/**
* @file
* This file contains metaserver2 information - the metaserver2

/*
* The current implementation of crossfire is not very thread
* friendly/safe - in fact, metaserver2 is the first part to
* use an extra thread.
* As such, it would be a lot of work to add the necessary
* locks in the rest of the code for the metaserver2 to be able
* to get the data it needs. So instead, we use this
* MS2UpdateInfo structure to get the data from the main thread
* to the metaserver thread - basically, the main thread
* gets a lock on the mutex, updates the fields in this structure
* and releases the lock. The metaserver2 thread will
* get a lock when it needs to get this information, copy
* it to the post form, then unlock the structure.
* In that way, neither side holds the lock very long, which is especially
* important because the metaserver2 thread could take quite a while
* to do its updates.
