To: ltp
Check-in a couple of semantic patches used for removing the TEST macro
from the library. Also include a shell script to run them with a
working set of arguments.
These are only intended to help someone develop their own refactoring
or check scripts. Not for running automatically.

V3:
* Make proper shell script to run spatch
* Fix some issues people would likely encounter with semantic patches
V2:
* Simplify the Cocci scripts
* Simplify the patchset and combine it with the separate CGroups patch
* Testing & sign-off

The test author is guaranteed that the LTP library will not change the
TST_RET and TST_ERR global variables. That way the test author can use
the TEST macro then call other library functions before using TST_RET,
TST_ERR or TTERRNO.

I've did a careful review and this part is actually not correct. The
tst_rtnl_send_validate() function uses TST_ERR to propagate error while
the caller calls tst_rtnl_destroy_context() before it reads the value.
It's not correct to use errno this way since it may be modified in the
functions that free messages or destroys the context.
I guess that fixing this part correctly would mean to change the
tst_rtnl_send_validate() to return the return value from
tst_rtnl_check_acks() and the tst_rtnl_check_acks() would have to return
error on a failure.
It may also make sense to split this patch into two and keep changes to
these two files in a separate patch, since the rest is more or less
mechanical replacement of the TEST() macro use which is as far as I can
tell correct.
