cramfs does not compile since we updated zlib to the kernel
version. Fix this by using the kernel version of uncompress.c

dlmalloc seems to work more efficient with this chunk size.
Copying a bigger file (3MB) takes 271ms vs. 125ms on a i.MX27
board. Even bigger chunk sizes do not further improve performance.

fat_stat in fs/fat.c declares finfo but doesn't initialize it.
When get_fileinfo is called, fno->lfname and fno->lfsize are
tested but haven't been zeroed...This can lead to a wrong
behavior.

Mount without argument always print a "none" as device name mounted
because entry->parent_device is always NULL.
The problem is the mount function in fs/fs.c. parent_device is
initialized to NULL and never updated. With this patch,
parent_device is set with the mounted device name.
Moreover, the mount function has been modified to print the device
name plus device id using the dev_name function.

For disk like devices attached to MCI, ATA or USB it depends on the order they
will be recognized. So an unique number for all disk like devices is required.

fs: fix path_check_prereq()
This patch makes impossible the situations than path_check_prereq() can make
'return 0' without changing errno.

path_check_prereq is supposed to return 0 when a file does
not exist and S_UB_DOES_NOT_EXIST is given. stat() changes
errno, so we have to set errno back to 0 before returning.

chdir() allocates memory using mormalise_path(). But if path_check_prereq()
returns error than memory isn't freed.

does not exaclty match barebox coding style, but works nicely and
should be ready to give it a try.

the driver did not accept the device. Also, do not forget to
free the backingstore string.

This makes it possible to compile without devfs. devfs_create/devfs_remove
is used by drivers and thus must still be present even without devfs support.
Also, this patch adds cdev_open/cdev_close/cdev_flush/cdev_ioctl calls to
work with devices without using the file api.
