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.

By doing so glob will not return GLOB_NOMATCH anymore but instead

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 ".

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.

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.
