[Skunkweb-list] skunkweb build fails under osx

[Frederick G. <fg...@bu...>]

Howdy List,
	The build fails on OSX due to a previously defined uuid_t struct in / 
usr/include/unistd.h.  I have attached a patch that changes the named  
uuid_t in pylibs/uuid/dav_opaquelock.h, pylibs/uuid/dav_opaquelock.c,  
pylibs/uuid/_uuidmodule.c, and to sk_uuid_t which compiles without  
issue.

	Thanks much,
	Fred
