This is much faster than using a stringstream for a couple of reasons:
1. ostream needs to do a virtual call on each write which means that
it can't be inlined.
2. stringstream needs to check for resize every write(). We combine
those checks into a single one.
We create and destroy ScaledFonts for every piece of text we write.
That causes a huge amount of duplicated data within the recording.
This splits out the recording of the font data itself from the ScaledFont.
The key generated to determine uniqueness could probably be fairly easily faked, but for our purposes that doesn't matter.
This is so we can create the real print DrawTarget from our nsDeviceContext at the beginning of each page.
Default behaviour for other Translators is still to always use CreateSimilarDrawTarget.
This also changes aPrintToFileName parameter for BeginDocument to an nsAString& from char16_t*.
Having a char16_t* caused a pain with VS2105 where wchar_t != char16_t (as on VS2103), after it had been sent over IPDL.
This could have been worked around with casting, but this seemed like the tidier solution.

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.
