This reverts commit 090d683489bfa3f36f1e2624c310ff9ca5836038.
Symbol appears in files that are not compiled anywhere, it would seem.
Reverting to remove these first.

It's unused, and when the time comes, we'll want to put
pdfium onto a hardened allocator like partitionAlloc anyways.
Along the way, merge adjacent #ifdef __cplusplus blocks,
remove a pointless check for __cplusplus inside a .cpp file,
and remove a redundant cast.

I thought I had done this already, apart from the third-party
libraries, but there were a couple remaining (the third-party
libraries will still call this, they should be tweaked
upstream as needed).

Precursor to taking a second shot at cleaning up the FPDF_*
APIs. A FPDF_LINK is a CPDF_Dictionary, and a CPDF_Link
is a structure holding a FPDF_LINK. This goes against the
convention that FPDF_ types get cast to CPDF_* types, so we
want to make it clear where objects are getting constructed.

While we're at it, avoid an indirection through a pointer, and

A suitably corrupted file can cause the parser(s) to repeatedly re-read
sections of the file at increasing parser recursion depth until the
stack is exhausted. There is supposed to be a check for this based upon
the parser "level", but not all call paths pass or update the level as
required.
Much as I hate per-class statics, this introduces one to track the depth
so that the check is enforced no matter how screwy the call path might be
that leads the parser to re-enter itself. This is more palatable than trying
to find all these paths and fix them. We know this is OK since there is
only one thread in here modifying the static.

Currently, no callers go through the Interface, which makes having a
separate interface class kind of pointless. After converting callers
away from using the CPDF_DataAvail concrete class, it can be moved
from the header to the .cpp file.

Previously, UTF16LE_Encode take an optional flag to indicate
if the returned byte string has trailing zeros. In fact, no where
needs the flag to be false. So just get rid of it so callers won't
misuse.

This is done by explicitly adding a virtual dtor to interface classes,
since the cost is small given that there are already virtual functions.
The exceptions are for classes that have a Release() or Delete() method,
in which case it is non-virtual and protected to indicate that the virtual
class is never the deletion point.

Put freetype into third_party directory, cleaning up header files.
Previously freetype header files are in core/src/fxge/freetype and core/include/thirdparties. There were also multiple fx_freetype.h.
This patch removes the additional Foxit wrapper to make further update easier.
Notice, for original freetype source code, the following files are modified and need to be updated accordingly in future update:
third_party/freetype/include/config/ftmodule.h
third_party/freetype/include/config/ftoption.h

FX_ArraySize macro.
pdfium has numerous places where the number of elements in an array is
calculated with expressions like:
sizeof(cFormats)/sizeof(FX_LPCWSTR)
This is suboptimal because it is verbose, it is easy to get wrong, and
it cannot be determined through casual inspection whether the code is
correct. It will give incorrect results if cFormats is a pointer instead
of an array and it will give incorrect results if FX_LPCWSTR is not the
type of the array elements.
The FX_WSTRC macro in fx_string.h which I fixed was particularly scary
because it would silently misbehave if passed a pointer.
The FX_ArraySize macro which I have added and started using (taken from
arraysize in v8's macros.h) is easier to use and will always give correct
results. If passed a pointer it will fail to compile.
For this change I only fixed instances of sizeof(FX_LPCWSTR). There
appear to be about 150 other places in the pdfium code that could
benefit from using FX_ArraySize.

Since casts to FX_LPCWSTR have been shown to hide bugs I tried removing
more of them, targeting those places where a cast was used to force a
conversion from CFX_WideString to FX_LPCWSTR, replacing these casts with
calls to the newly added .c_str() function. This revealed two places
where the cast was hiding a bug -- where ->c_str() was required instead!
This removes ~33 FX_LPCWSTR casts and there are ~31 left, many of which
will go away in some future change.
Also includes this change:
Removing unnecessary casts from wchar_t* to wchar_t*, by various names.

As of the 2013 version VC++ still doesn't support the 'z' size specifier. This makes portable printing of size_t types frustrating. The simplest general solution is to use %u and cast to unsigned. If there was any possibility of the numbers getting larger than 32-bit then we would need better alternatives, but there is not.
This was found through code inspection, through /analyze, and through pdfium_test print this non-helpful message:
Loaded, parsed and rendered zu pages.
Skipped zu bad pages.
I can confirm that the fix works on Windows and it should work identically on mac. This is a follow-on to change 02e6ca4c4f.

Remove casts that merely cast from wchar_t* to wchar_t*. Sometimes the
types or casts are FX_LPCWSTR but the idea is the same. Excess casts
can (and have) hidden bugs so removing these may prevent future problems.

CPDF_Pattern objects are counted and maintained in m_PatternedMap.
When a CPDF_Pattern object "pattern" is deleted, it's address is marked as NULL in m_PatternMap.
This patch stores the address of CPDF_Pattern's adderss in all objects that references "pattern",
to ensure valid referencing after deletion.

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.
