Dimitrie O. Paun 0415030f51 Lookup driver information in registry and system.ini. 
Make the code inspect the registry/system.ini at call time, rather
then initialization time.
Code cleanups.

/* TODO:
* - implement WINMM (32bit) multitasking and use it in all MCI drivers
* instead of the home grown one
* - 16bit mmTaskXXX functions are currently broken because the 16
* loader does not support binary command lines => provide Wine's
* own mmtask.tsk not using binary command line.
* - correctly handle the MCI_ALL_DEVICE_ID in functions.
* - finish mapping 16 <=> 32 of MCI structures and commands
* - implement auto-open feature (ie, when a string command is issued
* for a not yet opened device, MCI automatically opens it)
* - use a default registry setting to replace the [mci] section in
* configuration file (layout of info in registry should be compatible
* with all Windows' version - which use different layouts of course)
