- added typedef unsigned int __nocast gfp_t;
- replaced __nocast uses for gfp flags with gfp_t - it gives exactly
the same warnings as far as sparse is concerned, doesn't change
generated code (from gcc point of view we replaced unsigned int with
typedef) and documents what's going on far better.

This patch creates a new kstrdup library function and changes the "local"
implementations in several places to use this function.
Most of the changes come from the sound and net subsystems. The sound part
had already been acknowledged by Takashi Iwai and the net part by David S.
Miller.
I left UML alone for now because I would need more time to read the code
carefully before making changes there.

There's a subtle problem with "inline" usage in <linux/string.h>:
<linux/string.h>:
this pulls in __constant_c_and_count_memset()
<linux/mm.h>:
this pulls <compiler.h>, re-defining
inline == __inline__ __attribute__((always_inline)).
But by now it is too late! The compiler has already seen the bare
"inline" in string.h, and hasn't inlined it.
Result:
# grep __constant System.map
c0144670 t __constant_c_and_count_memset
c0145c60 t __constant_c_and_count_memset
... many more copies of this function ...
Fixed by including <compiler.h> early enough.

Convert dev_alloc_name from O(n^2) lookup to O(n) by using a page as
bitmap to figure out how many devices of that pattern have been allocated.
This works for up to 32k devices (PAGE_SIZE*8) on i386, more on other
platforms. Correctly handles the boundary cases where number of devices
won't fit because name length is limited.
Adds strnchr to the string libraries since we need to find the % format
character, but only care if it is in the first 15 bytes.
