* Moved the global BPrivate::WidthBuffer from BTextView into BPrivate as

gWidthBuffer.
* Tracker PoseView now uses BPrivate::gWidthBuffer instead of it's own
  instance.
* TextView.h and PoseView.h are now a little cleaner.
* InterfaceDefs.cpp now deletes gWidthBuffer in _fini_interface_kit_().
* Added binary compatibility support for NetPositive in WidthBuffer.h and .cpp.
  Obviously it kind of defeats the purpose of having WidthBuffer neatly tucked
  away in the BPrivate namespace, but Haiku should run NetPositive, I guess.
  Fixes #2879.
