The fx_codec_jpx_opj code will attempt to do a 1 << (prec - 1). If the prec
value is >=32 then that shift will overflow the int value. This CL adds a check
that prec is < 32 before attempting the shift.

The JPX decoder needs to verify there is data associated with an image channel
before access. This was already done in one side of the if() but seems to be
missing from the other.
This Cl updates the loop to check the existance of channel data and to continue
iteration if none found.

FXSYS_round is painfully slow on Windows. It does range checking and
then calls an extremely expensive function. It ends up consuming half
the CPU time when decoding the images in PDFs such as this one:
https://www.ets.org/Media/Tests/GRE/pdf/gre_research_validity_data.pdf
SSE can be used to optimize this:
__m128 cmyk = {c * 255, m * 255, y * 255, k * 255};
uint32_t output[4];
_mm_storeu_si128((__m128i*)output, _mm_cvtps_epi32(cmyk));
but is cryptic, only works for x86/x64, and gives basically identical
performance to this solution - int(c * 255 + 0.5f);
The rounding behavior is not identical but in practice this rarely
matters, and in this specific case it does not matter because the edge
cases that vary are not hit.
The three divisions at the end were changed to multiplies because
profiling showed they were a significant cost.
This change reduces the image-decode stalls in the PDF listed above by
about 40%, making for a noticeably better experience. Further
optimizations are possible but would require significantly more time and
testing.

The ::DetectImageType method does more then just detecting the image type, it
also sets up various needed structures to handle the decoding. Instead of
skipping the ::DetectImageType call this CL changes the code to return early if
the image check fails. This should allow us to stop working on images which do
not match the required data format.

* PWL_Signature
* PWL_IconList

This change mainly contains files in fpdfsdk/ directory.
This is part of the efforts to make PDFium code compilable
by Clang chromium style plugins.
The changes are mainly the following:
-- move inline constructor/destructor of complex class/struct out-of-line;
-- add constructor/destructor of complex class/struct if not
explicitly defined;
-- add explicit out-of-line copy constructor when needed;
-- move inline virtual functions out-of-line;
-- Properly mark virtual functions with 'override';
-- some minor cleanups plus removing an unused file and splitting
cxfa_eventparam out from fxfa.h

The progressive decoder will attempt to verify that the provided image type
matches the actual image content. We need to disable this check when running
the fuzzer in order to target the fuzzing to specific decoders otherwise
each fuzzer will end up fuzzing all of the decoders.

The code has local variables that shadow struct or class member
variables. Also, when this happens, different variable names should be
used instead of namespaces.
These were discovered by /Wshadow warning flag in Clang.

redundant condition, and using bool in arithmetic operations.
Also remove a chunk of unused code.

Replace it with two generic slots for Links and Codec usage.
Since the codec is at a lower layer than the document, we
don't provide separate get/set methods, since having a
document upon which to call these would be a layering
violation. Do the same for the Links for simplicity.

Its only used to store one object, so replace it with a unique_ptr
to a class with a virtual dtor. Rename the prototypical class with
virtual dtor from CFX_DestructObject to CFX_Deletable. Rename the
fx_basic_module.cpp to cfx_modulemgr.cpp to match the one class
in it.

There were two defines, BBS_ and PBS_ for the various border styles in the
system. They were the same, except PBS_ had an extra SHADOW define which was
never used.
This CL combines both of those into a single BorderStyle enum class and updates
the code as needed.
Also, removes ADDBIT, GETBIT unused defines. Updates barcode code to use
the util.h defines instead of redefinition. fsdk_baseannot names starting with _ were cleaned up and some #defines moved to constants.

Add missing helper function to CFX_ByteTextBuf to avoid the
anti-pattern CFX_ByteString(sBuf.AsStringC()), using the name
"Make" to indicate there's an allocation going on in this case.

possible.

There are currently three ways to assert in the code (ASSERT, FXSYS_assert and
assert). This CL standardizes on ASSERT. The benefit of ASSERT is that it can
be overridden if the platform requies and we can pickup the Chromium version
if it has already been defined in the build.
This does change behaviour. Currently FXSYS_assert is always defined but ASSERT
is only defined in debug builds. So, the FXSYS_assert's would fire in Release
builds. That will no longer happen.

The few places these are called are better served by explicit
calls to CFX_ByteString() itself. This helps make Byte and
Wide strings more similar.
Also prevents fx_string.h from having any knowledge of fx_basic.h's
ByteTextBuf class.
