2017-11-29[CFI] Enable type generalization for LCMSVlad Tsyrklevich
Control Flow Integrity [1] indirect call checking verifies that function pointers only call valid functions with a matching type signature. This condition can be too strict, a common form of 'abstraction' relies on function pointers being cast to generalize argument pointer types to void*. In LCMS these failures occur because of casts of function pointers called as both _cmsInterpFn16 (cmsInterpFunction.Lerp16) and _cmsOPTeval16Fn (as an argument to _cmsPipelineSetOptimizationParameters) types making it difficult to refactor out easily. Instead, enabling the type generalization build config weakens the type checking performed for CFI-icall to accomodate this common type of casts.

2017-11-28Convert from character stream to visible text indices in GetTextRyan Harrison
Most of the API methods FPDFText operate on indices in terms of the underlying stream of characters. This stream includes non-printing control characters, which are not part of the visible text. The majority of files do not appear to have these hidden characters so there is a 1:1 correspondence between them. When they are present conversion needs to occur to make sure that GetText doesn't attempt to retrieve for a span that is out of range.
