[SLOF] [PATCH 0/2] Improve stack usage in libnvram

[Thomas Huth]

Here's the rework of the patch that improves stack usage in libnvram.
I've split it in two parts now:
First patch reworks the functions from envvar.c. These functions do
not really rely on the NUL-terminated strings, so I've changed them
now to deal with the Forth strings directly instead - no more
temporary buffers needed here!
The second patch contains the fix for get_partition. Here I kept the
separate wrapper function get_partition_fs() with the temporary buffer,
since this was the easier and more readable way to fix this issue there
(get_partition() is used all over the place, so the patch would also
get much bigger otherwise).
