[issue10142] Support for SEEK_HOLE/SEEK_DATA

[Jesús Cea Avión]

Jesús Cea Avión <jcea at jcea.es> added the comment:

This is far more complicated that expected, because I would like to modify "file.seek()" to be able to support these flags too. Analizing "Modules/_io/bufferedio.c:buffered_seek()", the logic is pretty convoluted and the ramifications are extensible.

Should I limit myself to "os.lseek()"/"os.read()"/"os.write()"?. This flags are obscure, but useful enough to be useful even with this limitation.

Fut I don't feel comfy with this partial support.
