When testing trafgen with the following example from the man page the
error message "Failed to parse MAC address 11:22:33:44:55:66" is
printed.
trafgen -o lo --cpus 1 -n 3 '{ eth(da=11:22:33:44:55:66, da[0]=dinc()), tcp() }'
Turns out errno was not cleared before str2mac() called sscanf().

Returned string must be freed after use by the caller.

Break out all string handling functions and lockme stuff in order
to further eliminate the big code blob in xutils, so that it can
be easier maintained.
