a2f0e7a65b Cut down on the OS information we give.
For uname-based detection, we now give only the OS name (e.g.,
"Darwin", "Linux".)  For Windows, we give only the Operating System
name as inferred from dw(Major|Minor)version, (e.g., "Windows XP",
"Windows 7"), and whether the VER_NT_SERVER flag is set.

For ticket 2988.

35d08e30d8 An attempt at bug3940 and making AllowDotExit 0 work with MapAddress
This time, I follow grarpamp's suggestion and move the check for
.exit+AllowDotExit 0 to the top of connection_ap_rewrite_and_attach,
before any rewriting occurs.  This way, .exit addresses are
forbidden as they arrive from a socks connection or a DNSPort
request, and not otherwise.

It _is_ a little more complicated than that, though.  We need to
treat any .exit addresses whose source is TrackHostExits as meaning
that we can retry without that exit.  We also need to treat any
.exit address that comes from an AutomapHostsOnResolve operation as
user-provided (and thus forbidden if AllowDotExits==0), so that
transitioning from AllowDotExits==1 to AllowDotExits==0 will
actually turn off automapped .exit addresses.

e6dbe693b7 Make the option-checker code work with osx clang
This is a matter of making gcc and friends squirm more loudly when
they get an option they don't like (-pedantic) and making clang shut
up with it gets an option it tolerates but doesnt know
(-Qunknown-argument).

Is there no better way?

e36cd01633 Try to manually test for whether the compiler hardening flags work
Also, make the check for whether they're on by default work; there's
no need to mess around with this "$enableval" silliness.

6757261e8f Raise thresholds for declaring bootstrapping complete.
This patch changes the total serverdesc threshold from 25% to 75%
and the exit threshold from 33% to 50%.  The goal is to make
initially constructed circuits less horrible, and to make initial
less awful (since fetching directory information in parallel with
whatever the user is trying to do can hurt their performance).

Implements ticket 3196.

02a650786b Fix O(n^2) performance when parsing a big pile of extrainfos
We were doing an O(n) strlen in router_get_extrainfo_hash() for
every one we tried to parse.  Instead, have
router_get_extrainfo_hash() take the length of the extrainfo as an
argument, so that when it's called from
extrainfo_parse_from_string(), it doesn't do a strlen() over the
whole pile of extrainfos.

9b344628ed Handle out-of-range values in tor_parse_* integer functions
The underlying strtoX functions handle overflow by saturating and
setting errno to ERANGE.  If the min/max arguments to the
tor_parse_* functions are equal to the minimum/maximum of the
underlying type, then with the old approach, we wouldn't treat a
too-large value as genuinely broken.

Found this while looking at bug 5786; bugfix on 19da1f36 (in Tor
0.0.9), which introduced these functions.

66dbbc2960 Apply a patch from Gisle Vanem to make tor-gencert build under MSVC
(Note: It makes sense to use tor-gencert on Windows for testing
purposes only.  If you are a directory authority operator, and you
are contemplating running tor-gencert on a Windows box in an actual
production environment, you are probably making a mistake.)

We had been checking for EINVAL, but that means that SOCK_* isn't
supported, not that the syscall itself is missing.

6b4af10716 Ignore [::] when building descriptors.
This is how IPv6 says "0.0.0.0" and something we will have to
translate into a globally reachable address before putting it in a
descriptor.

The fix is a short term solution until a real one is implemented.

Closes #5146.

c03a233faa Remove __ from HAVE_EXTERN_ENVIRON_DECLARED__
I think that the trailing __ got added in false analogy to
HAVE_MACRO__func__, HAVE_MACRO__FUNC__, and HAVE_MACRO__FUNCTION__.
But those macros actually indicate the presence of __func__,
__FUNC__, and __FUNCTION__ respectively.  The __ at the end of
HAVE_EXTERN_ENVIRON_DECLARED would only be appropriate if the
environ were declared__, whatever that means.

(As a side-note, HAVE_MACRO__func__ and so on should probably be
renamed HAVE_MACRO___func__ and so on.  But that can wait.)

This is an identifier renaming only.

6156403237 Fix headers in test for whether environ is declared in stdlib/unistd
We'd had our configure.in test include unistd.h unconditionally,

Thanks to Erinn for finding this and rransom for figuring out the

f0212197cc Only disable cert chaining on the first TLS handshake
If the client uses a v2 cipherlist on the renegotiation handshake,
it looks as if they could fail to get a good cert chain from the
server, since they server would re-disable certificate chaining.

This patch makes it so the code that make the server side of the
first v2 handshake special can get called only once.
