hush has a long standing and anoying glob bug. hush expands wildcards
during parsing of the script or command stream. When the command stream
begins to execute the wildcards are already expanded which leads to:
mkdir /tmp
cd /tmp
mkdir foo; ls *
ls: *: No such file or directory
To fix this expand wildcards right before executing the command. Since
'for' loops are not executed in commands, we have to keep the old behaviour
in here so that 'for i in *' still works.

hush used to escape '*' '[' '?' during parsing because the quotes
got removed in the first parsing loop.
globhack is used to remove these escapes again for glob. Since we now
keep the quotes until the end of parsing and we no longer escape glob
wildcards, we do no longer have to remove any quotes. With this globhack
can be much simpler.
While at it, change the prototype to match the one from glob() and rename
the function to fake_glob, because that's what it is: it just copies the
input string into the output struct without actually globbing.

hush removes the quotes from strings too early. This leads to some bugs.
When hush executes
echo "hello sascha"
it correctly results in:
argv[0] = "echo"
argv[1] = "hello sascha"
However, the following behaves incorrect:
a="hello sascha"
echo "$a"
results in:
argv[0] = "echo"
argv[1] = "hello"
argv[2] = "sascha"
This is because hush removes the quotes and inserts variable values in a
single loop, so
echo "$a"
becomes:
echo hello sascha
after the loop.
Instead, keep the quotes until all variables are inserted and remove them
at the end.
This also fixes that echo \" resulted in \" instead of ".

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.

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.

Barebox does not have interrupt functionality. Nevertheless it's
sometimes useful to periodically call functions, like for example
a heartbeat LED or watchdog reset. Instead of cluttering the code
with calls to these functions this patch adds a generic polling
infrastructure. Code which might run for longer now can call
poller_call() periodically which in turn will call all registered
pollers.
This patch adds a call to poller_call in two generic pathes. First
of them is getc() which covers waiting for uart input. Second is
ctrlc() which should be called anyway from code which might run
for longer. So instead adding poller_call directly to your code,
consider checking ctrlc instead which also gives additional
convenience to the user.
The poller code is safe against reentrancy which means that it's
safe to call poller_call inside a poller.

Clients now only have to call menu_add_submenu or menu_add_command_entry
instead of allocating many strings.
This also fixes some problems in the menu code. The priv field in struct
menu_entry was a pointer to struct menu or a pointer to an allocated string.
It was never freed, only had to be freed when it was an allocated string.
The reference to a submenu is now kept as a string and not to the menu
itself. The code checked the existence of the submenu when creating it, but
crashed when the submenu was removed and referenced afterwards. Now the
code hapily allows references to nonexistant menus but complains during
