tests: Avoid WTERMSIG($?) in rx/perf-t
Currently, tests/rx/perf-t calls functions like WIFSIGNALED and WTERMSIG on $?. However, functions like WTERMSIG expect the native exit status code (that is, ${^CHILD_ERROR_NATIVE}). The $? var (aka $CHILD_ERROR), is a synthetic value calculated by perl that stores the term sig in the lowest 7 bits, and the exit code in the second-lowest 8 bits. For most modern platforms, these two values tend to be the same. But on modern AIX (and some other weird platforms, like VMS and BeOS), the exit status integer is encoded differently. On AIX specifically, the term sig is in the third-lowest 8 bits, so a process exiting on signal 15 would result in an exit status (${^CHILD_ERROR_NATIVE}) of 0xf000f, but $? would be just 0xf. Calling WTERMSIG on 0xf000f returns 0xf, but calling WTERMSIG on 0xf returns 0x0. All of this means that running rx/perf-t causes the final test to fail with "Server died with signal 0" (even when the process was killed by signal 15), which is rather confusing. To fix this, call WTERMSIG et al with ${^CHILD_ERROR_NATIVE} instead of $?. Create a local var so we don't need to spell out ${^CHILD_ERROR_NATIVE} so many times.

AFS is a distributed file system that enables users to share and access all of the files stored in a network of computers as easily as they access the files stored on their local machines. The file system is called distributed for this exact reason: files can reside on many different machines, but are available to users on every machine. OpenAFS 1.0 was originally released by IBM under the terms of the IBM Public License 1.0 (IPL10). For details on IPL10 see the LICENSE file in this directory. The current OpenAFS distribution is licensed under a combination of the IPL10 and many other licenses as granted by the relevant copyright holders. The LICENSE file in this directory contains more details, thought it is not a comprehensive statement. See INSTALL for information about building and installing OpenAFS on various platforms. See CODING for developer information and guidelines. See NEWS for recent changes to OpenAFS.
