These are the only files that embedders of PDFium should be including.
They are entirely self-contained, and compile cleanly against -Wall so
as to not offend the code that may include them.
Having done this, we can see that chromium is pulling in two additional
files from the fpdfsdk/include/pdfwindow directory, which is not guaranteed
to work.
A few files are renamed, adding an "_" to make the names consistent.
The exception is fpdfview, which is doc'd as such in the doc.
Naturally, paths will need updating in a handful of files in chrome
when this rolls in.

Should there be cases where this fails to compile, it indicates a mistake,
either an incorrectly declared overrriden virtual method, or a method that
should be declared non-virtual.
The only issues were with CPDF_CustomAccess::GetBlock(), CPDF_CustomAccess::GetByte(),
and CPDF_CustomAccess::GetFullPath(). These don't appear to be used anywhere,
and are removed. Two members are removed that are no longer needed once those
methods are removed.

Calling `delete` on an object of a type that has virtual functions but
not a virtual destructor is questionable: Since the object has virtual functions,
it likely has subclasses, so if it's deleted through the base pointer and the
destructor isn't virtual, the subclass destructor won't be called.
In most cases, the classes getting deleted can just be marked final to tell
the compiler that it can't possibly have subclasses (this also enables the
compiler to generate better code).
Two classes didn't have any sub- or superclasses but virtual functions -
this doesn't make sense, so make all methods of these classes non-virtual.
(Also delete an unused function on one of the two classes.)
In one case, a class actually did have a subclass that needs to be deleted
virtually, so mark one destructor as virtual.
