aa45e82593 Pull up more data when parsing socks messages
Previously, we only looked at up to 128 bytes.  This is a bad idea
since socks messages can be at least 256+x bytes long.  Now we look at
up to 512 bytes; this should be enough for 0.2.2.x to handle all valid
SOCKS messages.  For 0.2.3.x, we can think about handling trickier
cases.

Fixes 2330.  Bugfix on 0.2.0.16-alpha.

bd67b23fec Always nul-terminate the result passed to evdns_server_add_ptr_reply
In dnsserv_resolved(), we carefully made a nul-terminated copy of the
answer in a PTR RESOLVED cell... then never used that nul-terminated
copy.  Ouch.

Surprisingly this one isn't as huge a security problem as it could be.
The only place where the input to dnsserv_resolved wasn't necessarily
nul-terminated was when it was called indirectly from relay.c with the
contents of a relay cell's payload.  If the end of the payload was
filled with junk, eventdns.c would take the strdup() of the name [This
part is bad; we might crash there if the cell is in a bad part of the
stack or the heap] and get a name of at least length
495[*]. eventdns.c then rejects any name of length over 255, so the
bogus data would be neither transmitted nor altered.

  [*] If the name was less than 495 bytes long, the client wouldn't
     actually be reading off the end of the cell.

Nonetheless this is a reasonably annoying bug.  Better fix it.

Found while looking at bug 2332, reported by doorss.  Bugfix on
0.2.0.1-alpha.

373a1bc40e Impose maximum sizes on parsed objects
An object, you'll recall, is something between -----BEGIN----- and
-----END----- tags in a directory document.  Some of our code, as
doorss has noted in bug 2352, could assert if one of these ever
overflowed SIZE_T_CEILING but not INT_MAX.  As a solution, I'm setting
a maximum size on a single object such that neither of these limits
will ever be hit.  I'm also fixing the INT_MAX checks, just to be sure.

68d5b6bc52 Fix check for failed evdns request creation
When using libevent 2, we use evdns_base_resolve_*().  When not, we
fake evdns_base_resolve_*() using evdns_resolve_*().

Our old check was looking for negative values (like libevent 2
returns), but our eventdns.c code returns 1.  This code makes the
check just test for nonzero.

Note that this broken check was not for _resolve_ failures or even for
failures to _launch_ a resolve: it was for failures to _create_ or
_encode_ a resolve request.

Bug introduced in 81eee0ecfff3dac1e9438719d2f7dc0ba7e84a71; found by
lodger; uploaded to trac by rransom.  Bug 2363.  Fix on 0.2.2.6-alpha.

2008728df7 Notice a little faster if we're running out of virtual addresses
We were not decrementing "available" every time we did
++next_virtual_addr in addressmap_get_virtual_address: we left out the
--available when we skipped .00 and .255 addresses.

This didn't actually cause a bug in most cases, since the failure mode
was to keep looping around the virtual addresses until we found one,
or until available hit zero.  It could have given you an infinite loop
rather than a useful message, however, if you said "VirtualAddrNetwork
127.0.0.255/32" or something broken like that.

31d6659d97 Fix a double-counting bug in addrmap_get_virtual_address
We were decrementing "available" twice for each in-use address we ran
across.  This would make us declare that we ran out of virtual
addresses when the address space was only half full.

5c09431cc7 Never include pthread.h when building for Windows.
On Windows, we never use pthreads, since it doesn't usually exist,
and when it does it tends to be a little weirdly-behaved.  But some
mingw installations have a pthreads installed, so autoconf detects
pthread.h and tells us about it.  This would make us include
pthread.h, which could make for trouble when the iffy pthread.h
tried to include config.h.

This patch changes compat.h so that we never include pthread.h on
Windows.  Fixes bug 2313; bugfix on 0.1.0.1-rc.
