Heinrich Schuchardt 7bae13da36 cli: avoid buffer overrun 
Invoking the sandbox with

    /u-boot -c ⧵0xef⧵0xbf⧵0xbd

results in a segmentation fault.

Function b_getch() retrieves a character from the input stream. This
character may be > 0x7f. If type char is signed, static_get() will
return a negative number and in parse_stream() we will use that
negative number as an index for array map[] resulting in a buffer
overflow.
