While QArrayDataPointer offers generic detach() functionality, this is
only useful for operations that may modify data, but don't otherwise
affect the container itself, such as non-const iteration, front() and
back().
For other modifying operations, users of the API typically need to
decide whether a detach is needed based on QArrayData's requirements
(is data mutable? is it currently shared?) and its own (do we have
spare capacity for growth?).
Now that data may be shared, static or otherwise immutable (e.g.,
fromRawData) it no longer suffices to check the ref-count for
isShared().
This commit adds needsDetach() which, from the point-of-view of
QArrayData(Pointer), answers the question: 'Can contained data and
associated metadata be changed?'.
This fixes QArrayDataPointer::setSharable for static data (e.g.,
Q_ARRAY_LITERAL), previously it only catered to shared_null.
SimpleVector is also fixed since it wasn't checking Mutability and it
needs to because it supports fromRawData().

This enables a truncating resize() to be implemented. It is similar to
destroyAll(), but updates the size() as it goes, so it is safe to use
outside a container's destructor (and doesn't necessarily destroy all
elements).
The appendInitialize test was repurposed and now doubles as an
additional test for QArrayDataOps as well as exercising SimpleVector's
resize().

This follows QArrayData::detachFlags's lead. Given the (known) size for
a detached container, the function helps determine capacity, ensuring
the capacityReserved flag is respected.
This further helps aggregating behaviour on detach in QArrayData itself.
SimpleVector was previously using qMax(capacity(), newSize), but there's
no reason to pin the previous capacity value if reserve() wasn't
requested. It now uses detachCapacity().

Also say hello to QUrl's constructor and QUrl::toString being allowed
again.
QUrl operates now on UTF-16 encoded data, where a Unicode character
matches its UTF-8 percent-encoded form (as per RFC 3987). The data may
exist in different levels of encoding, but it is always in encoded
form (a percent is always "%25"). For that reason, the previously
dangerous methods are no longer dangerous.
The QUrl parser is much more lenient now. Instead of blindly following
the grammar from RFC 3986, we try to use common-sense. Hopefully, this
will also mean the code is faster. It also operates on QStrings and,
for the common case, will not perform any memory allocations it
doesn't keep (i.e., it allocates only for the data that is stored in
QUrlPrivate).
The Null/Empty behaviour that fragments and queries had in Qt4 are now
extended to the scheme, username, password and host parts. This means
QUrl can remember the difference between "http://@example.com" and
"http://example.com".

This class is meant to replace the QUrl functionality that handled
key-value pairs in the query part of an URL. We therefore split the
URL parsing code from the code dealing with the pairs: QUrl now only
needs to deal with one encoded string, without knowing what it is.
Since it doesn't know how to decode the query, QUrl also becomes
limited in what it can decode. Following the letter of the RFC,
queries will not encode "gen-delims" nor "sub-delims" nor the plus
sign (+), thus allowing the most common delimiters options to remain
unchanged.
QUrlQuery has some undefined behaviour when it comes to empty query
keys. It may drop them or keep them; it may merge them, etc.

The used_mmap variable was set to true the first time an mmap operation
was successful, but it was never reset back to false. While that can be
a good indicator that future calls might succeed it is not a guarantee.
Not properly resetting could mean we'd unmap memory allocated with new,
instead of deleting it.
Since that variable is only used inside defined(QT_USE_MMAP) blocks, its
declaration is scoped the same way.
While mmap is still handled "by hand", use QFile for the other
operations. Calling mmap here is less than ideal, as it prevents use of
other memory mapping methods, such as native Windows APIs, but is less
intrusive as it allows QTranslator to retain control over lifetime of
the map. Using QFile for remaining operations reduces the number of
filesystem operations.
The file size is now checked to be minimally sane (<4GB), the limit of
the 32-bit variable that will hold mapping's length. Translation files
should be expected to be much smaller in practice, but there isn't a
sane hard-limit. The file format is broken down to sections, each of
which has a 32-bit length.
Finally, when loading a file fails, release resources immediately,
instead of delaying to next load attempt or the destructor.
