When there is a wrong keyword like '??ze' in the dictionary
of the trailer, PDFium can't recognize it and aborts further
parsing. After this change, PDFium continues even it can't
get the right size at this moment. It will rebuild the cross
reference table later since the size of the table is missing.

As we remove flate encoded sections from test cases (to
promote clarity), we should first have a simple unit test
for the underlying functionality.

Note that this work was done opposite the usual branch order, because I
didn't want to kill things in master that turned out to be in use in XFA.

Handles the case of this malformed PDF without crashing. Note that to
get a reproducible test case, a small fix is applied to our .py script
which results in some whitespace/numbering difs across the resources
(down the road, we ought to generate them on the fly in an intermediate
directory).

Any projects DEPS'd into chromium and requiring a /base
subset should have a local copy of that subset in a
separate namespace. This will avoid future naming conflicts.
Re-arrange the directory structure to better identify what
came from chromium's base, and to make drop-in replacement
easier for files that contain hard-coded "base/" in their
#include directives.

Headers in /include directories should be free of implementation details
from third_party. Put the types into a new header outside of /include.

This is part of the project to kill off C-style casts in the code base.
Remove implict T* cast operator, and replace potentially unsafe C-style
casts with Get() method.

While we're at it, avoid an indirection through a pointer, and
use a name that isn't reserved for the compiler (leading _ CAP).

A suitably corrupted file can cause the parser(s) to repeatedly re-read
sections of the file at increasing parser recursion depth until the
stack is exhausted. There is supposed to be a check for this based upon
the parser "level", but not all call paths pass or update the level as
required.
Much as I hate per-class statics, this introduces one to track the depth
so that the check is enforced no matter how screwy the call path might be
that leads the parser to re-enter itself. This is more palatable than trying
to find all these paths and fix them. We know this is OK since there is
only one thread in here modifying the static.

We are making checks in the incorrect order. Also adds two test
cases, one for the this crash, and another for the original issue
that motivated the patch.

Currently, no callers go through the Interface, which makes having a
separate interface class kind of pointless. After converting callers
away from using the CPDF_DataAvail concrete class, it can be moved
from the header to the .cpp file.

root object
Before this fix, the root will be released when an indirect object has the
same object number with the root. However, the root object is loaded when
the trailer is parsed. It shall not be updated or replaced anymore.

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.

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.
