Clean up comment formatting. *Touches ~1/2 of sdk*

We had multiple oocdoc comment formats before. Some of those are following:

/**
 * Blah
 * Blah
 */

/** Blah
    Blah
 */

/**
    Blah
    Blah
 */

/**
    Blah
    Blah
*/

/** Blah */

...among others.

All should now be one of the following:

/**
 * Blah
 * Blah
 */

/** Blah */

The same also applies for non-oocdoc comments: just change /** to /* for
those.
