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

 #!/usr/bin/perl -w -i.bak -p

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

d5e964731c Fixed build with GCC < 3.3
Preprocessor directives should not be put inside the arguments
of a macro. This is not supported on older GCC releases (< 3.3)
thus broke compilation on Haiku (running gcc2).

5f0a8dcd2c Initial hacking for proposal 186.
This code handles the new ORPort options, and incidentally makes all
remaining port types use the new port configuration systems.

There are some rough edges!  It doesn't do well in the case where your
Address says one thing but you say to Advertise another ORPort.  It
doesn't handle AllAddrs.  It doesn't actually advertise anything besides
the first listed advertised IPv4 ORPort and DirPort.  It doesn't do
port forwarding to them either.

It's not tested either, it needs more documentation, and it probably
forgets to put the milk back in the refrigerator.

df9b76460c New 'DisableNetwork' option to prevent Tor from using the network
Some controllers want this so they can mess with Tor's configuration
for a while via the control port before actually letting Tor out of
the house.

We do this with a new DisableNetwork option, that prevents Tor from
making any outbound connections or binding any non-control
listeners.  Additionally, it shuts down the same functionality as
shuts down when we are hibernating, plus the code that launches
directory downloads.

To make sure I didn't miss anything, I added a clause straight to
connection_connect, so that we won't even try to open an outbound
socket when the network is disabled.  In my testing, I made this an
assert, but since I probably missed something, I've turned it into a
BUG warning for testing.

e3cee8bc2e Simply initialize TLS context if DynamicDHGroups change.
We used to do init_keys() if DynamicDHGroups changed after a HUP, so
that the dynamic DH modulus was stored on the disk. Since we are now
doing dynamic DH modulus storing in crypto.c, we can simply initialize
the TLS context and be good with it.

Introduce a new function router_initialize_tls_context() which
initializes the TLS context and use it appropriately.

6e6a661296 New UserspaceIOCPBuffers option to set SO_{SND,RCV}BUF to zero
When running with IOCP, we are in theory able to use userspace-
allocated buffers to avoid filling up the stingy amount of kernel
space allocated for sockets buffers.

The bufferevent_async implementation in Libevent provides this
ability, in theory.  (There are likely to be remaining bugs).  This
patch adds a new option that, when using IOCP bufferevents, sets
each socket's send and receive buffers to 0, so that we should use
this ability.

When all the bugs are worked out here, if we are right about bug 98,
this might solve or mitigate bug 98.

This option is experimental and will likely require lots of testing
and debugging.

many fetches happen in total.

d0416ce3ec Don't warn of stray Bridges if managed proxies are still unconfigured.
With managed proxies you would always get the error message:

"You have a Bridge line using the X pluggable transport, but there
doesn't seem to be a corresponding ClientTransportPlugin line."

because the check happened directly after parse_client_transport_line()
when managed proxies were not fully configured and their transports
were not registered.

The fix is to move the validation to run_scheduled_events() and make
sure that all managed proxies are configured first.

1f4b6944c0 Upload descriptors more often when recent desc is unlisted
Right now we only force a new descriptor upload every 18 hours.
This can make servers become unlisted if they upload a descriptor at
time T which the authorities reject as being "too similar" to one
they uploaded before. Nothing will actually make the server upload a
new descriptor later on, until another 18 hours have passed.

This patch changes the upload behavior so that the 18 hour interval
applies only when we're listed in a live consensus with a descriptor
published within the last 18 hours.  Otherwise--if we're not listed
in the live consensus, or if we're listed with a publication time
over 18 hours in the past--we upload a new descriptor every 90
minutes.

This is an attempted bugfix for #3327.  If we merge it, it should
obsolete #535.

1d3c8c1f74 Add a new isolation type and field: "nym epoch"
The "nym epoch" of a stream is defined as the number of times that
NEWNYM had been called before the stream was opened.  All streams
are isolated by nym epoch.

This feature should be redundant with existing signewnym stuff, but
it provides a good belt-and-suspenders way for us to avoid ever
letting any circuit type bypass signewnym.
