Now that descriptions of error codes no longer have to be on the same line for the sake of generate_errors.pl, move them to their own line before the definition. This aligns them with what we do for other definitions, and means that we no longer need to have very long lines containing both the C definition and the comment. ``` perl -i -pe 's~^(#define +MBEDTLS_ERR_\w+ +-\w+) */\*[*!]<(.*)\*/~/**$2*/\n$1~' include/mbedtls/*.h ``` This commit does not change the output of generate_errors.pl.
