hush: Fix globbing ...

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: pass GLOB_NOCHECK to glob ...

By doing so glob will not return GLOB_NOMATCH anymore but instead
just does what fake_glob would do.

hush: simplify globhack ...

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: remove quotes at end of processing ...

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 ".

Makefile: fix build timestamps ...

This patch adds the scripts/mkcompile_h from the Kernel. This gives
us additional information about the build like who built this binary
and with which compiler. Currently the only information used is the
build timestamp and the generation number.
This also fixes the build timestamp in the banner which is now correct
even with consecutive builds without making clean in between.
