We can get into a loop when gif_img_row_bytes is 0 since Decode will
return 3 when the second parameter is 0, and there is a while(ret!=0).

It already has a sizeof() and a cast built into the macro,
so we don't need to do sizeof() and cast on each usage.

The code_size variable is the number of bits. We should make sure that
the size is at most 31 to avoid having undefined shifts etc.

|code_size_cur| could be larger than |code_size|, so |code| could be
larger than |code_end|. If this happens, early return, since the Decode
has failed.

We allocate the GifPlainText object on line ~685 inside GIF_D_STATUS_EXT_PTE.
We cleanup the internal pointers in the gif_destroy_decompress() but we
failed to cleanup the pointer itself.
This CL frees the allocated pointer once the data is cleaned up.

This change contains files in core directory which were not covered
in part I. This is part of the efforts to make PDFium code compilable
by Clang chromium style plugins.
The changes are mainly the following:
-- move inline constructor/destructor of complex class/struct out-of-line;
-- add constructor/destructor of complex class/struct if not
explicitly defined;
-- add explicit out-of-line copy constructor when needed;
-- move inline virtual functions out-of-line;
-- Properly mark virtual functions with 'override';
-- some minor cleanups;

The code has local variables that shadow struct or class member
variables. Also, when this happens, different variable names should be
used instead of namespaces.
These were discovered by /Wshadow warning flag in Clang.

Use the more standard name "clear()" instead.

It isn't buying us anthing, and it looks strange in
a struct when other uint types are already present.

This CL moves the core/src/ files up to core/ and fixes up the include guards,
