The Gif module is only using the longjmp as a way to catch errors, so this CL
makes it use GifDecodeStatus::Error instead.

This CL adds some checks to make sure the DecodeString method does not go out
out control:
If code is equal to code_table[code].prefix, it will try to loop forever.
Even if that's not the case, avoid reading a negative position from the stack.

This CL changes the tag_gif_decompress_struct into CGifDecompressor. It cleans
up a bunch of unnecessary function pointers and starts cleaning up the members
of the new class.

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;

This CL moves the fxcrt code into the core/fxcrt directory. The only exception
was fx_bidi.h which was moved into core/fxcrt as it is not used outside of
core/.

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,
includes and build files.
