FX_BOOL was a type just like a regular C++ bool, except that it
took 4x the space and frequently was used to hold values besides
true or false.

The embeddertests were closing the document before the formfill environment.
This caused a use-after-free as we try to use the document during formfill
destruction.
This Cl fixes the destruction order in the embedder tests. As well, a few guards
are put in place to keep the system from crashing if the wrong destruction
order is called.

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.

Each annotation has its contents, and users should be able to see the
contents. In this patch, PDFium creates a Popup annotation for each
annotation and stores the author and the content. When a user mouse
hover on the annotation, PDFium draws the corresponding Popup annotation
and displays the content.
Also, roll DEPS for testing/corpus to 5867fa6.

In [1], it was made a mistake in the way the test case
testing/resources/pixel/bug_492.pdf was generated.
This CL aims at fixing this mistake by:
1- keep making use of the new pdfium_test capability
introduced by [1],
2- add a proper .in file for the test case to generate
its respective .pdf file.

In [1], the lack of support of pdfium_test to some application
level hooks was felt.
More specifically, the lack of implementation of the hook FFI_GetPage,
called when 'this.getAnnot()' is executed in an Acrobar JS context,
makes it non-trivial to JS texts that manipulate PDF annotations.
[1] https://codereview.chromium.org/2265313002/
Here is the failing call stack in pdfium_test:
0 ::RenderPdf (samples/pdfium_test.cc)
1 ::FORM_DoDocumentOpenAction (fpdfsdk/fpdfformfill.cpp)
2 CPDFSDK_Document::ProcOpenAction (fpdfsdk/fsdk_mgr.cpp)
3 CPDFSDK_ActionHandler::DoAction_DocOpen (fpdfsdk/fsdk_actionhandler.cpp)
<----v8---->
4 Document::getAnnot (fpdfsdk/javascript/Document.cpp)
5 CPDFSDK_Document::GetPageView (fpdfsdk/fsdk_mgr.cpp)
6 CPDFDoc_Environment::FFI_GetPage (fpdfsdk/include/fsdk_mgr.h)
(frame 6 returns nullptr, and getAnnot call in frame 4 bails)
CL extends pdfium_test app with a FFI_GetPage hook implementation.
Basically what FFI_GetPage does is returning a FPDF_PAGE instance.
In case of pdfium_test, FPDF_PAGE instances were only created on demand
when the page was going to get rendered, and then discarded.
Since FFI_GetPage can be called by JS before pages are rendered,
CL moved the page creation code into a helper function, and cached
the FPDF_PAGE instances created in a map, so it does not recreate
them needlessly.

Embedder test's delegate function GetPage() calls FPDF_LoadPage() to
load a page which may be already loaded by embedder test itself.
Thus the page's ref count is increased unnecessarily.
This causes the page to be leaked. Fix this by putting the page map in
embedder test class and guarantee the page is loaded only once.
Also, fix leaks in this embedder tests by unloading the loaded pages to
properly release the resource.

The PDF specification [1] says:
"
syncAnnotScan guarantees that all annotations will be scanned
by the time this method returns.
(..)
Normally a background task runs that examine every page and
looks for annotations during idle times.
"
The statement details specifically how Acrobat implements
this method.
Although, neither the method itself nor the background scanner
task are implemented in PDFium (as of today, Ago/2016),
not having ::syncAnnotScan at least stubbed out can be considered
harmfull since its absence makes JS acrobat scripts silently
fail when it has a call to it.
Given that, and following a stub-out pattern present in other
methods including ::addAnnot and ::addField, CL provides
a stubbed out implementation of Document::syncAnnotScan.

CL implements the first step in order to support
Annotations manipulation in PDFium: Document::getAnnot.
The method takes two arguments, an integer (page number)
and a string (annotation name).
When called, it iterates over the annotations on
the given page number, searching for the one whose name
matches the string in the second parameter.
If found, then an Annot instance (see Annot.cpp/g added by this
CL), is bound to a Javascript object and returned.
With the use cases described in bug [1] as an initial test case,
CL adds support to the following Annotation object properties:
- hidden
- name
- type
Idea is to keep evolving the implementation with more methods
and properties in follow up CLs.

Now that PDFium supports drawing of more annotation
types, it should also respect the "hidden" flag that
annotations might feature.
For instance, in IE/Acroread if an annotation is flagged as
"hidden" it does not get drawn.
CL adds a check for the specific "hidden" flag, not drawing
annotation that are flagged with it, in order to match IE + acrobat
reader behavior.
The "flags" definition can be seen by looking at "/F {value}"
syntax in a PDF file source, where {value} is an predefined
integer value.
Test: PDF files being added in [1].

Nearly all the "loose" functions in FXJS become methods on
the CFJXS_Engine.
This is the "missing link" wrt some layering violatons that
have been around forever. We can stop passing &m_ variables
from CJS_ down into FXJS Initialization as a result.

Create a new class to hold these, CFXJS_Engine (could have been
called Runtime, but there are too many "Runtimes" already). In a
subsequent patch, all the FXJS_*() functions that take an isolate
as the first argument can become methods on the engine.
CJS_ must still manage the isolates; this happens outside
the engine.
The IJS_Runtime abstraction moves up to fpdfsdk/javascript; it
remains to allow for either a real JS library or a stubb one to
be linked (for non-js builds).

Patch implements the Document's API gotoNamedDest, which is
part of the PDF specification [1], page 129, with the following
(short) description:
"Use this method to go to a named destination within the
PDF document".
[1] http://partners.adobe.com/public/developer/en/acrobat/sdk/5186AcroJS.pdf
"Named destination" is a common concept in the PDF world.
It can be used together with PDF's Links, Annotations, Bookmarks
and OpenActions, as well as an action per se, in case "this.gotoNamedDest"
is called directly.
Note that the implementation makes use of the existing hook
CPDFDoc_Environment::FFI_DoGoToAction, which ends up calling
out the embedder to actually handle it.
In case of Chromium, for instance, it calls PDFiumEngine::Form_DoGoToAction
which only handles for now the "page" property of the "destination".
Other properties, including zoom level, and scroll position
are ignored for the moment.

Fix memory ownership model for PDFium timers.
The |app| class owns the CJS_Timer as part of its vector<unique_ptr>
to them.
The CJS_Timer "owns" its slot in the global ID to timer map, and
removes itself when it is destroyed. Nothing else deletes
from the global map. Deleting from the global map is
accompanied by a callback to the embedder to clear its
resources.
Next, the proper way to remove a CJS_Timer is by going
through the app, and having the app erase its unique ptr,
which then deletes the CJS_Timer, which in turn cleans up the
global map. Provide a CJS_Timer::Cancel static method to
do this conveniently.
There is a alternate path to the CJS_timer via JS and its
CJS_TimerObj. CJS_TimerObj owns a TimerObj that currently
points to the CJS_Timer. If the timer fires, and cleans
itself up, this can go stale.
Make the TimerObj maintain a weak reference via global
timer ID rather than a direct pointer to the CJS_Timer, so
that if the timer fires and is destroyed, future attempts
to cancel find nothing.
There is another path, where if the JS timer object is GC'd, then we
just clean up its CJS_TimerObj without touching
the actual CJS_Timers. We could make this match the spec
by calling into the new cancel routine as described above,
but it seems weird to have a timer depend on whether a gc
happened or not.
A subsequent CL will rename these objects to more closely
match the conventions used by the other JS wrappers.
