Using --exclude or -E it is now possible to exclude
files from the input tar stream.
The options can be used multiple times.

- The ostream creation functions already have flag arguments,
but make them an sqfs_u32 instead of int.
- Add flag arguments to the istream functions, sanitzie and forward
them when opening the handle.

Report an error number from the implementations, change the users to
forward that error number (which also means libtar write header/link
now returns an error code) and all subsequent binaries to use
sqfs_perror() instead of relying on the function to print an error
internally.
Also, make sure to preserve errno/GetLastError() in the implementations
and print out a stringified error in sqfs_perror() if the error code
indicates an I/O error.

For now, only the interfaces and helper functions are moved, the
concrete implementations remain in libio.

Instead of a separate append-sparse function, simply accept NULL
as an input for append. For both Unix and Win32, a fallback needs
to be implemented. For XFRM, we can just memset the input buffer
to zero, same for the libsquashfs data writer.

The structure and functions are renamed to sqfs_xattr_* instead,
an additional helper is added to accept an encoded xattr.
Documentation and unit test are added as well.

The existing istream_t wrapper is mered into this one as well, we
can open the files via the iterators open_file_ro function. Unit
tests and tar2sqfs are modified accordingly.

In the istream implementation, automatically skip the padding when we
reach end-of-file. Also skip file AND padding when we destroy the
object. Replace the remaining instances with a simple istream_skip
instead and remove the wrapper from libtar.

The tar_istream_t reads the data from a tar file, having been given
the header, and synthesizes zero bytes for sparse regions.
