Support for compile time generated QStrings
use with QString string(QStringLiteral("foo")) or
QString string(qs("foo")).
qs(...) can in almost all places replace QLatin1String.
the Macro qs requires c++0x support or a compiler
where sizeof(wchar_t) == 2. In case these conditions
are not met, qs simply falls back to QLatin1String.
The commit also cleans up the QStringData structure
significantly, now using only 16 bytes for the header
on 32 bit systems.
The bitflags to store unicode directionality of the string and whether the string would require complex text processing to render are removed. They don't really belong here and the result can be calculated very fast in any case.
Added an internal QRefCount class the encapsulates the
reference counting semantics required where a negative refcount
is never changed. This is required to be able to put the string
data into a constant POD object.
