haiku/headers/posix/sys/stat.h
Ingo Weinhold bcfe344c53 * Made our struct stat POSIX compliant again -- the time_t fields have been
replaced by timespec fields. Via macros the structure is still source
  compatible with the old one.
* Introduced header <compat/sys/stat.h> that defines the old stat structure
  (as stat_beos) and conversion functions
* Introduced versions for [l,f]stat().
* Added symbol versions for BDirectory::GetStatFor() for sake of binary
  compatibility.
* BStatable::GetStat(): Renamed the old method, changed its parameter to
  stat_beos*, and and made it private. Added a new version (using up a
  reserved vtable slot). It remains source and binary compatible.
* BRefFilter::Filter(): Changed the struct stat* parameter to struct stat_beos*
  for sake of binary compatibility. This breaks source compatibility, though,
  which we can't help, since the class doesn't have reserved vtable slots.
* Fixed several issues with the stat structure change, mostly adjusted uses of
  BRefFilter.
