- update kv_kvp_daemon to 3.7-rc1 state [fate#31441]
  support KVP IP Injection, helper scripts go to /usr/lib/hyper-v/bin:
  hv_get_dhcp_info, hv_get_dns_info, hv_set_ifconfig
- remove usage of absolute paths in runlevel script

/*
* As we look at expanding the KVP functionality to include
* IP injection functionality, we need to maintain binary
* compatibility with older daemons.
*
* The KVP opcodes are defined by the host and it was unfortunate
* that I chose to treat the registration operation as part of the
* KVP operations defined by the host.
* Here is the level of compatibility
* (between the user level daemon and the kernel KVP driver) that we
* will implement:
*
* An older daemon will always be supported on a newer driver.
* A given user level daemon will require a minimal version of the
* kernel driver.
* If we cannot handle the version differences, we will fail gracefully
* (this can happen when we have a user level daemon that is more
* advanced than the KVP driver.
*
* We will use values used in this handshake for determining if we have
* workable user level daemon and the kernel driver. We begin by taking the
* registration opcode out of the KVP opcode namespace. We will however,
* maintain compatibility with the existing user-level daemon code.
