Add Mac type conversion functions to QtCore
New API:
static QString QString::fromCFString(CFStringRef string);
CFStringRef QString::toCFString() const;
static QString QString::fromNSString(const NSString *string);
NSString *QString::toNSString() const;
static QUrl QUrl::fromCFURL(CFURLRef url);
CFURLRef QUrl::toCFURL() const;
static QUrl QUrl::fromNSURL(const NSURL *url);
NSURL * QUrl::toNSURL() const;
Add Q_OS_MAC-protected function declarations to header
files, add implementation to _mm files.
CF and NS types are forward-declared in the header
files to avoid including the CoreFoundation and Foundation
headers. This prevents accidental use of native types
in application code. Add helper macros for forward-
declaration to qglobal.h
Add cf_returns_retained/ns_returns_autoreleased attributes
to toCFString() and toNSURL(). These attributes assists
the clang static analyzer. Add Q_DECL_ helper macros
to qcompilerdetection.h.
Add test functions (in _mac.mm files) to the QString
and QUrl tests. Split out the test class declarations
into a separate headers files.
