Remove handling of arbitrary function calls, and only allow supported
function calls. Issues with the lexer being overly permissive led to
large blobs of javascript being dropped into the output. Specifically
driver code was assuming that anything marked as a function would just
be an identifier that could be inserted into the javascript, but the
lexer marks things like ()()() as a function, which would lead to the
following JS being inserted as an identifier.
This change is intended to be a patch for the specific issue that was
being seen from the fuzzer test, and further work will be needed to
make the lexer more strict.

The new embedder test shows Oneof() works, whereas the corpus test does
not. It turns out the corpus test was bad, and trying to fix it exposed
a different bug. So roll DEPS for the testing corpus anyway to get
improved tests, but keep the suppression for now.

CFGAS_GEFonts are ref counted, and its a good thing since they
are managed by at least three different font managers:
CFGAS_FontMgr, CXFA_PDFFontMgr, and CXFA_FontMgr. None of these
have a clear claim to ownership of the CFGAS_GEFont.
CFGAS_GEFont has back-pointers to two of these, CFGAS_FontMgr, and
CXFA_PDFFontMgr, and they could each outlive the other. Thus the
font needs to watch for destruction of either of its managers, so
as to stop using it after its gone.

There are places where an object "child" has a raw pointer
back to object "owner" with the understanding that owner will
always outlive child.
Violating this constraint can lead to use after free, but this
requires finding two paths: one that frees the objects in the
wrong order, and one that uses the object after the free. The
purpose of this patch is to detect the constraint violation
even when the second path is not hit.
We create a template that is used in place of TYPE*. It's dtor,
when a memory tool is present, goes out and probes the first
byte of the object to which it points. Used in "child", this
allows the memory tool to prove that the "owner" is still alive
at the time the child is destroyed, and hence the constraint is
never violated.
