Add startOfDay() and endOfDay() methods to QDate
These methods give the first and last QDateTime values in the given
day, for a given time-zone or time-spec. These are usually the
relevant midnight, or the millisecond before, except when time-zone
transitions (typically DST changes) skip it, when care is needed to
select the right moment. Adapted some code to make use of the new
API, eliminating some old cruft from qdatetimeparser_p.h in the
process.
[ChangeLog][QtCore][QDate] Added startOfDay() and endOfDay() methods
to provide a QDateTime at the start and end of a given date, taking
account of any time skipped by transitions, e.g. a DST spring-forward,
which can lead to a day starting at 01:00 or ending just before 23:00.
