This commit is completely mechanical; I used this perl script to make it:

 if (/^\s*\#/) {
     s/MS_WINDOWS/_WIN32/g;
     s/\bWIN32\b/_WIN32/g;

9c29369a04 Convert instances of tor_malloc+tor_snprintf into tor_asprintf
These were found by looking for tor_snprintf() instances that were
preceeded closely by tor_malloc(), though I probably converted some
more snprintfs as well.

(In every case, make sure that the length variable (if any) is
removed, renamed, or lowered, so that anything else that might have
assumed a longer buffer doesn't exist.)

04c622d720 Add some post-comma spaces to please arma
Incidentally, we've got 30969 lines in master with a comma
in them, of which 1995 have a comma followed by a non-newline,
non-space character.  So about 93% of our commas are right,
but we have a substantial number of "crowded" lines.

69d16900aa Refactor addressmap_match_superdomains and representation of wildcards
In this new representation for wildcarded addresses, there are no
longer any 'magic addresses': rather, "a.b c.d", "*.a.b c.d" and
"*.a.b *.c.d" are all represented by a mapping from "a.b" to "c.d". we
now distinguish them by setting bits in the addressmap_entry_t
structure, where src_wildcard is set if the source address had a
wildcard, and dst_wildcard is set if the target address had a
wildcard.

This lets the case where "*.a.b *.c.d" or "*.a.b c.d" remap the
address "a.b" get handled trivially, and lets us simplify and improve
the addressmap_match_superdomains implementation: we can now have it
run in O(parts of address) rather than O(entries in addressmap).

f786307ab7 First chunk of support for bridges on IPv6
Comments below focus on changes, see diff for added code.

New type tor_addr_port_t holding an IP address and a TCP/UDP port.

New flag in routerinfo_t, ipv6_preferred.  This should go in the
node_t instead but not now.

Replace node_get_addr() with
- node_get_prim_addr() for primary address, i.e. IPv4 for now
- node_get_pref_addr() for preferred address, IPv4 or IPv6.

Rename node_get_addr_ipv4h() node_get_prim_addr_ipv4h() for
consistency.  The primary address will not allways be an IPv4 address.
Same for node_get_orport() -> node_get_prim_orport().

Rewrite node_is_a_configured_bridge() to take all OR ports into account.

Extend argument list to extend_info_from_node and
extend_info_from_router with a flag indicating if we want to use the
routers primary address or the preferred address.  Use the preferred
address in as few situtations as possible for allowing clients to
connect to bridges over IPv6.

230422b955 Support for a defaults torrc file.
This will mainly help distributors by giving a way to set system or package
defaults that a user can override, and that a later package can replace.

No promises about the particular future location or semantics for this:
we will probably want to tweak it some before 0.2.3.x-rc

The file is searched for in CONFDIR/torrc-defaults , which can be
overridden with the "--defaults-torrc" option on the command line.

393e4fb5b5 Use %f with printf-style formatting, not %lf
For printf, %f and %lf are synonymous, since floats are promoted to
doubles when passed as varargs.  It's only for scanf that we need to
say "%lf" for doubles and "%f" for floats.

Apparenly, some older compilers think it's naughty to say %lf and like
to spew warnings about it.

e617a34d58 Add, use a bufferevent-safe connection_flush()
A couple of places in control.c were using connection_handle_write()
to flush important stuff (the response to a SIGNAL command, an
ERR-level status event) before Tor went down.  But
connection_handle_write() isn't meaningful for bufferevents, so we'd
crash.

This patch adds a new connection_flush() that works for all connection
backends, and makes control.c use that instead.

Fix for bug 3367; bugfix on 0.2.3.1-alpha.

a5232e0c4c Fix GCC 4.6's new -Wunused-but-set-variable warnings.
Most instances were dead code; for those, I removed the assignments.
Some were pieces of info we don't currently plan to use, but which
we might in the future.  For those, I added an explicit cast-to-void
to indicate that we know that the thing's unused.  Finally, one was
a case where we were testing the wrong variable in a unit test.
That one I fixed.

This resolves bug 3208.

cfeafe5e77 Use a 64-bit type to hold sockets on win64.
On win64, sockets are of type UINT_PTR; on win32 they're u_int;
elsewhere they're int.  The correct windows way to check a socket for
being set is to compare it with INVALID_SOCKET; elsewhere you see if
it is negative.

On Libevent 2, all callbacks take sockets as evutil_socket_t; we've
been passing them int.

This patch should fix compilation and correctness when built for
64-bit windows.  Fixes bug 3270.

59f9097d5c Hand-conversion and audit phase of memcmp transition
Here I looked at the results of the automated conversion and cleaned
them up as follows:

   If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
   changed it to a fast_memcmp or fast_memeq.

   Otherwise if there was a tor_memcmp that could turn into a
   tor_memneq or tor_memeq, I converted it.

This wants close attention.

[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.

58a16a4d6f Add an assert to un-confuse clang's analyzer
The analyzer assumed that bootstrap_percent could be less than 0 when we
call control_event_bootstrap_problem(), which would mean we're calling
log_fn() with undefined values. The assert makes it clear this can't
happen.

f810a1afe9 Expose a new process_signal(uintptr_t), not signal_callback()
This is a tweak to the bug2917 fix.  Basically, if we want to simulate
a signal arriving in the controller, we shouldn't have to pretend that
we're Libevent, or depend on how Tor sets up its Libevent callbacks.

control_signal_act().

Fixes bug 2917, reported by Robert Ransom. Bugfix on commit

a patch by Robert (Changelog entry).
