This patch adds support to generate UUID (Universally Unique Identifier) in version 4 based on RFC4122, which is randomly.

Source: https://www.ietf.org/rfc/rfc4122.txt

Changes:

• new configs:
  • CONFIG_LIB_UUID for compile lib/uuid.c
  • CONFIG_RANDOM_UUID for functions gen_rand_uuid() and gen_rand_uuid_str()
• add configs dependency to include/config_fallbacks.h for lib uuid.

lib/uuid.c:

• add gen_rand_uuid() - this function writes 16 bytes len binary representation of UUID v4 to the memory at given address.

• add gen_rand_uuid_str() - this function writes 37 bytes len hexadecimal ASCII string representation of UUID v4 to the memory at given address.
