This avoids a lot of duplicate code/ifdefs everywhere.

In the case of errors depending on network input (i.e. not programming
logic errors), we should report errors but not abort the application.
Assertions should be used to validate and document programmer
assumptions. Moreover, if assertions are deactivated at build-time, we
don't want our application to crash.

99 % of these are just whitespace changes. Some unnecessary includes
removed as well
