We had some confusions on when each function was used. We should not act
differently on different locales anyway.

... to make it less likely that we forget that the function actually
does case insentive compares. Also replaced several invokes of the
function with a plain strcmp when case sensitivity is not an issue (like
comparing with "-").

... otherwise example.com/PATH and example.com/path would be assumed to
be the same and they usually aren't!

If the requested size is zero, bail out with error instead of doing a
realloc() that would cause a double-free: realloc(0) acts as a free()
and then there's a second free in the cleanup path.

Previously it only held references to them, which was reckless as the
thread lock was released so the cookies could get modified by other
handles that share the same cookie jar over the share interface.

- Change initial message box to mention delay when downloading/parsing.

Since there is no progress meter it was somewhat unexpected that after
choosing a filename nothing appears to happen, when actually the cert
data is in the process of being downloaded and parsed.

- Warn if OpenSSL is not present.

- Use a UTF-8 stream to make the ca-bundle data.

- Save the UTF-8 ca-bundle stream as binary so that no BOM is added.

---

This is a follow-up to d2c6d156 which switched mk-ca-bundle.vbs output to
ANSI due to corrupt UTF-8 output, now fixed.

This change completes making the default certificate bundle output of
mk-ca-bundle.vbs as close as possible to that of mk-ca-bundle.pl, which
should make it easier to review any difference between their output.

To make it render better on the web site, at the price of it becoming
slightly less readable as text.

- Clarify that this option is only for HTTP/1.1 pipelining.

Some versions of test allow == for equality, but others (such as the HP-UX
version) do not.  Use a single = for correctness.

Error output:
checking for monotonic clock_gettime... ./configure[20445]: ==: A test command parameter is not valid.

- we allow the security push up to 48 hours before the release

- add a mention about possible pre-notifications

Bug: https://bugzilla.redhat.com/1388162

Bring the VBScript version more in line with the perl version:

- Change timestamp to UTC.

- Change URL retrieval to HTTPS-only by default.

- Comment out the options that disabled SSL cert checking by default.

- Assume OpenSSL is present, get SHA256. And add a flag to toggle it.

- Fix cert issuer name output.

The cert issuer output is now ansi, converted from UTF-8. Prior to this
it was corrupt UTF-8. It turns out though we can work with UTF-8 the
FSO object that writes ca-bundle can't write UTF-8, so there will have
to be some alternative if UTF-8 is needed (like an ADODB.Stream).

- Disable the certificate text info feature.

The certificate text info doesn't work properly with any recent OpenSSL.

See #1084

Brought in 1ad2bdcf. Now does HTTPS by default and needs -k to
fall back to plain HTTP.

- Change all predefined Mozilla URLs to HTTPS (Gregory Szorc).

- New option -k to allow URLs other than HTTPS and enable HTTP fallback.

Prior to this change the default URL retrieval mode was to fall back to
HTTP if HTTPS didn't work.
