util: hex and octal number support for MemoryMap

Browse Source 
The import-trace tool supports a memorymap file as argument. Currently the
import tool accepts only decimal values, but the hexadecimal system is more
common to specify a memory address or range. To avoid a manual translation
between hex and dec values the patch extends the import tool to handle both
types according to the prefix of a value.
