The tftpd server may still be busy if the total timeout of
25 seconds has not been reached or no sread error was received
during or after the execution of the timeout test 1238.
Once the next TFTP test comes around (eg. 1242 or 1243),
those will fail because the tftpd server is still waiting
on data from curl due to the UDP protocol being stateless
and having no connection close. On Linux this error may not
happen, because ICMP errors generated due to a swrite error
can also be returned async on the next sread call instead.
Therefore we will now just kill the tftpd server after test
1238 to make sure that the following tests are not affected.
This enables us to no longer ignore tests 1242, 1243, 2002
and 2003 on the CI platforms CirrusCI and AppVeyor.

Closes#5364
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 also makes sure that the progess callback gets called more
often during TFTP transfers.
Added test 1238 to verify.
