In the meantime, let's get rid of the platform specific ugliness here.

Implemented the new <search> HTML element.
All WPT tests for it now pass (except one for iso-8859-8, not done generally).
A11y role uses just landmark as recommended instead of a new search role (for now).

get_selections is largely based on the old IAccessible2_3::get_selectionRanges method.
However, this makes use of HyperTextAccessibleBase::CroppedSelectionRanges, which didn't exist before.
It has also been updated to return IAccessibleText pointers as required by the new interface.
setSelections is entirely new, but relies on existing mechanisms to convert offsets and to add and remove selections.

This patch does several things:
1. Remove virtual cursor doc accessible member.
2. Remove state-keeping nsAccessiblePivot implementation and replace it
with something that is much more similar to the native Pivot
interface.
3. Move nsIAccessiblePivot implementation to xpcom and rename it
xpcAccessiblePivot.
4. Delete mochitests and introduce browser tests.
5. Make new xpcom implementation work on remote accessibles as well.

This revision changes our focus event and anchor scroll handling to fire
scrolling start events for non-interactive targets, where "non-interactive" is
defined as "any generic, landmark, or region Accessible." This revision also
adds a test to verify that the scrolling start event is fired.

1. nsAccUtils::DocumentFor might return null if the Accessible is being moved and a client queried it during the move.
2. ChildAtPoint might return null if the point can't be located at all.

Now that the local-only TableAccessible and TableCellAccessible have been removed, we no longer need this Base suffix for the unified classes.
Aside from renaming the header files, most of the rest of this was done with the following script:
```
function replace {
sed -i 's/'$1'/'$2'/g' `git grep -l $1`
}
replace TableAccessibleBase TableAccessible
replace TableCellAccessibleBase TableCellAccessible
replace AsTableBase AsTable
replace AsTableCellBase AsTableCell
```

We now use CachedTableAccessible for ARIA tables and grids, so most of the code in the ARIA table classes was unused.
1. Remove ARIAGridAccessible and ARIARowAccessible completely.
2. ARIAGridCellAccessible no longer derives from TableCellAccessible.
3. Remove most of ARIAGridCellAccessible.
4. We still use ARIAGridCellAccessible to differentiate between valid and invalid cells. Valid cells create an ARIAGridCellAccessible and ARIAGridCellAccessible::IsTableCell() returns true due to mGenericTypes. Invalid cells don't get an ARIAGridCellAccessible, so IsTableCell() returns false on those.
5. We also keep the code in ARIAGridCellAccessible to expose some states and attributes.
6. The code for creating ARIAGridCellAccessible in CreateAccessible has been refactored, both for simplification and to fix bugs. display: contents tables now properly get the table and table cell interfaces; i.e. IsTable() and IsTableCell() return true when appropriate. Walking non-generic ancestors should fix ARIA tables with intervening generics, though this will be dealt with fully in a separate bug.

We now use CachedTableAccessible for HTML tables, so much of the code in the HTMLTable*Accessible classes was unused.
However, we still depend on these classes for some data needed to build the cached table.
1. HTMLTableAccessible and HTMLTableCellAccessible no longer derive from TableAccessible and TableCellAccessible, respectively. Instead, callers which need specific access to HTML table data use the HTMLTable*Accessible class directly.
2. All table specific methods have been removed except those that provide data required to build a CachedTableAccessible. The remaining methods are those for querying the row/column span (which depends on layout) and getting the caption (which depends on DOM).
3. HTMLTable*Accessible are now used for all <table>, <td>, <th> and <tr> elements and MathML equivalents. ARIA*Accessible are never used for these elements. This improves consistency, simplifies the code and means that behavior specific to these HTML elements is handled in these classes, rather than in the ARIA classes as well.
4. The table and row roles are now specified in HTMLMarkupMap and MathMLMarkupMap, rather than overriding NativeRole. Cell roles are still handled in a NativeRole override; see the code comments for details.
5. IsProbablyLayoutTable has been moved from TableAccessible to HTMLTableAccessible, as it is only relevant for HTML tables, not for ARIA tables.
6. HTMLTableHeaderCellAccessible::NativeRole has been rewritten such that it no longer depends on querying table coordinates, as that would now require building a CachedTableAccessible, which would be very wasteful here. This replaces TableCellAccessible::HeaderCellRole, which has been removed.

LandmarkRole always returns static atoms anyway, so formalize this.
