A previous change removed the limit of 64 cores by
moving away from 64-bit masks to char arrays. However
this left a buffer overrun issue, where the max channels
was defined as 64, and max cores was defined as 256. These
should all be consistently set to RTE_MAX_LCORE.
The #defines being removed are CHANNEL_CMDS_MAX_CPUS,
CHANNEL_CMDS_MAX_CHANNELS, POWER_MGR_MAX_CPUS, and
CHANNEL_CMDS_MAX_VM_CHANNELS, and are being replaced
with RTE_MAX_LCORE for consistency and simplicity.

This patch does a couple of things:
* Adds a new message type for removing policies (PKT_POLICY_REMOVE)
Used when we want to remove a previously created policy.
* Adds a core_type bool to the channel packet struct to specify whether
the type of core we want to control is virtual or physical.

Add the capability for the vm_power_manager to receive
a policy of type BRANCH_RATIO. This will add any vcpus
in the policy to the oob monitoring thread.

Macro CHANNEL_CMDS_MAX_CPUS stand for the maximum number of cores
controlled by virtual channels. This macro only be used in the example,
so remove it from library to example header file.

The CHANNEL_CMDS_MAX_VM_CHANNELS is duplicated in the channel_commands
header file. This commit removes that duplication.
