Address doc comment rot in the standard library.

- Match @param/@tparam names to the actual parameter name
- Use @tparam for type parameters
- Whitespace is required between `*` and `@`
- Fix incorrect references to @define macros.
- Use of monospace `` and {{{}}} (much more needed)
- Remove `@param p1 ...` stubs, which appear in the generated docss.
  - But, retainsed `@param p1` stubs, assuming they will be filtered from
    the generated docs by SI-5795.
- Avoid use of the shorthand `@param   doc for the solitary param`
  (which works, but isn't recognized by the code inspection in IntelliJ
  I used to sweep through the problems)

The remaining warnings from `ant docs` seem spurious, I suspect they are
an unintended consequence of documenting extension methods.
