2018-08-17Rename CJS_Return to CJS_Result.Tom Sepez
"Return" is a verb, and "return" is a reserved-word at that, so avoid using it as part of a class name. Fully mechanical change apart from rename.

2018-08-17Introduce safer CJS_Return::Success() and Failure().Tom Sepez
Avoid the possibility of ever re-introducing the issue noticed last week. Remove some redundant JSGetStringFromID() calls.

2018-07-16Alert embedder when attempting to save XFA formRyan Harrison
This CL adds an experimental callback to the form fill API that allows PDFium to signal to the embedder that an attempt call save occurred. The embedder is responsible for showing an appropriate UI when this occurs. When PDF saving is implemented the API can be removed.

2018-06-21Clean up constant values for JS alert and beepRyan Harrison
Define constant values in the public API for the valid values of alert button type, alert icon type, and beep type. Replace various magic numbers through out the code base using these values. Also replace the XFA specific versions with an enum class that is guaranteed to have the same values, instead of #defines that just happen to. This CL does not attempt to add error checking on these values, since it currently doesn't exist so adding it may cause regressions.

2018-06-20Re-work some more c_str() usage.Tom Sepez
Many of these are converting ByteString => c_str => ByteStringView, since the ByteStringView ctor is implicit. This is unfortunate, since that involves a strlen() which the ByteString already knows if we use AsStringView() instead. This changed one test result where we can now return the string "\0" instead of "" -- since strlen no longer eats the NUL. This seems consistent, say, with String.fromCharCode().

Precursor to removing some more v8::Context slot dependency. There's a cost to maintaining the set of observers, but since these objects are tied to V8 lifetimes, not C++ lifetimes, we want to be very wary of the document going away unexpectedly.
