fs: ubootvarfs: use correct format specifier for pointer diff ...

The difference between two pointers is represented as a ptrdiff_t, use the
correct format specifier when printing to get rid of the following warning
in a 64bit build:

warning: format '%x' expects argument of type 'unsigned int',
but argument 3 has type 'long int' [-Wformat=]

OF: gpio: don't warn if ignored GPIO flag matches the behavior ...

Port of the upstream accepted change to the Linux kernel.

Some devicetrees specify the ACTIVE_LOW flag in the fixed regulator GPIO
handle. While this has always been ignored, it's consistent with the
behavior of the regulator binding in the absence of the
"enable-active-high" DT property. It doesn't make much sense to print a
user visible warning for a configuration which is consistent, so only
print the warning if the GPIO flag contradicts the behavior dictated by
by the enable-active-high property.

fs: devfs-core: do a case-insensitive compare of partuuids ...

partuuids are represented as hexadecimal strings, where case doesn't
matter. barebox formats them as lower case internally, forcing the
partuuid device tree property to be lower case too. Use strcasecmp to
be case-insensitive.

hwrng: dev-random: always use /dev/urandom ...

/dev/random can block long after boot time. It seems there's a consensus
that /dev/urandom is safe to use except for very early boot, which isn't
when barebox sandbox is usually run. To make the HWRNG more useful,
always use /dev/urandom.

edit: add vi alias with vi-style bindings ...

The edit command already supports a few key bindings for code
navigation. To improve user experience for vi-impaired users, add a vi
alias that maps traditional vi key bindings to the barebox edit ones.
This is done by adding a mode-aware read_modal_key that maps vi
normal-mode keys to barebox edit. For operations that requires more
than one barebox edit key, a backlog of two characters is additionally
used.

In interest of code size reduction, a command mode (and the associated
readline overhead) are not implemented, the effect of the most common
commands :q and :wq commands can be realized with vim-like ZQ and ZZ
bindings instead.

This increases the size of my LZO-compressed THUMB2 barebox by 843 bytes.
