/** @file
* All actions handling saving and loading of the settings/configuration goes on in this file.
* The file consists of four parts:
* <ol>
* <li>Parsing the configuration file (openttd.cfg). This is achieved with the ini_ functions which
* handle various types, such as normal 'key = value' pairs, lists and value combinations of
* lists, strings, integers, 'bit'-masks and element selections.
* <li>Defining the data structures that go into the configuration. These include for example
* the _patches struct, but also network-settings, banlists, newgrf, etc. There are a lot
* of helper macros available for the various types, and also saving/loading of these settings
* in a savegame is handled inside these structures.
* <li>Handle reading and writing to the setting-structures from inside the game either from
* the console for example or through the gui with CMD_ functions.
* <li>Handle saving/loading of the PATS chunk inside the savegame.
* </ol>
* @see SettingDesc
* @see SaveLoad

/** 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 patches 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 patches there (in
* place) and you DON'T have to increase the savegame version. */
