* Unify location handling of error functions.Gravatar Emilio Jesus Gallego Arias2016-08-19
| | | | | | | | | | | | | | In some cases prior to this patch, there were two cases for the same error function, one taking a location, the other not. We unify them by using an option parameter, in the line with recent changes in warnings and feedback. This implies a bit of clean up in some places, but more importantly, is the preparation for subsequent patches making `Loc.location` opaque, change that could be use to improve modularity and allow a more functional implementation strategy --- for example --- of the beautifier.

This allows to remove a lot of independent code from Evd which was put into the UState module. The API is not perfect yet, but this is a first pass. Names of data structures should be thought about too because they are way too similar.
