Stack overflows can occur with precisions for integers and floats.
Proof of concepts:
- curl_mprintf("%d, %.*1$d", 500, 1);
- curl_mprintf("%d, %+0500.*1$f", 500, 1);
Ideally, compile with -fsanitize=address which makes this undefined
behavior a bit more defined for debug purposes.
The format strings are valid. The overflows occur due to invalid
arguments. If these arguments are variables with contents controlled
by an attacker, the function's stack can be corrupted.
Also see CVE-2016-9586 which partially fixed the float aspect.

timeval::tv_usec might be a 32-bit integer and timespec::tv_nsec might
be a 64-bit integer. This is the case when building for recent macOS
versions, for example. Just treat tv_usec as an int, which should
hopefully always be sufficient on systems with
`HAVE_CLOCK_GETTIME_MONOTONIC`.

This test verifies the -w %json output and the test case includes a full

* runtests.pl:
- Fix out-of-tree build under CMake when srcdir is not set. Default
srcdir to the location of runtests.pl.
- Add a hack to allow CMake to use the TFLAGS option as documented
in tests/README and used in scripts/travis/script.sh.
* Bump CMake version to 3.2 for USES_TERMINAL, dropping Debian Jessie
support (no one should care, it is already EOL.).
* Remove CTest since it defines its own 'test' target with no tests
since all unittests are already broken and not built by default.
* Add new test targets based on the options from Makefile.am. Since
new test targets are rarely added, I opted for duplicating the
runtests.pl options as opposed to creating a new Makefile.inc file.
Use top-level target names (test-x) instead of x-test since that is
used by CI and others.

The default target should only build libcurl and curl. Add a dedicated

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.

Several tests referred to specific server ports even when the test
didn't actually use that server or specify that it's needed. In such
cases, the test harness substitutes the text "[not running]" as the port
number which causes many such tests to fail due to the inability to
parse the URL. These tests are changed to use %NOLISTENPORT which will
always be substituted correctly.

Prior to this change if there was a 303 reply to a PUT request then
the subsequent request to respond to that redirect would also be a PUT.
It was determined that was most likely incorrect based on the language
of the RFCs. Basically 303 means "see other" resource, which implies it
is most likely not the same resource, therefore we should not try to PUT
to that different resource.
