Add int return values to MD5 function calls

Browse Source 
The following function calls are being deprecated to introduce int
return values.
    * mbedtls_md5()
    * mbedtls_md5_starts()
    * mbedtls_md5_update()
    * mbedtls_md5_finish()
    * mbedtls_md5_process()
The return codes can be used to return error values. This is important
when using hardware accelerators.
