This avoids unchecked multiplications when computing a size argument
to malloc(). Such an overflow is very scary, and can result in
exploitable bugs.
Along the way, kill off some return checks, since we know this can't
return NULL.

Very few places where a change is required, but remove FX_NEW to show
they've been audited.

CFX_Object is a type that implements its own new operators that return
NULL on error. There's no need for this given the |new (std::nothrow)|
syntax; in fact, the current code can only work if there is no activity
in the constructors. This may explain the pervasive lack of
constructors and reliance on Init() methods throughout the codebase.
The activity takes place in fx_memory.h, where FX_NEW is mapped onto
the std::nothrow syntax. The rest is just cleanup.
Down the road, we will simply throw and remove all the error-checking
paths for new objects. Landing this patch first will at least show a
simple path back to the old behaviour without having to re-introduce
CFX_Object should someone want to do so in their own fork.

Whether ch and iRet are read without being initialized depends on complex
preconditions and cannot be determined by looking at these function.
Therefore it seems prudent to zero initialize them to avoid any risk.

m_pageObjects never gets initialize, thus making CPDF_PageContentGenerate::GenerateContent() doing nothing.
Since the CPFD_PageObject are owned by m_pPage, no need to release them in the destructor.

No intended behavior change.
- Remove more unused variables, functions, member variables.
- Put a few constructor initializers in the order they execute in.
- Add braces for subobject initializers.
- Fix a handful of signed / unsigned comparisons.
