tests: fix failure when $PKIDIR contains uuid-like string

this fixes a test failure with my working directory:
    /disks/ea6a5743-ad5f-11e2-9410-08606e7f74e7/git/openvswitch

stop filtering uuid as it's unnecessary for this specific test case.

vxlan: Optimize vxlan rcv

vxlan-udp-recv function lookup vxlan_sock struct on every packet
recv by using udp-port number. we can use sk->sk_user_data to
store vxlan_sock and avoid lookup.

This commit also allows us to get rid of socket hash table.

meta-flow: Add mf_mask_field_and_prereqs().

Sets mask bits for the given field and its prerequisite fields.
Needed for unwildcarding the proper bits from datapath masks.
Removed old prototype for mf_force_prereqs().

Set datapath mask bits when setting a flow field.

Since at the datapath interface we do not have set actions for
individual fields, but larger sets of fields for a given protocol
layer, the set action will in practice only ever apply to exactly
matched flows for the given protocol layer.  For example, if the
reg_load changes the IP TTL, the corresponding datapath action will
rewrite also the IP addresses and TOS byte.  Since these other field
values may not be explicitly set, they depend on the incoming flow field
values, and are hence all of them are set in the wildcards masks, when
the action is committed to the datapath.  For the rare case, where the
reg_load action does not actually change the value, and no other flow
field values are set (or loaded), the datapath action is skipped, and
no mask bits are set.  Such a datapath flow should, however, be
dependent on the specific field value, so the corresponding wildcard
mask bits must be set, lest the datapath flow be applied to packets
containing some other value in the field and the field value remain
unchanged regardless of the incoming value.

connmgr: Always send full packet in packet_in when not buffering.

According to the specs, if a packet is not buffered for some reasons,
we should send the entire packet, regardless of max_len.
