In most cases, we just CHECK() that no exception was thrown. Previously,
we'd just crash.
Ideally, this should all be fixed and the system should cope with those
exceptions, but that's beyond this CL.

Phantom handles allow for freeing objects with one pass of GC. However,
this means that by the time the callback is invoked, the v8 object already
does no longer exist. To avoid accidential access to the dead object, there
are now two callbacks, where the first must only reset the handle, and the
second does the clean-up work.

PDFium side of fix to make chromium free of private header
includes. This moves the one snippet of contaminating code

These are the only files that embedders of PDFium should be including.
They are entirely self-contained, and compile cleanly against -Wall so
as to not offend the code that may include them.
Having done this, we can see that chromium is pulling in two additional
files from the fpdfsdk/include/pdfwindow directory, which is not guaranteed
to work.
A few files are renamed, adding an "_" to make the names consistent.
The exception is fpdfview, which is doc'd as such in the doc.
Naturally, paths will need updating in a handful of files in chrome
when this rolls in.

These flags are unused in Chromium, but are needed for the Cloud Print
conversion process, which takes PDF and produces a raster for low-end
printers. Certain low-end printers (e.g., B&W laser printers) will
turn anti-aliased text into a mess. The existing printing flag isn't
sufficient, as other kinds of printers will still want some kinds of
anti-aliasing to occur for best results.

This allows PDFium to work with current V8, so unpin v8 in the
pdfium DEPS file.
(I also re-ordered one field in CJS_Runtime, just to put two bools
together (may pack tighter), and to put all the v8 stuff together).

The code to validate the number of parameters happens inside each particular
method, rather than prior to method dispatch. As such, there's no point in
having this number take up space in the table.
Add some test to cover at least some of the per-method validations, and
update error messages to be more useful.

The red-flag here is the explicit invocation of things like
params[1].operator CFX_WideString()
rather than
static_cast<CFX_WideString>(params[1])
to invoke the conversion. Turns out the above won't compile due to
ambiguity given the number of implicit constructors for widestrings.
CJS_Value has both constructors and assignment operators for the
primitive types, which means that conversions can take place
unexpectedly in both directions, a second red flag.
We don't want the compiler invoking these at will since it may hide
bugs. In fact, when they are removed, three such places were
discovered.
Also rename ToJSValue to ToV8Value to match the other ToV8xxxxx
functions added.

CFX_Object is a type that implements its own new operators that return
NULL on error. There's no need for this given the |new (std::nothrow)|
syntax; in fact, the current code can only work if there is no activity
in the constructors. This may explain the pervasive lack of
constructors and reliance on Init() methods throughout the codebase.
The activity takes place in fx_memory.h, where FX_NEW is mapped onto
the std::nothrow syntax. The rest is just cleanup.
Down the road, we will simply throw and remove all the error-checking
paths for new objects. Landing this patch first will at least show a
simple path back to the old behaviour without having to re-introduce
CFX_Object should someone want to do so in their own fork.

This implements the previously unimplemented JS_Error() function.
Along the way:
- fix some IWYU when the include order in global.cpp was perturbed.
- remove some uses of JS_ErrorString, to increase transparency.
- use vp.IsSetting() in place of !vp.IsGetting() for clarity.
- specify an error string on several error return paths.
- add an error string for writing readonly properties.
- rename an error string constant to reflect the actual message.
- replace calls to variadic Format() with a function doing string appends.
- remove unused JS_GetClassName()

Along the way, I noticed that one of these is used in a header file
that isn't included anywhere and describes no actual code (JS_Console.h).
Also add missing header guards, and IWYU to resources.h
Also move a static function from a header to the new resources.cpp file.
Also fix the grammar on some of the error messages. Most of these
appear to be JS error messages destined for a JS error handler or (someday)
a console (which can remain in english), and oddly, some appear to be about
failed form validation, which smells user-facing.
Also check that the message makes sense for the point the C++ code
wants to use it, and reword accordingly.
As it turns out, these currently don't make it back to JS due to the
unimplemented JS_Error() function; this is an enabling step towards
implementing it.

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.

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.

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).

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.

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.

Warning from /analyze was:

Other error paths can also lead to reading from an uninitialized _FX_SYSTEMTIME object.
Code-gen for the constructor is small enough (four writes of zeroed EAX with VC++, less with gcc) to make putting the constructor in a .cc file unnecessary.
Approval of in-class member initialization would make this fix simpler but that has not quite been approved yet.

Should there be cases where this fails to compile, it indicates a mistake,
either an incorrectly declared overrriden virtual method, or a method that

The only issues were with CPDF_CustomAccess::GetBlock(), CPDF_CustomAccess::GetByte(),
