Deal with tiny "HTTP/0.9" (header-less) responses by checking the
status-line early, even before a full "HTTP/" is received to allow
detecting 0.9 properly.

Test 1266 and 1267 added to verify.

Split off testing file names with double quotes into new test 1158.
Disable it for MSYS using a precheck as it doesn't support file names
with double quotes (but Cygwin does, for example).

- Determine if perl is in the user's PATH by running perl.exe.

Prior to this change detection was done by checking the PATH for perl/
but that did not work in all cases (eg git install includes perl but
not in perl/ path).

On Windows, casting between unrelated function types is fine and
sometimes even necessary, so just use an intermediate cast to

Closes #2857

Previously, the macro TEST_HANG_TIMEOUT was unused, but since there is
looping going on, we might as well add timing instead of removing it.

Closes #2853

The macro has never been used, and it there is not really any place
where it would make sense to add timing checks.

Closes #2852

The macro seems to never have been used.

This allows the use of PKCS#11 URI for certificates and keys without
setting the corresponding type as "ENG" and the engine as "pkcs11"
explicitly. If a PKCS#11 URI is provided for certificate, key,
proxy_certificate or proxy_key, the corresponding type is set as "ENG"
if not provided and the engine is set to "pkcs11" if not provided.

addresses is only used in an infof call, which is a macro expanding to

Turns out that since we're using the native fnmatch function now when
available, and they simply disagree on a huge number of test patterns
that make it hard to test this function like this...
