Subject: lib: uuid: add functions to generate UUID version 4
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.
