto
algorithms that have iv_sz=8 like AES GCM or 3DES CBC. That happens
because the inserted UDP header overlaps with the old IP header and
gets filled before the information from the old IP header can be
copied to a new IP header. The result is a broken packet:

00:03:39:620863: esp4-encrypt-tun
  esp: sa-index 3 spi 3464048590 (0xce792fce) seq 31 sa-seq-hi 0

dpdk: false link down issue with ixgbe NIC

This issue is observed with X520-2 NICs on FD.io lab Taishan server.
After VPP booting up and bringing up  the interfaces with command "set
interface state <interface> up", it still shows link down status from
the command "show hardware-interfaces". However, the hardware link
status is actually up. dpdk_process() cannot get the hardware link
status correctly via rte_eth_link_get_nowait().

In ixgbe_dev_link_update_share(), if the media type is fiber and the
link is down, a flag (IXGBE_FLAG_NEED_LINK_CONFIG) is set. A callback to
ixgbe_dev_setup_link_alarm_handler() is scheduled trying to set up the
link and clear the flag afterwards.

If the device is started or stopped before the flag is cleared, the
scheduled callback is canceled. This causes the flag to remain set and
subsequent calls to ixgbe_dev_link_update_share() return without trying
to retrieve the link state because the flag is set.

When the callback is canceled by either interface start or stop
operation, in ixgbe_dev_cancel_link_thread(), after cancelling the
callback/thread, unset the flag on the device to avoid this condition.

vlib: leave SIGPROF signal with its default handler

When profiling VPP with MAP (a software profile suite on Arm CPUs, see details in
https://www.arm.com/products/development-tools/server-and-hpc/forge/map) on Arm
servers, VPP will receive SIGPROF signal because MAP uses SIGPROF signal to drive
its sampler to do profiling on VPP. However, the default action of SIGPROF signal
handler in VPP such as unix_signal_handler() is process termination. To profile
VPP with MAP, the SIGPROF handler should be left as default, and MAP sampler will
overwrite it with its own implementation.
