Jesus Fernandez 346cd79192 Make QFile::open fail when using an invalid file name
Fixes the bug in QFile which allowed opening a file with reserved
characters in its name.  If the name is a long file path, CreateFile
opens a file with a truncated name instead of failing, so we have
to catch reserved characters ourselves.

[ChangeLog][Windows] Fixed a bug that caused QFile to create
files with truncated names if the file name was invalid. Now,
QFile::open correctly fails to create such files.

For the windows file system engine, we add an extra macro to use
library loading if configured to do so, but avoid it on WinRT, as
none of the symbols would be found.

We also QT_REQUIRE_CONFIG(library) in the library headers and
exclude the sources from the build if library loading is disabled.

The 'rules' vector is made up of all the individual {env,config,...}Rules
vectors under mutex protection whenever init() is called (only from the
QCoreApplication ctor) or, at any time, by a call to QLoggingCategory::
setFilterRules().

Yet, the writes to the individual *Rules vectors were never protected by
registryMutex, racing against the reads of the same vectors in the
updateRules() function.

Fix by protecting all access of all member variables with registryMutex.
Add some strategic comments to make analysis easier for the next guy.

Sebastian Lösch da0241a2e7 Make variant selection possible if base is missing
[ChangeLog][QtCore][QFileSelector] Removed the requirement for an unused
default base file in case you want to load only a variant.

When the base file (e.g. /image.jpg) was missing, no selectors were
considered and it was not possible to load variants of this file (e.g.
/+android/image.jpg, /+android/+tablet/image.jpg) without specifying the
directory as well.

As a work around, one previously had to place a default file in
the base location, which is undesirable in some cases because:
1. The extra file consumes unnecessary space.
2. It is impossible to encapsulate platform-specific implementation
   details by hiding files in a subdirectory.

Giuseppe D'Angelo 6255cb893d Remove qtypetraits.h's contents altogether
So that QFlags can use an (un)signed int matching the
underlying type as identified by the compiler and not by us.

Requires fixing a few warnings about sign conversion due to
QFlags misusages in qtbase that were either plain wrong, or
were relying on the enum being backed by an (un)signed int
when it wasn't.

Keep qtypetraits.h in the source tree in order to prevent
source breaks if some downstream #includes it (note however
that it did not contain any public API).

Edward Welbourne 4b4bd6ab98 Simplify fileTimeToQDateTime() by having it return a UTC time
This avoids so many complications.  The prior code, using
SystemTimeToTzSpecificLocalTime(), lead to unhelpful results when the
QDateTime() implementation used MS-POSIX's defective mktime().
Although SystemTimeToTzSpecificLocalTime() is actually more correct,
we were getting inconsistent results by mixing the two: and
eliminating the use of mktime() turns out to be decidedly tricky.  So,
to avoid inconsistency, stick with a UTC time (which is what FILETIME
is defined as).  Change QFileInfo's methods to explicitly convert
.toLocalTime() where appropriate and document that these methods do
indeed return local time (as we conjecture has been taken for granted
by callers).

Also added a regression test for the reported case of this going
wrong.  A time-stamp from before Russia's (permanent, not DST) change
of TZ could end up inconsistently handled between file-system
meta-data and raw date-time APIs, due to cross-talk between different
MS-Win time APIs.

[ChangeLog][QtCore][QFileInfo] Made sure that all file lifecycle times
are in local time. This was probably true before, but is now explicit.

Elvis Angelaccio 3f455a4b53 Introduce QDir::isEmpty()
A directory is empty when it doesn't contain files or folders.
We can exploit QDirIterator::hasNext() to check whether this is the
case. This is efficient since it doesn't list the whole folder (in the
non-empty case).

Test cases are added for both the empty and non-empty cases.
