mDNSResponder: Update to v765.1.2

The sources can be obtained via:

https://opensource.apple.com/tarballs/mDNSResponder/mDNSResponder-765.1.2.tar.gz

Move mDNS_StartResolveService() and mDNS_StopResolveService() to an
RTEMS-specific file (rtemsbsd/mdns/mDNSResolveService.c) using the
v576.30.4 implementation.  Apple removed these functions without
explanation.

Update #3522.

+Three steps to attach, and debug in Xcode, a /usr/sbin/mDNSResponder that is already running.  One caveat, mDNSResponder has to be built and deployed (using step 1 and 2 below) before it can be attached to Xcode.\
+\
+1.) First you have to build the Xcode project with symbols included and optimizations off.\
+\
+	a.) From Terminal shell, open mDNSResponder Xcode project from top of tree: \'a0\
+\
+		$ open mDNSMacOSX/mDNSResponder.xcodeproj/\
+\
+\pard\pardeftab720\partightenfactor0
+\cf0 	You can also just double click on the project from Finder.\
+\
+	b.) Add your diffs to mDNSResponder project.
+\f1\fs22 \
+\pard\pardeftab720\partightenfactor0
+
+\f0\fs24 \cf0 \
+	c.) Set Strip Linked Product to No and compiler Optimization Level to None.  Below shows changed settings.\

+	d. ) Build mDNSResponder by setting the target to mDNSResponder.\
+\

+}¬}\
+\
+	Then execute\'a0Command-B to build.\
+\
+\
+2.) Next, deploy newly-created Xcode version.\
+\
+	a.)  Go to Terminal shell and type the following:  sudo mv \
+\
+	b.) Then drag mDNSResponder from Products list on left side panel (shown below using red arrow) to Terminal shell.\

+\cf0 \
+\

+\

+\
+	d.) Restart mDNSResponder by executing the following:\
+\
+	$ sudo killall mDNSResponder\
+\pard\pardeftab720\partightenfactor0
+
+\f1\fs22 \cf0 \
+\
+\pard\pardeftab720\partightenfactor0
+
+\f0\fs24 \cf0 3.) In Xcode, select Debug > Attach to Process > mDNSResponder. 
+\f1\fs22 \
+
+\f0\fs24 \
+	Now set a breakpoint and try to trigger it.\
