ivi-shell test suite and bugfixes found by these test cases

[Nobuhiko Tanibata]

Hi,

I am proposing a set of patches; ivi-shell test suite and bug fixes 
found
by these test cases. This test suite is implemented based on following 
test
framework.
http://lists.freedesktop.org/archives/wayland-devel/2015-March/020932.html

This test suite consists of four parts to verify ivi-shell important 
functionalities.
- ivi_surface
- ivi_layer
- ivi_screen
- notification when properties of ivi_surface/layer are changed.


Test set of ivi_surface)
  ivi_surface is created by client by using 
ivi_application::surface_create.
  So I am using helper client to verify lifetime of ivi_surface.
  
http://cgit.freedesktop.org/wayland/weston/tree/protocol/ivi-application.xml

  This test set consists of three patches to verify normal use cases and 
bad
  condition.

  36e2e4e tests: test set for ivi-surface normal use case with helper 
client
  a2aad7d tests: test set for ivi-surface with bad condition in server 
side
  2d2def2 tests: test set for ivi-surface bad condition with helper 
client


Test set of ivi_layer)
  ivi_layer is mainly used by controller module which works on 
server/weston.
  However some tests need client helper to create ivi_surfaces which are
  assigned to ivi_layer.

  4e55d9d tests: test set for ivi-layer normal use case with helper 
client
  c420e06 tests: test set for ivi-layer normal use case in server side
  dde756d tests: test set for ivi-layer bad condition with helper-client
  018e00d tests: test set for ivi-layer with bad condition in server side


Test set of ivi_screen)
  ivi_screen is only used by controller module. So that test case of 
normal
  use cases and bad condition are implemented on server side only.

  b6b098e tests: test set for ivi-screen normal use case in server side
  cbd0aa2 tests: test set for ivi-screen with bad condition in server 
side


Test set of notifications)
  ivi_shell supports features of receiving notification of properties 
change.
  These one needs client helper to create ivi_surfaces as well. These 
test
  set proposes verification of normal use case and bad condition.

  e722bab tests: test set for ivi-shell notification normal use case with 
helper client
  fcef111 tests: test set for ivi-shell notification normal use case in 
server side
  b89f6ea tests: test set for ivi-shell notification in bad condition 
with helper client
  101eb7b tests: test set for ivi-shell notification with bad condition 
in server side
