None of these are currently reachable because the IsSafeMode
method always returns true. This, in turn, will let us kill
off some file (as in fopen()) based parsing. That, in turn,
will let us kill of some more now-unreachable code.
In general, we don't want to have unsafe modes.

Includes fixes to XFA specific warnings -- benign truncations.
Bug https://code.google.com/p/pdfium/issues/detail?id=104
was filed to track changing types to avoid some truncations.
Resolve all but two VC++ build warnings in pdfium.
pdfium builds on Win32 have about 85 warnings (250 in the XFA
branch, totaling over 480 lines!), mostly from four lines in
a header file and a warning that should be disabled. This
change resolves all but two of them and turns on
warning-as-errors. Bugs have been filed for the two
remaining warnings:
https://code.google.com/p/pdfium/issues/detail?id=100
the 64-bit warnings:
https://code.google.com/p/pdfium/issues/detail?id=101
and the Linux warnings:
https://code.google.com/p/pdfium/issues/detail?id=102
The fix to the double->float truncation bugs will also
improve code-generation.

Get rid of fifteen copies of m_sTimeMap and their initializers.
m_sTimeMap is a global variable with a constructor and destructor, which
is not allowed. This change moves it to a function with a static pointer
so that it is constructed on demand and then leaked, thus avoiding
having startup and shutdown code.
This also fixes a worrisome bug caused by having m_sTimeMap defined in
a header file. Because m_sTimeMap was defined (and marked as static) in
a header file there were fifteen separate copies of it, one for each
source file which included the header file. This could easily lead to
bugs because a timer that was added from one source file would be
invisible to other source files.
Each instance of m_sTimeMap added four entries to the
dump-static-initializers.py report, for a total of sixty, so this fix
significantly cleans up that report.

Note that the merge of this fix to XFA found six bugs. Five
were fixed in https://codereview.chromium.org/826573003 and
one was fixed in https://codereview.chromium.org/831293002.
These bugs are now impossible to compile.
Replace manual/error-prone/hard-to-verify arraysize calculations with
safe 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.

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.

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).

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.

There are many warnings that look like:
error: 'CPWL_RadioButton::OnChar' hides overloaded virtual function [-Werror,-Woverloaded-virtual]
virtual FX_BOOL OnChar(FX_WORD nChar);
^
note: hidden overloaded virtual function 'CPWL_Wnd::OnChar' declared here: different number of parameters (2 vs 1)
virtual FX_BOOL OnChar(FX_WORD nChar, FX_DWORD nFlag);
^
It looks like someone added the nFlag parameter to the methods in CPWL_Wnd
at some point and missed to update all overloads This patch attempts to fix this:
It adds the parameter to all methods that look like they're trying to overload the base
class method, and renames the method in one case where it fairly clearly looks like
that it's not supposed to be an overload.

On Windows, I believe MSVS treats these as override since it's such a common and
easy mistake, but clang and gcc do what the standard specifies. Add a "const" to
the function in the subclass so that this is actually an override, as intended.

If somehow different length values could be obtained by two successive calls
to Doc_getFilePath() (and FieldBrowse() for that matter), and the method is
true to the API documentation that says "The return value always indicated
number of bytes required for the buffer, even when there is no buffer
specified, or the buffer size is less then required", then it is possible
to get a returned length describing memory beyond the current buffer.
We can make the corresponding JS_docGetFilePath() method more robust against
this case by applying better checks to the returned value.
This probably is unrelated since ASAN seems to be flagging the corresponding bug
as UAF, but doesn't hurt to make things more robust.
