The idea is to panic() when there is no memory available for normal
operation. Exception: code which can consume arbitrary amount of RAM
(example: files allocated in ramfs) must report error instead of panic().
This patch also fixes code which didn't check for NULL from malloc() etc.
Usage: malloc(), memalign() return NULL when out of RAM.
xmalloc(), xmemalign() always return non-NULL or panic().

The do_devinfo_subtree() function is only used if devinfo is compiled
in, so put it under the same ifdef. This avoids the following warning
when built with allnoconfig:
lib/driver.c:247: warning: 'do_devinfo_subtree' defined but not used

before if you specify id = 0 the next available id will be taken
otherwise fail if already registered now as in linux we use -1

dev_name is supposed to return the name of the device plus the id
currently we use %s%d format where in the kernel the use %s.%d
we may think to switch to this format for the device name and keeping the %s%d
for the devfs
this will be usefull to not modify the clock device name as example

Change device parameters so that the memory management is in generic
code. This also removes the need of storing statically initialized
parameters as they are stored in a struct list_head for each device.

We accidently have two list implementations in the tree:
include/list.h and include/linux/list.h. This patch moves
the latter (newer one) to include/linux/list.h.

No need to check for maximum argument counts. The commands are
safe to be called with more arguments, so lets safe some bytes.
