Move the directory iterator test to libsquashfs, move the tree
scanning code to libcommon.

On platforms like Windows, we don't have fnmatch.h and a libcompat
implementation is provided. Instead of including fnmatch.h, include
compat.h which includes the propper headers, if available.

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

When dropping the parent iterator, update the state _first_.

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.

Since the user has to call istream_get_buffered_data afterwards anyway,
we can do the precache lazily.

This properly maps to all of our use cases and makes istream_precache
obsolete.

As soon as we no longer have any data to read, unlock/drop the
parent iterator_t object. Also, make sure we get the buffer
count right, not all data might have been consumed yet when
precache is called. Remove the precache/read loop in the non-sparse
case, we have already established that there is data available. If
it is insufficient, the user will simply call precache again once
it's used up, which istream_get_buffered_data forwards to a precache
call in the underlying stream.

Instead, go through helper functions, which in a next step can be
moved inside the implementation.

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.

Instead, make the buffer const, let the user adjust the pointer and
size. The offset can then be inferred in precache.

The end goal is to remove direct buffer access from the istream_t
interfaces and make that opaque. For the tar implementation, this
already safes us needless buffer copying, as we essentially allow
the user to read-through from the underlying stream.

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.
