Building a little-endian n-byte value via a single byte

More straight forward than CFX_GEModule owning in and CPDF_ModuleMgr

Remove assumptions that the codec modules may return nullptr, and do

The ToUnicode map should not be ignored when it exists. Doing so can cause a

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.

When decoding the CPDF_HintTable we read the dwDeltaGroupLen value out
of the input stream which is a 16bit number. That value is then passed
in to read a uint32_t of the object number. If we have a group length of
> 32 bits we'll cause an undefined shift when we attempt to shift right
more then 32 bits.
This Cl bails out early if the dwDeltaGroupLen value is > 32 in order to
stop the undefined shifts.
