Trim trailing whitespace. It doesn't match OpenSSL coding standards,
AFAICT, and it can cause problems with git tooling.
Trailing whitespace remains in test data and external source.

We have a number of instances where there are multiple "init" functions for
a single CRYPTO_ONCE variable, e.g. to load config automatically or to not
load config automatically. Unfortunately the RUN_ONCE mechanism was not
correctly giving the right return value where an alternative init function
was being used.

RUN_ONCE really just returns 0 on failure or whatever the init
function returned. By convention, however, the init function must
return 0 on failure and 1 on success. This needed to be clarified.

Because pthread_once() takes a function taking no argument and
returning nothing, and we want to be able to check if they're
successful, we define a few internal macros to get around the issue.
