Getting rid of more (FX_LPCWSTR) casts and fixing two bugs revealed by this.
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.

Fixing operator so that bCheckRight isn't always true. Unknown effect!
VC++'s /analyze points out that this expression:
FX_BOOL bCheckRight = type != 'D' || type != 'W';"
is always true. This means that the tests for the right edge of a word

Zero initialize ch to avoid possible bug - conditions are very subtle.
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.

Update freetype to 2.5.4.
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

Add a small LRU cache for the JBIG2 symbol dictionary.
This reduces rendering time on my test document by over
10 seconds. It is super common for a JBIG2 dictionary to
span multiple pages, so we don't want to decode the same
dictionary over and over again.

Avoid duplicate definitions of JSCONST_n*Hash and QeTable variables.
QeTable is a 752 byte array that was defined in a header file. This
caused it to be instantiated by the VC++ compiler 12 times, wasting
8,272 bytes of space in the data segment. Because 'const' implies
'static' this did not cause any duplicate symbol errors.
JSCONST_n*HASH are a set of eight variables that are defined in a header
file. This causes them to be replicated 15 times. The variables
themselves are tiny but they are dynamically initialized and this
dynamic initialization code is replicated 15 times.
When tested on pdfium_test.exe the effect of this change is to:
Reduce the .text (code) segment by 3,616 bytes.
Reduce the .rdata section by 8,656 bytes.
Reduce the total binary file size by 13312 bytes.
These are the worst offenders for pdf.dll as shown in:
https://drive.google.com/open?id=1BvubxoA2SU_2e4T5cq7jHTjc1TlT0qOndpIfX3DMeA8&authuser=0
This will also drastically simplify the list of work to be done
for bug 441899 (getting rid of initializers).

Fix blank page issues caused by too strict check
Before this fix, PDF parser aborts the parsering process when detecting an error.
For this case, PDF parser just gives up parsering when it detects that the length of
image stream is incorrect. The solution to this case is to find the tag "endstream"
and "endobj" to calculate the length rather than aborting the parsering process.

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.

CPDF_StreamContentParser::Parse.
This is just a bit of defensive programming; I'm not sure the situation can
occur in the current code, but the following code is likely to set off a red
flag to anyone who reads it:
CPDF_StreamParser syntax(pData, dwSize);
m_pSyntax = &syntax;
since the extent of the local |syntax| is far less than the pointer member
|m_pSyntax|. NULL it out before syntax goes out of scope.

Before this fix, only |gindex < face->num_locations| is checked. However, the pointer, p, will be moved to next location in the first FT_NEXT_ULONG or FT_NEXT_USHORT. It may cause a crashier. So a boundary check is needed before the second FT_NEXT_ULONG or FT_NEXT_USHORT.
