This is done to account for platforms, for which we want custom behavior upon the program termination, hence we call `mbedtls_exit()` instead of returning from `main()`. For the sake of consistency, introduces the modifications have been made to the test and utility examples as well. These, while less likely to be used in the low level environments, won't suffer from such a change.
