docs: some coding style updates

Primarily:

1. Mention that we prefer if return parameters carry "ret_" as prefix in
   their name

2. Clarify that debug-level logging is always OK, and irrelevant to when
   deciding whether a function is logging or non-logging.

+- Typically, function parameters fit into three categories: input parameters,

 ## Logging
 
 - For every function you add, think about whether it is a "logging" function or
-  a "non-logging" function. "Logging" functions do logging on their own,
-  "non-logging" function never log on their own and expect their callers to
-  log. All functions in "library" code, i.e. in `src/shared/` and suchlike must
-  be "non-logging". Every time a "logging" function calls a "non-logging"
