configure: set classic mingw minimum OS version to XP

- If the user has not specified a minimum OS version (via WINVER or
_WIN32_WINNT macros) then set it to Windows XP.

Prior to this change classic MinGW defaulted the minimum OS version
to Windows NT 4.0 which is way too old. At least Windows XP is needed
for getaddrinfo (which resolves hostnames to IPv6 addresses).

schannel: Work around typo in classic mingw macro

- Define ALG_CLASS_DHASH (the typo from the include) to ALG_CLASS_HASH.

Prior to this change there was an incomplete fix to ignore the
CALG_TLS1PRF macro on those versions of MinGW where it uses the
ALG_CLASS_DHASH typoed macro.

tests/*server.pl: flush output before executing subprocess

Also avoid shell processes staying around by using exec.
This is necessary to avoid output data being buffering
inside the process chain of Perl, Bash/Shell and our
test server binaries. On non-Windows systems the exec
will also make the subprocess replace the intermediate
shell, but on Windows it will at least bind the processes
together since there is no real fork or exec available.

tool_operate: Fix --fail-early with parallel transfers

- Abort via progress callback to fail early during parallel transfers.

When a critical error occurs during a transfer (eg --fail-early
constraint) then other running transfers will be aborted via progress
callback and finish with error CURLE_ABORTED_BY_CALLBACK (42). In this
case, the callback error does not become the most recent error and a
custom error message is used for those transfers:

curld --fail --fail-early --parallel
https://httpbin.org/status/404 https://httpbin.org/delay/10

curl: (22) The requested URL returned error: 404
