Subject[PATCH] create a kstrdup library function

Hi,

This patch creates a new kstrdup library function and changes the
"local" implementations in several places to use this function.

This is just a cleanup to allow reusing the strdup code, and to prevent
bugs in future duplications of strdup.

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.
