power: fix build with libvirt

Following moving rte_power_guest* API from the power library to the
kvm_vm driver, the symbols are not exposed anymore, since the library
hosting them is the kvm_vm driver binary.

Finish this cleanup by hosting the rte_power_guest_channel.h header in
the driver, then version the symbols and add corresponding build
dependencies in the vm_power_manager example.

With fix, attempting to use a VERY lonng vm name results in a nicely

Setting VM Name to [sdfdsfsfsdffdsdsasdsadasdakjshd]

Using strlcpy rather than rte_strlcpy, as the rte_ version is only a
fallback.

As well as the fix in main.c, this patch also changes an occurrence of
rte_strlcpy in channel_manager.c and channel_monitor.c to strlcpy.

examples/vm_power: add options to guest app

Add new command line arguments to the guest app to make
testing and validation of the policy usage easier.
These arguments are mainly around setting up the power
management policy that is sent from the guest vm to
to the vm_power_manager in the host

New command line parameters:
-n or --vm-name
sets the name of the vm to be used by the host OS.
-b or --busy-hours
sets the list of hours that are predicted to be busy
-q or --quiet-hours
sets the list of hours that are predicted to be quiet
-l or --vcpu-list
sets the list of vcpus to monitor
-p or --port-list
sets the list of posts to monitor when using a
workload policy.
-o or --policy
sets the default policy type
TIME
WORKLOAD
TRAFFIC
BRANCH_RATIO

The format of the hours or list paramers is a comma-separated
list of integers, which can take the form of
a. x e.g. --vcpu-list=1
b. x,y e.g. --quiet-hours=3,4
c. x-y e.g. --busy-hours=9-12
d. combination of above (e.g. --busy-hours=4,5-7,9)

examples/vm_power: cli in guest

Provides a small sample application(guest_vm_power_mgr) to run on a VM.
The application is run by providing a core mask(-c) and number of memory
channels(-n). The core mask corresponds to the number of lcore channels to
attempt to open. A maximum of 64 channels per VM is allowed. The channels must
be monitored by the host.
After successful initialisation a CPU frequency command can be sent to the host
using:
set_cpu_freq <lcore_num> <up|down|min|max>.
