Pavel Pisa 9394aa5ed7 untar: do not exit with error when created directory already exists.
The problem exists for both RTEMS untar implementations and their
variants: Untar_FromMemory(), Untar_FromFile() and rtems_tarfs_load().

If filesystem object already exists at extracted directory path
then if it is directory, creation is ignored. Attempt
to delete/unlink object and make directory is tried for other cases.

This simple approach problem reported in ticket fixes #2413.
Behavior follows GNU tar and BSD tar practice for directories
but much more work is required to achieve full semantics
of the full featured tar implementation still.

untar.c contains two procedures for extracting files from a UNIX
tar file:

    int Untar_FromMemory(unsigned char *tar_buf, unsigned long size);
    int Untar_FromFile(char *tar_name);

Untar_FromMemory(...) takes its input from a chunk of allocated memory.
This is particularly useful when the tar is stored in Flash memory or
comes from the FTP daemon by way of a hook.

Untar_FromFile(...) is identical except the source is from an existing
file.  The fully qualified filename is passed through char *tar_name.
