Add vrouter version to kernel module

[Slobodan Blatnjak]

The kernel module for the vrouter is not properly versioned. So it cannot be inspected with lsmod.

Current behaviour:

# modinfo vrouter
filename: /lib/modules/3.13.0-92-generic/updates/dkms/vrouter.ko
version: 1.0
license: GPL
srcversion: 86FE61ACD774E38372BBA23
depends:
vermagic: 3.13.0-92-generic SMP mod_unload modversions
parm: vr_flow_entries:uint
parm: vr_oflow_entries:uint
parm: vr_bridge_entries:uint
parm: vr_bridge_oentries:uint
parm: vr_mpls_labels:uint
parm: vr_nexthops:uint
parm: vr_vrfs:uint
parm: vrouter_dbg:Set 1 for pkt dumping and 0 to disable, default value is 0 (int)

Desired behaviour:

# modinfo vrouter
filename: /lib/modules/3.13.0-92-generic/updates/dkms/vrouter.ko
version: 2.21.2-43
license: GPL
srcversion: 86FE61ACD774E38372BBA23
depends:
vermagic: 3.13.0-92-generic SMP mod_unload modversions
parm: vr_flow_entries:uint
parm: vr_oflow_entries:uint
parm: vr_bridge_entries:uint
parm: vr_bridge_oentries:uint
parm: vr_mpls_labels:uint
parm: vr_nexthops:uint
parm: vr_vrfs:uint
parm: vrouter_dbg:Set 1 for pkt dumping and 0 to disable, default value is 0 (int)

The version info is available in "vrouter --info" output.

[Slobodan Blatnjak (sblatnjak)]

Customer still think it would be good practice to have the modinfo show the correct version as well (low priority)

Add GetBuildVersion as a method in the env

vRouter needs build/version information as a string literal. Adding
GetBuildVersion to the environment as a method and using that in
the SConscript is probably the cleanest way of getting to the version
string.

Set the module version id to that of the release id

Get the build version from the environment and use that to set
the kernel module's version id. For DKMS, the version id is
passed as an argument to the gen_build_info script.
