If we get an address suggestion from a directory authority and we have no
address configured or discovered, log it at notice level so the operator can
learn what address will be used by Tor.

The previous parser only considered stats files _starting_ with the
timestamp tag, not stats files having the timestamp tag in a later
position. While this applies to all current stats files, a future
stats file might look differently. Better to fix the function now than
be surprised in another 9 years from now.

This commit also adds a test case for such future stats, and it fixes
stats file paths in newly added unit tests.

It turns out that 9 years ago, we stopped appending data into stats file and
rather overwrite everytime we have new stats (see commit
a6a127c8)

The load_stats_file() function was still thinking that we could have the same
line many times in the file which turns out to be false since 9 years ago.
However, that did not cause problem until IPv6 connection stats came along
which introduced a new line in conn-stats: "ipv6-conn-bi-direct ...".

Before, that file contained a single line starting with the tag
"conn-bi-direct".  That very tag appears also in the IPv6 tag (see above) so
the load_stats_file() function would consider that the IPv6 line as the last
tag to be appeneded to the file and fail to report the line above (for IPv4).
It would actually truncate the IPv6 line and report it (removing the "ipv6-"
part).

In other words, "conn-bi-direct" was not reported and instead
"ipv6-conn-bi-direct" was used without the "ipv6-" part.

This commit refactors the entire function so that now it looks for a
"timestamp tag" to validate and then if everything is fine, returns the entire
content of the file. The refactor simplifies the function, adds logging in
case of failures and modernize it in terms of coding standard.

Unit tests are also added that makes sure the loaded content matches the
entire file if timestamp validation passes.

When making sure we have a Bridge line with a ClientTransportPlugin, we
now check in the managed proxy list and so we can catch any missing
ClientTransportPlugin for a Bridge line.

Previously, our code would send back an error if the socks5 request
parser said anything but DONE.  But there are other non-error cases,
like TRUNCATED: we shouldn't send back errors for them.

This patch lowers the responsibility for setting the error message
into the parsing code, since the actual type of the error message
will depend on what problem was encountered.

Fixes bug 40190; bugfix on 0.3.5.1-alpha.

From c618c4f2, 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
