scripts: add STATE logging level for state save/restore output.

The save/restore state output is voluminous; using this flag allows us
to quickly see or ignore when something is just being saved.

[Yann E. MORIN: this is a blind log level, and is used only to search
in the build-log afterward.]

    11 On sh[34]-linux, memset function does not work if 2nd argument is negative
    12 and 3rd argument is greater than 12.
    13 for example, memset(ptr, "\xda", 20) sets 0xff instead of 0xda.
    14  
    15 Attached patch fixes this problem.
