QBBSystemLocaleData emits qwarnings when it fails to open or read a pps object.
If the user code installs a message handler that will invoke QLocale API again
(i.e QDate, QDateTime, ...) which leads to a deadlock situation, since
the QBBSystemLocaleData global static object's ctor() is not yet done.
This patch logs the QBBSystemLocale's warnings to stderr and
skips the Qt message handler.

This code was duplicated in every qcollator_platform.cpp and identical everywhere,
except in _icu, which uses a QByteArray m_key and the implementation used
QByteArray::operator<, which is semantically and probably code-wise identical to
what the other implementations did (after inlining).
Inlining this function removes a potential maintenance problem and increases
speed without violating encapsulation.

This necessitates adding d==0 checks in QCollator. By documenting that
moved-from instances can only be assigned to or destroyed, we can
limit the functions in which to check for d==0 to the assignment
operator and the destructor.
Doing otherwise would destroy all advantages of move semantics by
introducing a heap allocation to re-populate other.d.
Add a test for this (QCollator didn't have any before).

Other static data such as QTextStream might be initialized before the
static C-locale, in which case QLocale would adopt c_private and bump
the ref-count to 2, only to see it reset back to 1 when the c_locale's
static initialization happened.
The result was that at application shutdown the ref-count would fall
down to 0, and we tried deleting the static data.
This issue was observed with clang in a debug build, where the c_private
is initialized at runtime.

At the Daylight Tme to Standard Time transition, the local time repeats
itself, i.e. 2am occurs twice. Qt's behavior when setting this using
the local time is ambiguous, as it depends on the system implementation
of mktime, which behaves differently on different platforms. Currently
this behavior remains undefined. When setting using an msecs or time_t
value however we can determine the correct instance to use and cache it
to ensure that any conversion back from local time to msecs is performed
consistantly on all platforms.
Note that caching this value will result in any calculations being wrong
should the system time zone change, or its rules change. This will be
fixed in Qt 5.3 when the system time zone change signal is implemented
and QDateTime switches to using QTimeZone instead of mktime to provide
consistnt behavior across platforms.
The QTimeZone spec does not require this fix as it already caches the
correct offset in setMSecsFromEpoch().
