Loosen a check for earlier version of PDF files. When the bytes with
specified length are followed by 'endstream' keyword, even if there is
no EOL marker before the keyword, it signals the end of stream.

RebuildCrossRef function returns false when we can not find file trailer
or any indirect object. This serves as a basic file format checking.

This matches the type of the corresponding |CFX_DIBSource::m_Pitch|,
where integer overflow is checked for FX_DWORD. This change is
propagated to many other places.
Also, check for integer overflow in |CCodec_RLScanlineDecoder::Create|
during the calculation of |m_Pitch| since it aligns to 4 bytes while
overflow was was previously checked without this alignment.

During decoding, when an image decoder is encountered, any
subsequent decoders are ignored, but remain in the array. However,
later on CPDF_DIBSource::ValidateDictParam expects the image
decoder to be the last in the array, causing issues.
A check is also added in CPDF_DIBSource::GetScanline to ensure
that the calculated pitch value is <= the (4-aligned) pitch value in the
cached bitmap to prevent future issues.
Also cleans up some NULL usages.

CPDF_DIBSource::DownSampleScanline32Bit
Previously, if |m_bpc| was < 8 (e.g. 4), this function may still try to
access the source components as if |m_bpc| == 8. Even when it fell into
the codepath that tried to do the right thing in this case, it was
wrong.

The m_pShadingObj can be a stream or a dictionary depending on how it's used.
This CL adds some simple type checking to make sure that the type of the
object matches what we expect.

There appear to be a bunch of corpus tests which fail with this change such
as FAILURE: shading1.pdf
This reverts commit 85361b227ad6786d2aeef8409b79a8d077a26ee9.
Make m_pShadingObj a CPDF_Stream instead of CPDF_Object.
This object is required to be a stream and was being converted as such. With
the new type checking this caused us to pass a nullptr where previously we'd
have, incorrectly, cast a CPDF_Dictionary to a CPDF_Stream.
This CL changes the m_pShadingObj to always be a CPDF_Stream. Then, we never
go down the bad code path because we check if m_pShadingObj is nullptr earlier
and bail out.

For bit per component (bpc), PDF spec mentions that a RunLengthDecode or DCTDecode filter shall always deliver 8-bit samples. However, some PDF files don't follow this rule. We can find that filter is RunLengthDecode but bpc is 1 in the provided test file. In this case, pdfium will correct bpc to 8 but the actual bpc is 1. It causes a failure because the data is much more than the expected. To handle this case, pdfium doesn't correct bpc to 8 when the original bpc is 1.

Pdfium swallows 'fi' or 'ff' in some tested files because it doesn't load the embedded font file correctly. The root cause is that there is incorrect keyword like 'ngendstream' in the stream of the embedded font file. Pdfium tries to find another correct keyword but uses wrong offset rather than accumulated offset.

The current |bitpos1| calculation protects the passed argument to
_GetBits32(): |bitpos.ValueOrDie() + j * m_nBitsPerSample|, but doesn't
account for adding in the sample length in that routine.
Also bound bits per sample to something reasonable to avoid undefined
behaviour on the shift to compute the max value.

Reproducing this bug requires the embedder to fire timers, something the
single-pass pdfium-test binary doesn't do properly at the present. So
we modify the embedder test delegate to allow the immediate triggering
of the same.
Perform some cleanup along the way by removing EmbedderTestDefaultDelegate
-- it buys us nothing over the the no-op one.
And, of course, v8 initialization is busted again, and we need v8 here.

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.

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.

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()
