5e1f62fb1a power: clean KVM files
rename private header file rte_power_kvm_vm.c
to power_kvm_vm.c. This prevents the private
functions from leaking into the documentation.
Change any private functions from
rte_<function_name> to just <function_name>.
Reserve the rte_ for public functions

969e82ad81 power: changed unsigned to unsigned int
Since this patch-set attempts to clean up the power library,
and there are many instances of "unsigned" caught by checkpatch,
it was decided to clean these up first rather than have them included
in the later patches in the patch set. And would also minimise this
type of error being caught by checkpatch in the future

445c6528b5 power: common interface for guest and host
Moved the current librte_power implementation to rte_power_acpi_cpufreq, with
renaming of functions only.
Added rte_power_kvm_vm implementation to support Power Management from a VM.

librte_power now hides the implementation based on the environment used.
A new call rte_power_set_env() can explicidly set the environment, if not
called then auto-detection takes place.

rte_power_kvm_vm is subset of the librte_power APIs, the following is supported:
 rte_power_init(unsigned lcore_id)
 rte_power_exit(unsigned lcore_id)
 rte_power_freq_up(unsigned lcore_id)
 rte_power_freq_down(unsigned lcore_id)
 rte_power_freq_min(unsigned lcore_id)
 rte_power_freq_max(unsigned lcore_id)

The other unsupported APIs return -ENOTSUP

6f41fe75e2 eal: deprecate rte_snprintf
The function rte_snprintf serves no useful purpose. It is the
same as snprintf() for all valid inputs. Deprecate it and
replace all uses in current code.

Leave the tests for the deprecated function in place.

3031749c2d remove trailing whitespaces
This commit removes trailing whitespace from lines in files. Almost all
files are affected, as the BSD license copyright header had trailing
whitespace on 4 lines in it [hence the number of files reporting 8 lines
changed in the diffstat].
