- added xmlRemoveID() and xmlRemoveRef()

- added check and handling when possibly removing an ID
- fixed some entities problems
- added xmlParseTryOrFinish()
- changed the way struct aredeclared to allow gtk-doc to expose those
- closed #4960
- fixes to libs detection from Albert Chin-A-Young
- preparing 1.8.3 release
