/****************************
 * OTTD specific INI stuff

/**
 * Settings-macro usage:
 * The list might look daunting at first, but is in general easy to understand.
 * We have two types of list:
 * 1. SDTG_something
 * 2. SDT_something
 * The 'G' stands for global, so this is the one you will use for a
 * SettingDescGlobVarList section meaning global variables. The other uses a
 * Base/Offset and runtime variable selection mechanism, known from the saveload
 * convention (it also has global so it should not be hard).
 * Of each type there are again two versions, the normal one and one prefixed
 * with 'COND'.
 * COND means that the setting is only valid in certain savegame versions
 * (since settings are saved to the savegame, this bookkeeping is necessary.
 * Now there are a lot of types. Easy ones are:
 * - VAR:  any number type, 'type' field specifies what number. eg int8 or uint32
 * - BOOL: a boolean number type
 * - STR:  a string or character. 'type' field specifies what string. Normal, string, or quoted
 * A bit more difficult to use are MMANY (meaning ManyOfMany) and OMANY (OneOfMany)
 * These are actually normal numbers, only bitmasked. In MMANY several bits can
 * be set, in the other only one.
 * The most complex type is INTLIST. This is basically an array of numbers. If
 * the intlist is only valid in certain savegame versions because for example
 * it has grown in size its length cannot be automatically be calculated so
 * use SDT(G)_CONDLISTO() meaning Old.
 * If nothing fits you, you can use the GENERAL macros, but it exposes the
 * internal structure somewhat so it needs a little looking. There are _NULL()
 * macros as well, these fill up space so you can add more settings there (in
 * place) and you DON'T have to increase the savegame version.
 *
 * While reading values from openttd.cfg, some values may not be converted
 * properly, for any kind of reasons.  In order to allow a process of self-cleaning
 * mechanism, a callback procedure is made available.  You will have to supply the function, which
 * will work on a string, one function per setting. And of course, enable the callback param
 * on the appropriate macro.
