mem md: make md -s /dev/something work again ...

|commit d22b85a
|Author: Sascha Hauer <s.hauer@pengutronix.de>
|Date:   Wed Jul 4 23:41:13 2012 +0200
|
|    mem md: bail out without arguments
|
|    Without arguments the 'md' command defaults to show address 0 which
|    likely results in a NULL pointer exception, so only three keystrokes
|    are necessary to crash barebox. Show usage instead if 'md' is invoked
|    without arguments, so that it at least requires an address to be given
|    to crash barebox. This increases the stability of barebox by 66%. Hurray!

barebox does not crash any longer when a plain 'md' without additional arguments
is exectuted. However, doing a 'md -s /dev/nor0' was a standard usecase which now
does not work anymore.

commands/crc: assert newline after output with big offsets ...

This fixes

	barebox@Very long board name:/ crc32 -f /dev/mem 0x83f00000+0xfff
	CRC32 for /dev/mem 0x83fff000 ... 0x83fffffe ==> 0xa080584bbarebox@Very long board name:/

The problem here was that the return value of
lseek(fd, 0x83f00000, SEEK_SET) (which is 0x83f00000) was casted to an
int (which is -2081423360), returned to do_crc and interpreted as
error there without yielding another error message.

This also makes

	crc32 -f /dev/mem 0xffffffff+0x1

die on a NULL pointer exception instead of reporting:

	lseek: No error

mtd: fix bad block ioctls ...

Since this commit we interpret the argument to the bad block ioctls
as a pointer to a 64bit number:

|commit e71c343

|Date:   Fri Oct 14 11:57:55 2011 +0200
|
|    mtd: fix arguments to bad block ioctls
|
|    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.

fs: fix standard zero, full devices ...

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.
