cd63c6bfee Bug 1261735 (part 3) - De-virtualize nsIAtom::IsStaticAtom(). r=froydnj,erahm. 
This avoids the need for some virtual function calls and also will help lead to
distinct representations for dynamic and static atoms.

e4dec8d42f Bug 1261735 (part 1) - Overhaul the atom implementation. r=froydnj,erahm. 
This patch changes things so that dynamic atoms and static atoms have distinct
implementations. This is a step towards allowing dynamic atoms and static atoms
to have different layouts in memory, which will allow static atoms to be
represented more compactly.

Specifically, the patch does the following.

- It renames AtomImpl as DynamicAtom and PermanentAtomImpl as StaticAtom, and
  the latter is no longer a subclass of the former. This required duplicating
  some methods from the former into the latter: ScriptableToString(),
  ToUTF8String(), ScriptableEquals(), IsStaticAtom(). (This duplication will
  disappear in the future if the representations of dynamic atoms and static
  atoms diverge. Indeed, SizeOfIncludingThis() is already different in the two
  classes.)

- It replaces all mentions of "permanent"/"non-permanent" atoms with
  "static"/"dynamic".

- In ~DynamicAtom() it removes the check that causes gAtomTable to be deleted
  when it becomes empty. This will only happen at shutdown and so doesn't seem
  useful.

- It documents better various things, especially the basics of the
  dynamic/static split, the transmutation of dynamic atoms to static atoms, and
  the details of the SizeOf functions.

ecf24a2b78 fix for bug 195262: 
- convert atoms to UTF8 because 99% of the time, that is what they are used for
- add support for static atoms, where the strings are declared in a large const array and not copied into the heap
r=dbaron, sr=darin

this is an experimental landing - if there are performance issues, I will back it out.
