The standard devices are currently broken since they have
the size ~0. As now files use loff_t as file size which is a signed
type the read implementation gets confused and now returns -1.
The current implementation also has the (somewhat theorical) problem
that we do not have real streaming devices, so /dev/zero went out
of zeroes after reading 4GB (or now LLONG_MAX).
This patch introduces a new cdev flag DEVFS_IS_CHARACTER_DEV and a new
file size flag FILE_SIZE_STREAM which makes it possible to create
real stream devices instead.

Storing the size instead of the resource end in struct resource was
a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously
leads to problems. 'end' on the other hand will never exceed
UINT[32|64]_MAX. Also this way we can express a iomem region covering
the whole address space.

When creating a file or a directory we have to check if the parent
is actually a directory. Otherwise trying it results in a crash.

In the Kernel the mtd ioctls expect a pointer to the offset, whereas
barebox interprets the pointer itself as an offset. Since we want
to add 64bit support for file sizes a pointer may not be sufficient,
so align with the kernel and convert it to a pointer to the offset.

With files smaller than the tftp block size the whole transfer is done
in tftp_do_open already. In this case we are in STATE_DONE, but there
is no error. Set priv->err to 0 and check for it to be able to transfer
small files.

Passing a too large size or offset to erase could
affect flash outside the partition boundary.
Addresses for SPI flash wrap around, thus giving a
count + offset going past the end of the flash would
wrap around and erase flash at offset 0.
Add the same check for protect.

The patch making errno a positive value has another bug:
lseek was switched to return -errno instead of -1. This does not
work since we can lseek we can address the whole 4G address space,
have of which has a negative offset when interpreted as a signed
integer. Let lseek return -1 on failure again instead.

Writing big files takes longer and longer because of the chunk list
By storing a pointer of the recent used chunk in the inode, access times are
improved.
Testet on with tftp 10M:
OMAP4 chunk size 4096: 12244ms 8192: 4239ms
patched 2647ms 2785ms
i.MX35 chunk size 8192: 7225ms
patched 2691ms
No impact on much smaller files seen

Make errno a positive value
Normally errno contains a positive error value. A certain unnamed developer
mixed this up while implementing U-Boot-v2. Also, normally errno is never
set to zero by any library function.
This patch fixes this.
