Initial revision

Import ATF 0.6. Replaces the old ATF 0.5 that was in dist/atf.

Changes in this release:

* Make atf-exec be able to kill its child process after a certain period of
time; this is controlled through the new -t option.

* Change atf-sh to use atf-exec's -t option to control the test case's
timeouts, instead of doing it internally. Same behavior as before, but
noticeably faster.

* atf-exec's -g option and atf-killpg are gone due to the previous change.

* Added the atf-check(1) tool, a program that executes a given command and
checks its exit code against a known value and allows the management of
stdout and stderr in multiple ways. This replaces the previous atf_check
function in the atf-sh library and exposes this functionality to both
atf-c and atf-c++.

* Added the ATF_REQUIRE family of macros to the C interface. These help
in checking for fatal test conditions. The old ATF_CHECK macros now
perform non-fatal checks only. I.e. by using ATF_CHECK, the test case
can now continue its execution and the failures will not be reported
until the end of the whole run.

* Extended the amount of ATF_CHECK_* C macros with new ones to provide more
features to the developer. These also have their corresponding
counterparts in the ATF_REQUIRE_* family. The new macros (listing the
suffixes only) are: _EQ (replaces _EQUAL), _EQ_MSG, _STREQ and
_STREQ_MSG.
