src/config.c: Revamp configuration file parsing
Reintroduce a map for configuration variable parsing. We use a different
approach this time: Each map entry contains
* a key,
* a callback that can be used to parse that variable,
* a callback that can be used to serialize that variable and
* a target buffer that the parsed value is written to/read from.
Commits 4f4891bdb88410ae04225f3d6acfa31d73a3901a and
6377582841118688aee13aff98c9216403582e45 show that we are pretty
undecided on using a map or not. However, now that we use parser and
serialization wrappers for every variable, having a central map makes
everything much cleaner. The runtimes of config_load() and config_save()
are slightly increased (by a constant factor). This will also allow us
for implementing proper detection of missing configuration variables in
the configuration file.
