Built in tracing should _not_ be run if it was not set on purpose. Warn as
loud as we can in order to inform the user that they are running a version
with tracing capabilities built in.
This commit also adds a subsys stub because utlimately the logging will happen
in the init phase but because the default log file is not set in the
sys_logging init function, the stub is not useful for now.

In the next commits, we'll add more tracing options for instrumentation and
specific tracer.
This rename follows a more meaningful naming standard. It also adds a catch
all "HAVE_TRACING" define that indicate in the code that we have tracing
enabled.

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.
Closing these file descriptors can hide sanitiser logs.
Instead, flush the logs before tor exits, using fsync().
Some Windows environments don't have fsync(), so we check
for it at compile time.
Fixes bug 33087; bugfix on 0.4.1.6.
For now, this module is enabled whenever the relay module is
enabled, and disabled whenever the relay module is disabled. Though
they are logically separate, the use cases for running one without
the other are rare enough that we don't really want to support
compiling them independently.
Python 2 will be end-of-life as of 1 Jan 2020, so we can finally
stop supporting it. As a first step, we should make our configure
script stop accepting python 2 as something acceptable to run our
tests with.
Closes ticket 32608.
The "if-present" clause of AC_ARG_ENABLE() sets enable_{lzma,zstd},
so we don't need to set it. The "if-not-present" clause needs to set
enable_{lzma,zstd}, rather than just {lzma,zstd}.
The rest of the script only ever checks for enable_{lzma,zstd} = no,
so these changes do not actually change the behaviour of configure.
Fixes bug 32401.
Up till now, we have warned about all missing documentation, which
meant that we could never make doxygen warnings fatal. This has led
to our doxygen output getting full of errors several times in the
past.
This commit changes our approach to doxygen warnings: missing
documentation warnings are only on when the user asks for them with
--enable-missing-doc-warnings. When that option is not present,
doxygen respects the --enable-fatal-warnings flag.
Closes ticket 32385.
Our @top_srcdir@ directory can contain "..", which confuses doxygen
when it tries to make references to directories. Using
@abs_top_srcdir@ has the same problem. Instead, we should use our
@SRCDIR@ configuration variable, which is canonicalized.
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.

When pkg-config is not installed, or a library that depends on
pkg-config is not found, tell the user what to do to fix the
problem.
Fixes bug 31922; bugfix on 0.3.1.1-alpha.
The #[global_allocator] attribute is not available in versions prior to
1.28.0, the default-linker-libraries feature requires rust 1.31.0.
Adapt the CI to prevent accidental increases in Rust version by testing
against 1.31.0, beta and nightly.
