Subject: 	- Support printing refcounted pointers to ostreams. When
X-Git-Tag: SQUID_3_0_PRE6~135
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7c36d157827dad3bd98870497df369dd981c3f67;p=thirdparty%2Fsquid.git

	- Support printing refcounted pointers to ostreams. When
	  printing, report the reference count after the raw pointer.
	  This makes debugs() statements simpler and their output more
	  informative. Null pointers are printed as a "NULL" string.
