Move MBEDTLS_ERR_xxx Doxygen comments before the definition
...
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.

More flexible parsing of Doxygen comments for MBEDTLS_ERR_xxx
...
Before this commit, definitions of error codes must match a strict pattern,
with a Doxygen comment following the definition on the same line and
starting with "/**<". Change how generate_errors.pl so that the Doxygen
comment can be before the definition instead of after, and doesn't have to
be on the same line.
Also allow spaces between "#" and "define", and allow Doxygen comments to
start with "/*!" rather than "/**". Starting with "///" or "//!" is not
supported.
This commit does not change the output of generate_errors.pl.
