This is currently for the dircache module that can not be disabled by itself,
it is only disabled from the relay module.
Thus, we should not print in the configure summary the disable option.

From c618c4f279, we changed the static
libevent.a path to be able to use the git repository or tarball directly but
that broke the "make install" setup that Tor Browser is using with Android.
In other words, the git repository and tarball put the "libevent.a" in
".libs/" where "make install" puts it in "lib/".
Using the --with-libevent-dir=..., which is mandatory for static libevent,
autoconf will take the path and use it for the includes (-I) and library (-L)
for which if it finds a "include/" and a "lib/" in the root, it will use
those.
However, with the git repo or tarball, the "lib/" doesn't exists thus autoconf
sets the library search path to be at the root and thus fails to find the
libevent.a in ".libs/".
This is a whole lot more work to make both cases work in our configure.ac thus
I'm reverting the change here to the Tor Browser case works again and the work
around for others is to either symlink the libevent.a at the root or use a
temporary make install directory.
One long term fix here would likely be to ask libevent to symblink the .a into
the root along the .la files and likely do the same for .so. Or, use the
"lib/" structure to contain the .a + .so files. Would be better than doing
ninji-tsu in our configure.ac

The "-static" compile flag was set globally which means that all autoconf test
were attempting to be built statically and lead to failures of detecting
OpenSSL libraries and others.
This commit adds this flag only to the "tor" binary build.
There is also a fix on where to find libevent.a since it is using libtool, it
is in .libs/.
At this commit, there are still warnings being emitted that informs the user
that the built binary must still be linked dynamically with glibc.

This changes the behaviour of `tor --version` in such a way.
```console
src/app/tor --version
Tor version 0.4.5.1-alpha-dev (git-46ccde66a97d7985).
Tor is running on Linux with Libevent 2.1.12-stable, OpenSSL 1.1.1h, Zlib 1.2.11, Liblzma 5.2.4, Libzstd 1.4.5 and Glibc 2.31 as libc.
Tor compiled with GCC version 10.2.0
```

Typos found with codespell.
Please keep in mind that this should have impact on actual code
and must be carefully evaluated:
src/core/or/lttng_circuit.inc
- ctf_enum_value("CONTROLER", CIRCUIT_PURPOSE_CONTROLLER)
+ ctf_enum_value("CONTROLLER", CIRCUIT_PURPOSE_CONTROLLER)
It turns out that STAP_PROBEV() is not available on FreeBSD thus having
sdt/sdt.h is not enough. Look for it now at configure time.

We can't do this in the C headers, since by the time we include
`opensslv.h` in order to check the openssl version number, we will
have included `openssl/macros.h`, which is the thing that checks
whether we disabled deprecation warnings.
We don't look at the patchlevel, since that tends not to have any
API changes, and sometimes gets out of sync when distributors are
careless.
We only give the warning when the test program compiles but gives a
nonzero exit status: sadly, autoconf doesn't give us an easy way to
distinguish these.

This patch disables the glob() support in the path library if glob() is
unavailable at build-time. This currently happens with the Android NDK
used for Tor Browser.

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.
