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.

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.

FTP, IMAP, POP3, SMTP and their IPv6 versions are now all on dynamic
ports
Test 842-845 are unfortunately a bit hard to move over to this concept
right now and require "default port" still...
The runtests script now always performs variable replacement on the
entire test source file before the test gets executed, and saves the
updated version in a temporary file (log/test[num]) so that all test
case readers/servers can use that version (if present) and thus enjoy
the powers of test case variable substitution.
This is necessary to allow complete port number freedom.
Test 309 is updated to work with a non-fixed port number thanks to this.
Since the Windows versions of both programs would write Windows

- Implement new option CURLSSLOPT_REVOKE_BEST_EFFORT and
--ssl-revoke-best-effort to allow a "best effort" revocation check.
A best effort revocation check ignores errors that the revocation check
was unable to take place. The reasoning is described in detail below and
discussed further in the PR.
---
When running e.g. with Fiddler, the schannel backend fails with an
unhelpful error message:
Unknown error (0x80092012) - The revocation function was unable
to check revocation for the certificate.
Sadly, many enterprise users who are stuck behind MITM proxies suffer
the very same problem.
This has been discussed in plenty of issues:
https://github.com/curl/curl/issues/3727,
https://github.com/curl/curl/issues/264, for example.
In the latter, a Microsoft Edge developer even made the case that the
common behavior is to ignore issues when a certificate has no recorded
distribution point for revocation lists, or when the server is offline.
This is also known as "best effort" strategy and addresses the Fiddler
issue.
Unfortunately, this strategy was not chosen as the default for schannel
(and is therefore a backend-specific behavior: OpenSSL seems to happily
ignore the offline servers and missing distribution points).
To maintain backward-compatibility, we therefore add a new flag
(`CURLSSLOPT_REVOKE_BEST_EFFORT`) and a new option
(`--ssl-revoke-best-effort`) to select the new behavior.
Due to the many related issues Git for Windows and GitHub Desktop, the
plan is to make this behavior the default in these software packages.
The test 2070 was added to verify this behavior, adapted from 310.
