[PATCH 2/8] SPU add chdir/chmod/chown/mkdir/rmdir functions


Add the following functions, implmented via assist calls:

	int chdir(const char *path)
	int fchdir(int fd)
	int mkdir(const char *pathname, mode_t mode)
	int mknod(const char *pathname, mode_t mode, dev_t dev)
	int rmdir(const char *pathname)
	int chmod(const char *path, mode_t mode)
	int fchmod(int fildes, mode_t mode)
	int chown(const char *path, uid_t owner, gid_t group)
	int fchown(int fd, uid_t owner, gid_t group)
	int lchown(const char *path, uid_t owner, gid_t group)

newlib ChangeLog:

2007-06-18 Patrick Mansfield <patmans@us.ibm.com>

	* libc/include/sys/unistd.h: Make fchdir prototype visible.
	* libc/include/sys/stat.h: Make mknod and lstat prototypes visible
	for __SPU__ (lstat support is in a later patch).

libgloss ChangeLog:

2007-06-18 Patrick Mansfield <patmans@us.ibm.com>

	* spu/jsre.h: Add defines for new assist calls.
	* spu/chdir.c: New file, support chdir via assist call.
	* spu/chmod.c: New file, support chmod via assist call.
	* spu/chown.c: New file, support chown via assist call.
	* spu/fchdir.c: New file, support fchdir via assist call.
