CFXJS_Engine class should always be constructed with an isolate, except
for its subclasses which may need to create an isolate by themselves.
Move SetIsolate() function to be protected so that only subclasses can
access it.

Per isolate runtime data should be deleted when the associated
isolate's destructed.
Also, the internal of per isolate runtime data is obscure to the JS
engine. So XFA or this class itself has to be in charge of the memory
management. Use smart pointer for it so that the resource
could be released properly.

The m_pApp variable holds a CPDFSDK_Environment. This Cl renames the variable
to be m_pEnv so as not to confuse with the various App classes that exist.

We remove the indirect object holder argument and check that
call sites pass ownable objects, adding a reference in one
place that always was passing an indirect object.
Also check that the invariant isn't violated, we need to fail
here in the wild and investigate -- these are existing UAFs.

BUG=79367, 48791
The fonts was not cleared after unloading pages.
Test pdf: http://www.nasa.gov/pdf/750614main_NASA_FY_2014_Budget_Estimates-508.pdf
For this file, we have ~5 fonts per page, which equal ~1 Mb per page.
In this PDF we have 670 pages, as result after slow scrolling(reading) full document we have ~600 Mb fonts data in memory.
Memory usage of PDF Plugin:
before this CL: ~660 Mb
after this CL: ~100 Mb

Upon indirect object holder destruction, all indirect
objects are destroyed -- currently by order of increasing
object number -- but ideally without ordering constraints.
So currently, we can get away with a dictionary pointing
directly at an indirect object with a higher number. It
gets destroyed first, invoking Release() on its subordinates,
which skips destroying them if they are indirect objects. But
we don't want to rely on this artifact of destruction
order. Should it happen to be reversed, the dictionary
would invoke Release() on freed memory.
Interestingly, CPDF_Array skirts the issue by replacing
any indirect objects it is given with references. Not
clear whether we should do the same thing for dictionaries,
or remove it from arrays. The technique certainly
complicates understanding ownership.
The one violation found is in the unittest that broke the
previous CL which tried to use unique_ptrs in indirect
object holder.

If the --if-needed argument is passed to the clang update script then we depend
on GYP_DEFINES to be set in order to update clang. We no longer define
GYP_DEFINES so we fail to update clang (or checkout clang).

Replace the CPDF_Stream(nullptr, 0, nullptr) pattern with
a default ctor.
Remove unused parameters from CPDF_Stream::SetData(). Both
are always passed as FALSE.
CPDF_Stream declared its own m_GenNum, which shadowed the one
in CPDF_Object. It was used only to distinguish file/memory
streams, so add a bool explicitly for this purpose.
Remove the union, it would be sad if we confused user data
with a C++ object with virtual function calls.
Use unique_ptrs with appropriate deleters to manage memory.

PWL_FontMap does not need its own charset definitions. fx_edit.h does
not need to define DEFAULT_CHARSET. XFA have their own definitions.
They look different in that most are MAC or MSWin charset definitions.
So they are left untouched. public/fpdf_sysfontinfo.h duplicate ones
were left untouched due to being in public folder.

On Acrobat, if "/AP" is present on a text markup definition,
the coordinates used to draw the annotation come from "/Rect
values, whereas if "/AP" is not defined, the array defined
in /QuadPoints is used to grab the annotation coordinates from.
PDFium, on the other hand, uses "/Rect" regardless of
presence or absence of "/AP".
CL fixes PDFium to work similarly to Acrobat, in this case.

CPDF_Font::UnicodeFromCharcode returns 0 only if ToUnicode map maps the
charcode to 0. CPDF_SimpleFont::UnicodeFromCharcode and CPDF_CID_Font::
UnicodeFromCharCode return 0 only if the call to CPDF_Font returns 0.
In other cases, these methods return an empty string. So when
processing text, a 0 return from the method should not be replaced
with the charcode.
