On an overloaded server, the default 1 second timeout can go by without
the test server having a chance to respond with the expected headers,
causing tests to fail. Increase the 1 second timeout to 99 seconds so
this failure mode is no longer a problem on test 1129. Some other tests
already set a high value, but make them consistently 99 seconds so if
something goes wrong the test is stalled for less time.
Ref: #11328
The threee tags `<name>`, `</name>` and `<command>` were frequently used
with a leading space that this removes. The reason this habbit is so
widespread in testcases is probably that they have been copy and pasted.
Hence, fixing them all now might curb this practice from now on.
Closes#12028
"Connection: close" and actually close the connection after the
response-body, libcurl could still have outstanding data to send and it
would not properly notice this and stop sending. This caused weirdness and
sad faces. http://curl.haxx.se/bug/view.cgi?id=2080222
Note that there are still reasons to consider libcurl's behavior when
getting a >= 400 response code while sending data, as Craig Perras' note
"http upload: how to stop on error" specifies:
