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, this is a difference between the standalone pdfium environment
vs. pdfium as part of a chromium checkout.
Locating the external data files is a nusiance when you don't have the
binary's argv[0] line, so we create a new main that preserves this for
us.

This also adds a fpdfdoc_embeddertest.cpp to keep the test
file name matching with the API call under test.

Follow-on work from patch at https://codereview.chromium.org/845643008. This
incorporates that patch, plus adds tests for it and similar conditions. A few
changes are introduced to correct expected behaviour.
This also incoprorates Deepak's fix in https://codereview.chromium.org/845643008/
This incorporates a formerly unlanded tool to generate small valid PDF
files from template input, which is needed to cover all the error cases
here. See https://codereview.chromium.org/791993006/

This was somehow lost along the way to creating embedder tests. Presumably
this silently leaks in origin/master, but triggers an assert under XFA. Fixing
this on master is a pre-requisite for merging all the embedder test code onto
XFA.

This includes:
- Fix TestLoader lifetime.
- Rename test file to match the equivalent .cpp under test
- Re-organize a few tests to avoid duplicate loading
- add tests for a few additional functions.

This allows integration with the gtest EXPECT_* macros.

In order for the standalone pdfium build to succeed,
DEPS is updated to pull in gtest, and a stub gtest.gyp
file is provided (which is unused under a chromium
checkout).
