For now, always pass null, except when passing it through from one
overload to another.

This is the main performance improvement, and means that we no longer have to iterate all the cells for each column.
It has a couple of behaviour changes:
The first is that we no longer apply stacking context effects (like opacity) to column and column group backgrounds.
I believe this is correct as per both CSS2.1 Appendix E, and css-tables-3 (quoted in nsTableColFrame::BuildDisplayList).
This matches the behaviour of blink and WebKit.
We also previously created items in column,row ordering, whereas now they will be in row,column. In cases where two cells
overlap (using rowspan and colspan to extend multiple neighbours in to the same place) this can render backgrounds in a
different order, but the new behaviour matches blink and WebKit.

This helps for the next patch, since some of the table backgrounds items want to compute this without position:relative taken into account.

This also changes behaviour a bit, previously we interleaved column and column group backgrounds. where we now put all the column group backgrounds behind all columns.
I believe this is the correct ordering as per CSS2.2 Appendix E.
Column backgrounds can overlap when using 'span', and we now render this in a different order, but this matches what other browsers do.

Most of the code in DisplayGenericTablePart was all within a per-class if statement, so it doesn't add much value, and makes the control flow harder to understand.

This patch moves some `enum` in `nsIPresShell` which are in public scope into
`mozilla` namespace and change them as `enum class`es.
Unfortunately, only "where to scroll" enum is just defines constants of
percentages of scroll destination. Therefore, this patch makes only them
as `static const`.

Additionally, this patch makes `nsFrame.h` stop including `nsIPresShell.h`
and makes each users include `mozilla/PresShell.h` instead. So, this improves
rebuild performance of `nsIPresShell.h` (and `mozilla/PresShell.h` in the
future).
Note that due to `nsIFrame::PresShell()`, `mozilla::` prefix is necessary for
`PresShell` in a lot of classes which are derived from `nsIFrame` even in
`.cpp` files.

`nsPresContext` should use `mozilla::PresShell` directly instead of
`nsIPresShell`. This patch makes it.
Unfortunately, `nsPresContext` and `nsIFrame` have `PresShell()`. Therefore,
we cannot use `PresShell*` in its methods so that this patch uses `mozilla::`
namespace prefix.
It might be better to rename them as `PresShellPtr()` in another bug.

Really sorry for the size of the patch :(
Only intentional behavior change is in the uses of HasLengthAndPercentage(),
where it's easier to do the right thing. The checks that used to check for
(IsCalcUnit() && CalcHasPercentage()) are wrong since bug 957915.

This patch isn't expected to change behavior; it's just some simplification.

This patch is an automatic replacement of s/NS_NOTREACHED/MOZ_ASSERT_UNREACHABLE/. Reindenting long lines and whitespace fixups follow in patch 6b.

nsReflowStatus::IsEmpty() assertions are added after DISPLAY_REFLOW in the
beginning of the Reflow().
A few Reflow() implementations have Reset() calls at the end which are left
in place by this patch (with an explanatory comment added to each). These
ending Reset()s are only needed for cases where a non-splittable frame
passes its own nsReflowStatus to a child's reflow method. Just in case the
child leaves a "not fully complete" value in the nsReflowStatus, the
non-splittable parent frame must clear out the nsReflowStatus before
returning, so that its own parent doesn't then try to split it.

For the most part, I tried to make less *manual* table invalidations
for non-border-collapse tables and relied the table invalidations on
the comparison of the display items. By doing so, we can avoid the
over-painting issue.
