This patch mainly consists of two parts, one for resolving and the other
for reordering.
In the resolving part, the added code stores the lowest embedding level
of all bidi formatting characters precede a frame to the bidi data of
that frame when necessary.
In the reordering part, virtual frame is restored from the information
stored above before asking the bidi engine to reorder frames
Collapsing a run of continuous virtual formatting characters into one
virtual character with the lowest embedding level among them should work
because a character with a higher embedding level than either of its
neighbors should not affect the reordering result of any other part of
the sequence. (No formal proof of this theorem, though)

This patch is mainly based on smontagu's wip patch. Some non-trivial differences:
* BidiParagraphData.mIsolateCount and related code are not added in this patch.
I investigated uses of this field in the wip patch, and it seems to me none of
them makes sense:
1. in the fast path of nsBidiPresUtils::ResolveParagraph, if there would be
any isolate character in the surrounding text, there must exist more than
one runs, which indicates the isolate count condition is redundant.
2. in handle of br frame in nsBidiPresUtils::TraverseFrames, based on my
understanding of "CSS Writing Modes Level 3" section "2.4.4. Paragraph
Breaks Within Embeddings and Isolates", the resolving should happen
unconditionally.
* {control,override}Char in nsBidiPresUtils::TraverseFrames are assigned
unconditionally when in a bidi inline container, so that we can properly
handle it when there are continuations. I suspect this was the reason of
regressions in dynamic reftests from the wip patch mentioned in comment 1.

To optimize copy of text rect array, we should use mozilla::Move. Also, after using it, we should mark is invalid result into SetEventResult

To test eQueryCharRectArray, I would like to add it to nsIDOMWindowUtils. Also this require unit test and will require external keyboard support on Android
Masayiki asks me more review to smaug this due IDL change.

Masayuki suggests GetCharcterRectsInRange instead of first idea's API by part 2 implementation.
IME wants to need the width per character. Now nsTextFrame/nsIFrmae has only API to get point of string. So I want to add this method to calculate simply by comment #3.
If no text frame, I would like to return error due to no character. (Caller shouldn't call this API on non-text frame.)
