README.syncevolution-server: explains testing SyncEvolution<->SyncEvolution

This focuses on the setup that was used for testing suspend/resume
support (Bugzilla #2425). Clients and server use file backends.

+Here are some quick (and probably incomplete) notes about setting up
+SyncEvolution as HTTP server for client-test runs using just the local
+account and machine.
+
+# 1. run client-test like this:
+CLIENT_TEST_SERVER=syncevolution --help
+
+# 2. set the URL (using IPv4 here, in case that "localhost" expands to IPv6, which
+#    can be problematic):
+for i in 1 2; do
+   syncevolution --configure --sync-property syncURL=http://127.0.0.1:9000/syncevolution syncevolution_$i
+done
+
+# 3. configure the server, using a separate context with the four standard URIs
+#    implemented via files in /tmp, no credential checking, maximum message size
+#    which forces the clients to split items (makes testInterruptResume*Big more
+#    interesting), low timeout to keep tests going quickly, with device IDs as
+#    set by client-test-app.cpp in step 1:
+for i in 1 2; do
+   syncevolution --configure --template SyncEvolutionClient \
+                 --sync-property username= \
+                 --sync-property password= \
