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.

resource: store 'end' instead of 'size' in struct resource ...

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.

fs: limit flash erase and protect to the partiton boundary ...

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.

lseek: return -1 instead of -errno ...

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.

    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.

Add automount support ...

This patch adds an automount command which makes it possible
to execute a script when a certain directory is first accessed.
It's the commands responsibility to make this directory available
(bringing devices up and mounting it). This results in automount
support which makes sure that from the shell every file can
be accessed without having to care for device bringup. Bringing
up devices may be expensive (USB, dhcp). The automount support
makes it easy for the environment to bringup devices when they
are actually needed.

fs: drop struct mtab_entry ...

every struct fs_device_d contains a struct mtab_entry, so they
have a 1:1 relationship. Instead of having to use container_of
to get from a struct mtab_entry to a struct fs_device_d we can
better embed the members of struct mtab_entry into struct fs_device_d
directly.
