Add missing documentation for the debugredirect setting.
Add description and uses of gdb.in/gdb.cmd to the testsuite README.
Mention this in the NEWS file.
[Wasn't sure if testsuite changes belonged in NEWS? If not I can
drop that part]

+Re-running Tests Outside The Testsuite
+**************************************
+
+When running a test, the arguments used to run GDB are saved to gdb.cmd and
+all commands sent to GDB are saved to gdb.in. As well as being a reference
+of the commands run, they can be used to manually re-run a test by using
+the gdb.in file as a batch file to a GDB launched with the arguments in the
+gdb.cmd file, for example:
+ $(cat outputs/gdb.base/store/gdb.cmd) -x outputs/gdb.base/store/gdb.in
+
+Tests that run GDB multiple times will append .1, .2, .3 etc to the end
+of each .cmd and .in file.
+
+When gdbserver is launched as part of a test, a gdbserver.cmd will be created.
+To re-run these tests, run the contents of gdbserver.cmd in a separate
+terminal before running gdb, for example:
+ $(cat outputs/gdb.base/store/gdbserver.cmd)
+Alternatively, if the test is run with GDBSERVER_DEBUG="replay", then this
+will create a gdbserver.replay file which can be used with the gdbreplay tool,
+instead of launching gdbserver.
