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
Stop checking the timeout used by the client under test (for most
tests). The timeout will change if the TFTP test server is slow (such as
happens on an overprovisioned CI server) because the client will retry
and reduce its timeout, and the actual value is not important for most
tests.
test285 is changed a different way, by increasing the connect timeout.
This improves test coverage by allowing the changed timeout value to be
checked, but improves reliability with a carefully-chosen timeout that
not only allows twice the time to respond as before, but also allows
several retries before the client will change its timeout value.

By making them look less like http headers, the hyper mode "tweak"
doesn't interfere.
Enable test 2002 and 2003 in hyper builds (and 1280 which is unrelated
but should be enabled).
Closes#7658
The tftpd test server now logs all received options and thus all TFTP
test cases need to match them exactly.
Extended test 283 to use and verify --tftp-blksize.
This happened because the tftp code always uncondionally did a bind()
without caring if one already had been done and then it failed. I wrote a
test case (1009) to verify this, but it is a bit error-prone since it will
have to pick a fixed local port number and since the tests are run on so
many different hosts in different situations I add it in disabled state.
