parameter-framework: initial commit

BZ: 6081

Parameter-framework is still-under-development, Intel proprietary,
multi-platform (standard C++, for now only linux, no dependency on
Android) software that allows system-wide parameter management. It
relies on a number of configurations files, from which it knows how
/ when to hand out settings towards the hardware (subsystems) at
runtime.
3 kinds of configuration files are used:
- Structure description files indicating the actual parameter
structure, types, min/max values, data representation.
- Configurable domain description file containing the actual
distribution of parameters over different domains, that is, different
set of configurations, each of which being dynamically activated
based on selection criteria rules that are themselves configurable.
Configurable domains file contain the tuned settings along the tuning
process, that is during the period where the system is being tuned.
- Binary settings file used to store the settings when the tuning
process is complete.

Changing any of those files causes no recompilation of the framework.
This project is based on a open plugin architecture allowing any kind
of subsystems to be handled, whatever their respective Endianness.
It fully relies on the platform SW to provide it with with the
kowledge of exisitng selection criteria (selected device, current
mode), as well as change events that occuring on them, thus
triggering the application of corresponding configuration settings
wherever appropriate.
It supports handling mutliple parameter classes (Audio, Energy
management) through TCP/IP interface.
For now tuning commands can be sent to parameter-framework instances
through a command-line utility, via adb over USB or via ethernet/WIFI.
