Require C99 standards-conforming code in Travis CI, but allow GNU gcc
extensions. Also activates clang's -Wtypedef-redefinition warnings.
Builds some jobs with -std=gnu99, and some jobs without.
Closes ticket 32500.
Install the mingw OpenSSL package in Appveyor. This makes sure that
the OpenSSL headers and libraries match in Tor's Appveyor builds.
(This bug was triggered by an Appveyor image update.)
Fixes bug 32449; bugfix on 0.3.5.6-rc.
Doing so caused us to crash in some unusual circumstances, such as
using --verify-config to verify a configuration that failed during
the options_act() stage.
Fixes bug 32407; bugfix on 0.3.3.1-alpha.
This check was accidentally disabled by a bad find command.
Fixes bug 32402; bugfix on 0.4.2.1-alpha.
Obviously correct changes to already reviewed code.
The current pkg-config setup has no sense of whether it is cross-compiling,
so it will detect things on the build system that are not present or are
wrong for the host system. This forces the cross-compiling build to only
look for pkg-config .pc files in --prefix.
A version of this has been the setup for many years with the Android builds.

Before inspecting the p_chan, we must check if the circuit is marked for close
because if it is the case, the channels are nullified from the circuit.
Several valid cases can mark the circuit for close of the directory
connection.

hs_client_purge_state() and hs_cache_clean_as_client() can remove a descriptor
from the client cache with a NEWNYM or simply when the descriptor expires.
Which means that for an INTRO circuit being established during that time, once
it opens, we lookup the descriptor to get the IP object but hey surprised, no
more descriptor.
The approach here is minimalist that is accept the race and close the circuit
since we can not continue. Before that, the circuit would stay opened and the
client wait the SockTimeout.

Our minimum version is now 0.2.9.5-alpha. Series 0.3.0, 0.3.1,
0.3.2, 0.3.3, and 0.3.4 are now rejected.
Also, extract this version-checking code into a new function, so we
can test it.
Closes ticket 31549.
Also reject 0.3.5.0 through 0.3.5.6-rc as unstable.
Make clear in the man page, in both the bandwidth section and the
accountingmax section, that Tor counts in powers of two, not
powers of ten: 1 GByte is 1024*1024*1024 bytes, not one billion
bytes.
Resolves ticket 32106.
Relays now respect their AccountingMax bandwidth again. When relays
entered "soft" hibernation (which typically starts when we've hit
90% of our AccountingMax), we had stopped checking whether we should
enter hard hibernation. Soft hibernation refuses new connections and
new circuits, but the existing circuits can continue, meaning that
relays could have exceeded their configured AccountingMax.
This commit rolls back some of the cpu-saving fixes, where we tried
to avoid calling so many of our events while we're off the network.
That's because PERIODIC_EVENT_FLAG_NEED_NET checks net_is_disabled(),
which returns true even if we're only in soft hibernation.
Fixes bug 32108; bugfix on 0.4.0.1-alpha.
* actually sleep when tor has not logged anything
* log at debug level when waiting for tor to log something
* backslash-replace bad UTF-8 characters in logs
* format control messages as ASCII: tor does not accept UTF-8 control commands
Fixes bug 31837; bugfix on 0.3.5.1-alpha.
This patch removes an overly strict tor_assert() and an ignorable BUG()
expression. Both of these would trigger if a PT was unable to configure
itself during startup. The easy way to trigger this is to configure an
obfs4 bridge where you make the obfs4 process try to bind on a port
number under 1024.

This patch removes a call to tor_assert_unreached() after execve()
failed. This assertion leads to the child process emitting a stack trace
on its standard output, which makes the error harder for the user to
demystify, since they think it is an internal error in Tor instead of
"just" being a "no such file or directory" error.
The process will now instead output "Error from child process: X" where
X is the stringified version of the errno value.

When tearing down all periodic events during shutdown, disable them first so
their enable flag is updated.
This allows the tor_api.h to relaunch tor properly after a clean shutdown.

Also add a comment in connection_mark_for_close_internal_() on why we should
not be adding extra code there without a very good reason.
