PATCH: named pipe server refcounting

[Marcus Meissner <marcus@jet.franken.de>]

Hi,

If I kill a thread with a named pipe still open (like with 'killall wine'),
the wineserver crashes while accessing a freed thread structure.

This patch adds refcounting for the thread structure, dunno if it is
correct.

Ciao, Marcus

Changelog:
	Add refcounting to the thread member of the pipe user.
