This warning only affects platforms (like win32) with 32-bit time_t.
Fixes bug 40028; bugfix on 0.3.2.8-rc.

For some reasons, Appveyor started to use the stdio printf format for 64 bit
values (PRIu64, ...). Mingw doesn't like that so force it to use the Windows
specific macros by setting D__USE_MINGW_ANSI_STDIO=0.
Fixes #40026

This patch changes our bits-to-bytes conversion logic in the NSS
implementation of `tor_tls_cert_matches_key()` from using (x >> 3) to
((x + 7) >> 3) since DER bit-strings are allowed to contain a number of
bits that is not a multiple of 8.
Additionally, we add a comment on why we cannot use the
`DER_ConvertBitString()` macro from NSS, as we would potentially apply
the bits-to-bytes conversion logic twice, which would lead to an
insignificant amount of bytes being compared in
`SECITEM_ItemsAreEqual()` and thus turn the logic into being a
prefix match instead of a full match.
The `DER_ConvertBitString()` macro is defined in NSS as:
/*
** Macro to convert der decoded bit string into a decoded octet
** string. All it needs to do is fiddle with the length code.
*/
#define DER_ConvertBitString(item) \
{ \
(item)->len = ((item)->len + 7) >> 3; \
}
Thanks to Taylor Yu for spotting this problem.

We add constness to `peer_info_orig_len` and `cert_info_orig_len` in
`tor_tls_cert_matches_key` to ensure that we don't accidentally alter
the variables.

This patch fixes an out-of-bound memory read in
`tor_tls_cert_matches_key()` when Tor is compiled to use Mozilla's NSS
instead of OpenSSL.
The NSS library stores some length fields in bits instead of bytes, but
the comparison function found in `SECITEM_ItemsAreEqual()` needs the
length to be encoded in bytes. This means that for a 140-byte,
DER-encoded, SubjectPublicKeyInfo struct (with a 1024-bit RSA public key
in it), we would ask `SECITEM_ItemsAreEqual()` to compare the first 1120
bytes instead of 140 (140bytes * 8bits = 1120bits).
This patch fixes the issue by converting from bits to bytes before
calling `SECITEM_ItemsAreEqual()` and convert the `len`-fields back to
bits before we leave the function.

This patch lifts the `tor_tls_cert_matches_key()` tests out of the
OpenSSL specific TLS test suite and moves it into the generic TLS test
suite that is executed for both OpenSSL and NSS.
This patch is largely a code movement, but we had to rewrite parts of
the test to avoid using OpenSSL specific data-types (such as `X509 *`)
and replace it with the generic Tor abstraction type
(`tor_x509_cert_impl_t *`).
This patch is part of the fix for TROVE-2020-001.

This is not actually a bug! It can happen for a bunch of reasons,
which all boil down to "trying to add an extrainfo for which we no
longer have the corresponding routerinfo".
Fixes #16016; bugfix on 0.2.6.3-alpha.

This patch makes sures that AppVeyor upgrades its Pacman (the package
manager) before installing the Tor dependencies.

This reverts commit e63bfca5f2d98788d11b9a0a82bf67277a228c71, now
that Stem has been upgraded to fix the underlying issue.

Resume being willing to use preemptively-built circuits when
UseEntryGuards is set to 0. We accidentally disabled this feature with
that config setting (in our fix for #24469), leading to slower load times.
Fixes bug 34303; bugfix on 0.3.3.2-alpha.

Fixes bug 34233.
(This has bug has been backported to 0.3.5, but only released in
0.4.3, so it only needs a changes file there.)

GCC added an implicit-fallthrough warning a while back, where it
would complain if you had a nontrivial "case:" block that didn't end
with break, return, or something like that. Clang recently added
the same thing.
GCC, however, would let you annotate a fall-through as intended by
any of various magic "/* fall through */" comments. Clang, however,
only seems to like "__attribute__((fallthrough))". Fortunately, GCC
accepts that too.
A previous commit in this branch defined a FALLTHROUGH macro to do
the right thing if GNUC is defined; here we replace all of our "fall
through" comments with uses of that macro.
This is an automated commit, made with the following perl one-liner:
#!/usr/bin/perl -i -p
s#/\* *falls? ?thr.*?\*/#FALLTHROUGH;#i;

This macro defers to __attribute__((fallthrough)) on GCC (and
clang). Previously we had been using GCC's magic /* fallthrough */
comments, but clang very sensibly doesn't accept those.
Since not all compiler recognize it, we only define it when our
configure script detects that it works.
Part of a fix for 34078.
