new commands: uuid and guid - generate random unique identifier
Those commands basis on implementation of random UUID generator version 4
which is described in RFC4122. The same algorithm is used for generation
both ids but string representation is different as below.
char: 0 9 14 19 24 36
xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
UUID: be be be be be
GUID: le le le be be
Commands usage:
- uuid [<varname>]
- guid [<varname>]
The result is saved in environment as a "varname" variable if argument is given,
if not then it is printed.
New config:
- CONFIG_CMD_UUID
