This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

We call PDFiumParent::Close twice under certain conditions. Once in
PDFiumProcessParent::Delete, and once in PDFiumProcessParent's dtor. So we may
hit MOZ_ABORT which tell us that we are trying to close a closed channel.
This patch prevents hitting this abort by:
1. Only close the channel in PDFiumProcessParent::Delete, remove another call
in PDFiumProcessParent's dtor. (Please see the change in
PDFiumProcessParent.cpp).
2. Remove PDFiumParent::AbortConversion and relative code. We can just use
PDFiumParent::EndConversion instead. When calling PDFiumParent::Close, we
actually close the IPC channel *synchronously*, which means there is no need
to register a callback by PDFiumParent::AbortConversion to receive
actor-destroy callback.

While aborting conversion, we need to make sure there is no coversion task
executing in the PDFium process before destroying it.

Define ipdl and actor classes. Implementation of actors is added in subsequent
patches.
Control flow:
1. A user starts a printing job.
2. We create a PrintTarget to print web content page by page.
3. When printing pages:
a. PrintTarget, who lives in the chrome process, create a new FileDescriptor
and pass that FD to the content process.
b. The content process renders page contents into the given FD.
c. PrintTarget render that FD, which contains only one page, into a PDF
file.
d. PrintTaget asks PDFium process to convert that PDF file into EMF contents
by *ConvertToEMF*
e. The PDFium process converts the given PDF into EMF contents and send back
EMF contents by *ConvertToEMFDone*
f. PrintTaget playbacks that EMF onto a printer DC. One page is printed!
f. If all pages are printed, then finalize print job; Otherwise, loop back
to #a.
The control flow that we landed in bug 1370488 does not work like the flow
I described above.
In [1], we paint all pages into one single PDF file. After all pages are
rendered into this PDF file, we finalize the current print job, which means the
printing progress dialog is close. *Then* we start to convert that PDF into
EMF and print each EMF page onto printer DC. We can not cancel this conversion
task since the printing dialog is close, there is no UI allow us to do that.
One more serious problem is: since the printing progress dialog is close,
people think that printing is done, but actually it's not.
Except move EMF conversion to a dedicated process, named PDFium process, I will
also fix the behavior we landed in bug 1370488.
