Pass in/out argument as a pointer.
Avoid pointless malloc just to copy in multibyte case. Then we can
avoid special-casing the single-byte case.

- All callers of CFX_DIBitmap methods use nullptr as the ICC Transform.
- The CFX_ScanlineCompositor is always initialized with a null ICC transform.
Many of its methods call TranslateScanline from the ICC module. This method
casts just uses ((CLcmsCmm*)pTransform)->m_hTransform, and this should not be
done when pTransform is nullptr.

When fixing https://crbug.com/672177 we added a guard that we aren't
reading off the end of the file. That guard used the file access
Position(). This is the wrong value to compare against as our read
position and the file access Position may be different. This CL updates
the check to use the correct current file position.

CloneNonCycle() tries to detect cyclic object references without copying
them. There are two issues:
-- for elements in an array or a dictionary, they should be able to
refer to the same object, which are not cyclic;
-- for cyclic referenced elements in an array or a dictionary, do not
clone the element at all. Having nullptr or <key, nullptr> as an element,
like we did before, might cause crash when the element being accessed.
