Changes: - move uuid<->string conversion functions into lib/uuid.c so they can be used by code outside part_efi.c. - rename uuid_string() to uuid_bin_to_str() for consistency with existing uuid_str_to_bin() - add an error return code to uuid_str_to_bin() - update existing code to the new library functions.

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.
