Merges !2

Since the original flags are not taken into account when peeking, the peek
recvmsg call will hang forever in certain circumstances, including in all QT
applications running Wayland. This fix simply adds the original flags, so that
the peeking recvmsg call might be nonblocking, if the original call was
nonblocking.

It gets really noisy with mutt. Not sure why, I expect maybe multi
thread/process makes it that everytime it dies, we get that log statement.

Whatever we use IPv4 or IPv6, make torsocks use the configured SocksPort in
the configuration.

The other IP doesn't work anymore and I can't recall what it was ;).

Because of the SafeSocks parameter of Tor, if set, we can't pass a raw IP
address to Tor since it will believe we did a DNS resolution from the
application.

Now, thanks to #22461, Tor safely accepts an IPv4/IPv6 address withing a FQDN
connect request which avoids the SafeSocks warnings.

The #22461 wasn't backported which means that torsocks working with SafeSocks
is only possible in tor >= 0.3.2 stable series.

Enough things use this now, that the syscall(2) wrapper should support
it, since glibc doesn't provide a wrapper for it, and the documentation
says to invoke it using syscall(2).

Also, replace spaces for a tab.

With this check, we can skip tests that need a running tor when none is
present.

Also update the maatuska hostname for the DNS test.

The ht.h generated functions are now flagged with ATTR_UNUSED so the
compiler knows to ignore the warnings if unused.

Remove -fno-strict-overflow as well. Not needed for gcc and clang
doesn't have it.

On a filesystem not supporting capabilities, an error is thrown out on
stderr which is undesirable and confusing for the user.

This commit throws stderr to /dev/null. The point of this getcap is to
actually see if any capabilities are enabled or none. In the context of
an error, there are none.
