Add deinitialization function ipatch_deinit()

[jjceresa]

The new function ipatch_deinit()is incorporated in ipatch_close() function API.

• Typically the application should call ipatch_init()before using any other functions.
• Then the application should call ipatch_close()when finished. This ensures freeing the memory allocated during ipatch_init().

Note: ipatch_deinit() has been incorporated inipatch_close()because ipatch_close() is already a function API. This avoid changing actual version number.

I guess we should also call it in Swami

Yes, the same thing will be done in libswami and libswamigui (this is currently in progress).
