uimage/file_to_sdram: fix resource allocation ...

file_to_sdram is used to load an initrd. The resource size is
then used to pass the initrd size to Linux. This means that
the resource size must exactly match the initrd size. Currently
this is not the case since we request the sdram region in chunks
of 8 Kbytes. Fix this by adjusting the resource size when the file
is loaded.

hush: bail out of scripts on syntax error ...

On a systax error we have to bail out of the shell instead of
setting inp->p to NULL and crash barebox with a NULL pointer
deref. This only happened in scripts.

This fixes the problem I had (i.e. a boot loop caused by a stray fi in
/env/bin/init).

hush source: expand $PATH ...

The behaviour of other shells suggest that with source or '.'
the path should be resolved using the PATH environment variable. Do

ARM: Allow to compile in thumb-2 mode ...

This shrinks the resulting binary size by ~25%. Exceptions
are still handled in arm mode, so we have to explicitely
put .arm directives into the exception code. Thumb-2 mode
has been tested on i.MX51 Babbage board.

command: do not allow abbreviated commands anymore ...

abbreviated commands are derived from U-Boot and are only
partly useful. Noone expects from a shell to support this,
also we have tab completion. They also have some funny
side effects. For example we have a 'time' command. If this
command is not compiled in, the time command is interpreted
as an abbreviated version of the 'timeout' command. So remove
support for abbreviated commands and safe the binary space.

getopt: save and restore context ...

execute_command is the single point where commands are executed and thus a new
getopt context is needed. currently we call getopt_reset here to reset the
context. This breaks though when a command tries to run a command itself by
calling execute_command or run_command.  In this case we have to store the
context and restore it afterwards. The same is necessary in builtin_getopt.
Currently noone does this so this one shouldn't fix a bug, but merely allows
us to do such things later.

block: reimplement caching ...

The current caching layer only has a single buffer for
writing and reading. The FAT driver often accesses the
fat and then data again, which currently can't be cached.
Reimplement this with a list of cached chunks. The number
of chunks and their sizes are currently hardcoded, but
that could be easily made configurable.
