7d06db201f Enhance printf() 
1. Add precision to limit string length.
   ccprintf("%.4s", "foobar") prints "foob"

2. Handle '*' for length, precision fields.
   ccprintf("%.*s", 3, "foobar") prints "foo"

3. Add hex-dump code "%h"
   ccprintf("%.*s", 4, "foobar") prints 666f6f62

BUG=none
TEST=at ec console, 'hash' prints the current hash

Also add snprintf(), and %X format code.
