This more accurately reflects that "non-zero exit status indicates
failure"; while > 0 will no doubt work as well, != 0 avoids the question
of whether $? is signed or unsigned in bash and more accurately
represents the documentation ("non-zero", != 0).
This patch implements two structural changes.
First, OS-level detection routines are broken out into a case statement.
Darwin doesn't need to test for readlink/timeout nor Busybox, so this
noticeably improves performance over multiple runs on Darwin.
Linux suffers no additional penalty, since we already ran if $(uname)
every time anyways, and continues to use the more complex
timeout/gtimeout/busybox logic at the (preexisting, unaffected) cost to
performance over multiple runs.
Second, if NOAUTODETECT is set, then the script assumes (and verifies)
that you're providing TIMEOUTBIN and OPENSSLBIN values. If both of those
values are executable files, then the script will proceed, else it will
abort. In this scenario, readlink is unnecessary and is thus unused.
The combination of these two changes will improve performance over
multiple runs both on Darwin and when NOAUTODETECT is set for top1m.
This takes advantage of the new --cafile logic to avoid running CACERTS
autodetection when a file is provided on the command line.
It then ensures the readability of that file, whether provided or
autodetected.
This also adds an undocumented CAPATH environment variable alternative
to --capath, to go along with the existing undocumented CACERTS
environment variable alternative to --cafile, to provide legacy support
for preexisting users.
