jvpp: introducing callback api and future api tests for all plugins (VPP-591)

test can be run with:
make test TEST=test_jvpp

memory_shared.c:
declaring and assigning variable in if statement
makes it usage outside statement impossible. Looks like memory
space assigned to variable declared in statement is freed when
statement ends
svm.c:
- fixed case when root path can have a "/" at beggining
- added option for test to operate over shared memory space
with /vpe-api name and not create new one with name consisting of
root path and region name which would require root permisions

+This package contains basic tests for jvpp. To run the tests:
+
+- Make sure VPP is running
+- From VPP's build-root/ folder execute:
+  - release version: sudo java -cp build-vpp-native/vpp/vpp-api/java/jvpp-registry-17.10.jar:build-vpp-native/vpp/vpp-api/java/jvpp-core-17.10.jar io.fd.vpp.jvpp.core.test.[test name]
+  - debug version: sudo java -cp build-vpp_debug-native/vpp/vpp-api/java/jvpp-registry-17.10.jar:build-vpp_debug-native/vpp/vpp-api/java/jvpp-core-17.10.jar io.fd.vpp.jvpp.core.test.[test name]
+
+Available tests:
+CallbackApiTest - Similar to ControlPingTest, invokes more complex calls (e.g. interface dump) using low level JVpp APIs
+CallbackJVppFacadeNotificationTest - Tests interface notifications using Callback based JVpp facade
+CallbackJVppFacadeTest - Execution of more complex calls using Callback based JVpp facade
+CallbackNotificationApiTest - Tests interface notifications using low level JVpp APIs
+ControlPingTest - Simple test executing a single control ping using low level JVpp APIs
+CreateSubInterfaceTest - Tests sub-interface creation
+FutureApiNotificationTest - Tests interface notifications using Future based JVpp facade
+FutureApiTest - Execution of more complex calls using Future based JVpp facade
+L2AclTest - Tests L2 ACL creation
+LispAdjacencyTest - Tests lisp adjacency creation and read (custom vpe.api type support showcase)
