/**
 * Settings-macro usage:
 * The list might look daunting at first, but is in general easy to understand.
 * The macros can be grouped depending on where the config variable is
 * stored:
 * 1. SDTG_something
 *    These are for global variables. Here 'var' refers to a global variable.
 * 2. SDTC_something
 *    These are for client-only variables. Here the 'var' refers to an
 *    entry inside _settings_client.
 * 3. SDT_something
 *    These are for members in the struct described by the current
 *    #SettingDesc list / .ini file.  Here, 'base' specifies type of the
 *    struct while 'var' points out the member of the struct (the actual
 *    struct to store it in is implicitly defined by the #SettingDesc
 *    list / .ini file preamble the entry is in).
 *
 * The something part defines the type of variable to store. There are a
 * lot of types. Easy ones are:
 * - VAR:  any number type, 'type' field specifies what number. eg int8_t 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.
 * If nothing fits you, you can use the GENERAL macros, but it exposes the
 * internal structure somewhat so it needs a little looking.
 *
 * 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.
