ab5795e75c Bug 1317642 Disable WeakPtr thread assertions on MinGW r=froydnj
MinGW has two threading models: win32 API based, which disables std::thread,
and POSIX based which enables it but requires an emulation library (winpthreads).

Rather than attempting to switch to pthread emulation at this point, we are
disabling the std::thread based assertion checking for WeakPtr on MinGW.

4e6d8f6705 Bug 1207245 - part 6 - rename nsRefPtr<T> to RefPtr<T>; r=ehsan; a=Tomcat
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout.  The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.

CLOSED TREE makes big refactorings like this a piece of cake.

bf7f6dda03 Bug 1207245 - part 3 - switch all uses of mozilla::RefPtr<T> to nsRefPtr<T>; r=ehsan
This commit was generated using the following script, executed at the
top level of a typical source code checkout.

 # Don't modify select files in mfbt/ because it's not worth trying to
 # tease out the dependencies currently.
 #
 # Don't modify anything in media/gmp-clearkey/0.1/ because those files
 # use their own RefPtr, defined in their own RefCounted.h.

 # |using mozilla::RefPtr;| is OK; |using nsRefPtr;| is invalid syntax.
find . -name '*.cpp' -o -name '*.mm' | xargs sed -i -e '/using nsRefPtr/d'

d25f065cb3 Bug 1207245 - part 1 - move RefCounted<T> to its own file
Various bits depend on RefPtr.h to provide RefCounted<T> and RefPtr<T>.
It will be easier to manage an automatic conversion from RefPtr<T> to
nsRefPtr<T> if we split out the dependency on RefCounted<T> first.
