OTP-8703 peppe/common_test_r14_dev_2

Directories added with run_test -pa or -pz in the pre erl_args part of the command line will be converted from relative to absolute, this to avoid confusion when Common Test switches working directory during the test run.

Also fixed in this commit: Problem with timeouts during init_tc or end_tc (in the Test Server framework).

Also fixed bug in test_server that calls end_per_testcase after test case timeout or abortion.

Also fixed bug: return value {fail,Reason} from end_tc(init_per_suite) was ignored.

Documentation still missing.
