runtests: create multiple test runners when requested
Parallel testing is enabled by using a nonzero value for the -j option
to runtests.pl. Performant values seem to be about 7*num CPU cores, or
1.3*num CPU cores if Valgrind is in use.
Flaky tests due to improper log locking (bug #11231) are exacerbated
while parallel testing, so it is not enabled by default yet.

Each runner needs a unique random seed to reduce the chance of port
number collisions. The new scheme uses a consistent per-runner source of
randomness which results in deterministic behaviour, as it did before.

tests/servers.pm: pick unused port number with a server socket
This change replaces the previous method of picking a port number at
random to try to start servers on, then retrying up to ten times with
new random numbers each time, with a function that creates a server
socket on port zero, thereby getting a suitable random port set by the
kernel. That server socket is then closed and that port number is used
to setup the actual test server on.
There is a risk that *another* server can be started on the machine in
the time gap, but the server verification feature will detect that.
If you try to assign and export on the same line on some older /bin/sh
implementations, it complains:
```
$ export "NAME=value"
NAME=value: is not an identifier
```
This commit rewrites run-compiler's assignments and exports to work with
old /bin/sh, splitting assignment and export into two separate
statements, and only quote the value. So now we have:
```
NAME="value"
export NAME
```
While we're here, make the same change to the two supporting
assign+export lines preceeding the script to be consistent with how
exports work throughout the rest of configure.ac.

they better avoid nick names not intended for credits. Such names are
not too commonly used, plus we now give credit even to those.
Additionally: non-latin names, like Asian, don't have spaces at all so
they were also filtered out and had to be manually added which made it
an error-prone operation where Asian names eventually easily fell off by

configure: fix build with arbitrary CC and LD_LIBRARY_PATH
Since ./configure and processes that inherit its environment variables
are the only callers of the run-compiler script, we can just save the
current value of the LD_LIBRARY_PATH and CC variables to another pair of
environment variables, and make run-compiler a static script that
simply restores CC and LD_LIBRARY_PATH to the saved value, and before
running the compiler.
This avoids having to inject the values of the variables in the script,
possibly causing problems if they contains spaces, quotes, and other
special characters.
Also add exports in the script just in case LD_LIBRARY_PATH and CC are
not already in the environment.

http2: fix EOF handling on uploads with auth negotiation
- doing a POST with `--digest` does an override on the initial request
with `Content-Length: 0`, but the http2 filter was unaware of that
and expected the originally request body. It did therefore not
send a final DATA frame with EOF flag to the server.
- The fix overrides any initial notion of post size when the `done_send`
event is triggered by the transfer loop, leading to the EOF that
is necessary.
- refs #11194. The fault did not happen in testing, as Apache httpd
never tries to read the request body of the initial request,
sends the 401 reply and closes the stream. The server used in the
reported issue however tried to read the EOF and timed out on the
request.

http/2: unstick uploads
- refs #11157 and #11175 where uploads get stuck or lead to RST streams
- fixes our h2 send behaviour to continue sending in the nghttp2 session
as long as it wants to. This will empty our send buffer as long as
the remote stream/connection window allows.
- in case the window is exhausted, the data remaining in the send buffer
will wait for a WINDOW_UPDATE from the server. Which is a socket event
that engages our transfer loop again
- the problem in the issue was that we did not exhaust the window, but
left data in the sendbuffer and no further socket events did happen.
The server was just waiting for us to send more.
- relatedly, there was an issue fixed that closing a stream with KEEP_HOLD
set kept the transfer from shutting down - as it should have - leading
to a timeout.

Revert "urlapi: respect CURLU_ALLOW_SPACE and CURLU_NO_AUTHORITY for redirects"
This reverts commit df6c2f7b544f1f35f2a3e0be11f345affeb6fe9c.
(It only keep the test case that checks redirection to an absolute URL
without hostname and CURLU_NO_AUTHORITY).
I originally wanted to make CURLU_ALLOW_SPACE accept spaces in the
hostname only because I thought
curl_url_set(CURLUPART_URL, CURLU_ALLOW_SPACE) was already accepting
them, and they were only not being accepted in the hostname when
curl_url_set(CURLUPART_URL) was used for a redirection.
That is not actually the case, urlapi never accepted hostnames with
spaces, and a hostname with a space in it never makes sense.
I probably misread the output of my original test when I they were
normally accepted when using CURLU_ALLOW_SPACE, and not redirecting.
Some other URL parsers seems to allow space in the host part of the URL,
e.g. both python3's urllib.parse module, and Chromium's javascript URL
object allow spaces (chromium percent escapes the spaces with %20),
(they also both ignore TABs, and other whitespace characters), but those
URLs with spaces in the hostname are useless, neither python3's requests
module nor Chromium's window.location can actually use them.
There is no reason to add support for URLs with spaces in the host,
since it was not a inconsistency bug; let's revert that patch before it
makes it into release. Sorry about that.
I also reverted the extra check for CURLU_NO_AUTHORITY since that does
not seem to be necessary, CURLU_NO_AUTHORITY already worked for
redirects.
