util: replaced ENODATA with ENOATTR for non-Linux systems
...
On Linux ENODATA is defined but on BSD, and MacOSX ENOATTR is used
instead. Defined ENODATA to be ENOATTR when the system is not Linux.
v2: Replaced ENODATA and ENOATTR with -EFAULT that is exists everywhere
and added a comment (Ian Romanick)

util: Change os_same_file_description return type from bool to int
...
This allows communicating that it wasn't possible to determine whether
the two file descriptors reference the same file description. When
that's the case, log a warning in the amdgpu winsys.
In turn, remove the corresponding debugging output from the fallback
os_same_file_description implementation. It depends on the caller if
false negatives are problematic or not.

util/os_file: always use the 'grow' mechanism
...
Use fstat() only to pre-allocate a big enough buffer.
This fixes a race where if the file grows between fstat() and read()
we would be missing the end of the file, and if the file slims down
read() would just fail.
