Orignally proposed by Sam Revitch <sam.revitch@gmail.com>.
Unregister device files at disconnection to avoid the futher accesses.
Also, the dev_unregister callback is removed and replaced with the
combination of disconnect + free.
A new function snd_card_free_when_closed() is introduced, which is
used in USB disconnect callback.

Modules: RTC timer driver,Timer Midlevel
Add a module pointer to the timer structure and use it for refcounting
instead of the card's module pointer to prevent the global timer
modules (rtctimer and hpetimer) from being removed while in use.

This patch contains the following possible cleanups:
- make needlessly global code static
- #if 0 the following unused global functions
- remove the following unneeded EXPORT_SYMBOL's

Removal and replacement of magic memory allocators and casts (core part)
This patch replaces snd_magic_kmalloc(), snd_magic_kcallc() and snd_magic_kfree()
with kmalloc(), kcalloc() and kfree(), respectively.
The cast via snd_magic_cast() is replaced with the standard cast, too.
