unit-test: Add ovstest

Changing one of the files in the Open vSwitch ``lib'' directory
causes 43 binaries to be relinked, which takes a lot of time even with
parallel ``make''.  31 of those binaries are in the ``tests''
directory.  ovs-test attemps to combine most of those binaries into a
single test program that just takes a subcommand name as its first
command-line argument.

The following patch makes use of this infrastructure.

ofproto-dpif: Fix races in MPLS tests

Depending on how output buffers are flushed, there might
be still races.  But this at least makes the race windows smaller.

ofproto.at: Fix races in rule eviciton tests

Bump timeout differences, because timeouts different by 1s might end up
to have the same position in the heap as rule_eviction_priority() uses
1024ms as a unit.

Also, use time/stop to avoid relying on how long an add-flow would take.

These tests were introduced by commit 6d56c1f1.
("ofproto: Update rule's priority in eviction group.")

vtep: Add IP address configuration for bfd.

The OVS implementation of BFD allows configuration of the source and
destination IP addresses of BFD packets. This patch adds the same
configuration option to the VTEP schema.

datapath/flow: Fix ovs_flow_stats_get/clear RCU dereference.

For ovs_flow_stats_get() using ovsl_dereference() was wrong, since
flow dumps call this with RCU read lock.

ovs_flow_stats_clear() is always called with ovs_mutex, so can use
ovsl_dereference().

Also, make the ovs_flow_stats_get() 'flow' argument const to make
later patches cleaner.

datapath: Reduce locking requirements.

Reduce and clarify locking requirements for ovs_flow_cmd_alloc_info(),
ovs_flow_cmd_fill_info() and ovs_flow_cmd_build_info().

A datapath pointer is available only when holding a lock.  Change
ovs_flow_cmd_fill_info() and ovs_flow_cmd_build_info() to take a
dp_ifindex directly, rather than a datapath pointer that is then
(only) used to get the dp_ifindex.  This is useful, since the
dp_ifindex is available even when the datapath pointer is not, both
before and after taking a lock, which makes further critical section
reduction possible.

Make ovs_flow_cmd_alloc_info() take an 'acts' argument instead a
'flow' pointer.  This allows some future patches to do the allocation
before acquiring the flow pointer.

The locking requirements after this patch are:

ovs_flow_cmd_alloc_info(): May be called without locking, must not be
  called while holding the RCU read lock (due to memory allocation).
  If 'acts' belong to a flow in the flow table, however, then the
  caller must hold ovs_mutex.

ovs_flow_cmd_fill_info(): Either ovs_mutex or RCU read lock must be held.

ovs_flow_cmd_build_info(): This calls both of the above, so the caller
  must hold ovs_mutex.

datapath: Minimize ovs_flow_cmd_del critical section.

ovs_flow_cmd_del() now allocates reply (if needed) after the flow has
already been removed from the flow table.  If the reply allocation
fails, a netlink error is signaled with netlink_set_err(), as is
already done in ovs_flow_cmd_new_or_set() in the similar situation.
