[Piglit] [PATCH v1 1/2] piglit-framework-gl: add possibility to deinit test

[Sergii Romantsov]

Each test can be initialized ('init') and displayed ('dipslay').
During initialization can be allocated resources.
But there is no common unified mechanism to free resources on test
finishing, except, probably, registaration of callabck with 'atexit'.

To the piglit-configuration added callback-function 'deinit' that
will be called on the test end.
