This will allow to execute any file and detect it's type to handle it.
This will allow to use shell for bootp bootfile or dfu.
You can register multiple hook for the same filetype. They will be execute
in the invert order of register. If a hook does not handle the file you just
return -ERESTARTNOHAND;
This is only available with hush parser.

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

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.

Positional parameters are not nice, so implement a getopt
function. This has to be done as a builtin because otherwise
we have no access to the parents argc/argv.
getopt works as expected, here is a little example:
while getopt "hs:" OPT
do
if [ $OPT = h ]; then
echo "usage"
exit 1
else
echo "scr: opt: $OPT optarg: $OPTARG"
fi
done

Fix memory leak in globbing part of hush. a simple '['
on the command line was enough to trigger it.
We must call globfree() before setting the glob structure
to zero.

v2: Do not exit from all scripts but only the current one
This fixes the case:
barebox:/ cat /test
if [ 0 = 0 ]; then
exit 1
fi
barebox:/ /test
barebox:/ echo $?
0
barebox:/
Also, remove code to not allow exit from main shell. The for(;;) loop
in common/startup.c will bring us back anyway.

No need to check for maximum argument counts. The commands are
safe to be called with more arguments, so lets safe some bytes.

This patch removes adding of an additional \ when doing
echo "\""
which gives \" instead of just "
I checked in latest busybox hush and this code is still present there,
but it behaves correctly in busybox due to some other code pathes I
didn't investigate.
If this change has any unwanted side effects feel free to flame on me

For practical reasons I changed all string literals assumed to be constant
to reside in .rodata subsection at end of .text section.
