PFW: Enum parameter mapping

BZ: 22125

Enum parameter types are now fully parsed as any other types, which allow
Mapping attributes to be correctly interpreted.
Now inner structure of enum parameter types is based on automatically
created objects: ValuePair

Slight adaptation of to ICS environment in Android.mk files and
XmlComposer (time.h).

More explicit error statement issued in case of plugin load failure in
SystemClass.cpp.

Added a log for Alsa mixer elements accesses.
