    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.

    Changes in lib/uuid.c to:
    - uuid_str_to_bin()
    - uuid_bin_to_str()

    New parameter is added to specify input/output string format in listed functions
    This change allows easy recognize which UUID type is or should be stored in given
    string array. Binary data of UUID and GUID is always stored in big endian, only
    string representations are different as follows.

    String byte: 0 36
    String char: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
    string UUID: be be be be be
    string GUID: le le le be be

    This patch also updates functions calls and declarations in a whole code.
