The problem was, that the CPDF_SyntaxParser read last block
not from requested position. In this case It move down
requested position to fill whole buffer. As result this additional
data was not requested by DownloadHints.
To fix this allow resize data buffer in CPDF_SyntaxParser, to store
more small block, and always read from requsted position.
Also add reading check into CPDF_Parser::LoadLinearizedMainXRefTable to
prevent infinite loops.

This ports
https://chromium-review.googlesource.com/c/chromium/src/+/599127 from
Chromium to PDFium.
Because VC++ does not have format-string checking for user-defined
functions during normal compiles, because clang-cl had its format-string
checking disabled, because some files are only compiled on Windows, and
because VC++'s /analyze doesn't build all targets, and because VC++'s
format-string checking is more lenient than clang's... 50 warnings about
format-string mismatches crept in to Chromium's build. Seven of these
were somewhat serious, with four being wchar_t*/char* mismatches because
of base::FilePath and the other three being size_t/%d mismatches.
Now that all of the mismatches are corrected this change enables
PRINTF_FORMAT checking with clang-cl so that these bugs never return.

Previous implementation assumed that if the local colour palette was
not specified and the global palette had its size specified, then use
the global. If the global palette is disable, it will not have data,
but it may have a size. Technically the size is giberish in this case,
but the value is allowed to be non-zero, so isn't a sufficient check.

Wrt the creation pattern, there is no longer a constructor and 2

initialization is done as part of the constructor. A wrapper has been
added for generating a std::unique_ptr<CFX_LZWDecoder>, so that params
