2018-06-22Avoid some duplicate const/non-const getters.Tom Sepez
Getters should nearly always be const when they return a non-const pointer to an unowned object. Saves a bit of code along the way. Grep for similar occurrences and add "const".

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().

This landed earlier as part of a larger change that got reverted for unrelated reasons. Now re-land it by itself. See https://pdfium-review.googlesource.com/c/pdfium/+/33370 If we don't have a document, then we can't dynamically tell if it is an XFA doc, so there's no reason to believe it should have all permissions. If there is an XFA doc under the covers, then the extension will give us the value.
