This patch fixes a memory leak in new_establish_intro_cell() that could
happen if a test assertion fails and the *cell_out value isn't properly
free'd.

This patch fixes a memory leak in pick_hsdir_v3() where we might return
early, but forgot to free the responsible_hsdirs variable. We solve this
by not allocating storage for responsible_hsdirs until it's actually
needed.

There are a few reasons that relays might be uploading desciptors
without saying X-Desc-Gen-Reason:
1. They are running an old version of our software, before 0.3.2.stable.
2. They are not running our software, but they are claiming they
are.
3. They are uploading through a proxy that strips X-Desc-Gen-Reason.
4. They somehow had a bug in their software.
According to the 25686 data, 1 is the most common reason. This
ticket is an attempt to diagnose case 4, or prove that case 4
doesn't actually happen.
The specification describes the signature token to be right after a newline
(\n) then the token "signature" and then a white-space followed by the encoded
signature.
This commit makes sure that when we parse the signature from the descriptor,
we are always looking for that extra white-space at the end of the token.
It will allow us also to support future fields that might start with
"signature".

The any_client_port_set() returns true if the ControlPort is set which is
wrong because we can have that port open but still not behave as a tor client
(like many relays for instance).

When directory authorities read a zero-byte bandwidth file, they log
a warning with the contents of an uninitialised buffer. Log a warning
about the empty file instead.
Fixes bug 26007; bugfix on 0.2.2.1-alpha.
