derp/derphttp: strip port numbers from URL hostname
When trying to set up multiple derper instances meshing with each
other, it turned out that while one can specify an alternative
listening port using the -a flag, the TLS hostname gets incorrectly
determined and includes the set alternative listening port as part of
the hostname. Thus, the TLS hostname validation always fails when the
-mesh-with values have ports.

Brad Fitzpatrick 514539b611 wgengine/magicsock: close disco listeners on Conn.Close, fix Linux root TestNewConn
TestNewConn now passes as root on Linux. It wasn't closing the BPF
listeners and their goroutines.

The code is still a mess of two Close overlapping code paths, but that
can be refactored later. For now, make the two close paths more similar.

clientupdate: distinguish when auto-updates are possible (#9896)
clientupdate.Updater will have a non-nil Update func in a few cases
where it doesn't actually perform an update:
* on Arch-like distros, where it prints instructions on how to update
* on macOS app store version, where it opens the app store page

Add a new clientupdate.Arguments field to cause NewUpdater to fail when
we hit one of these cases. This results in c2n updates being "not
supported" and `tailscale set --auto-update` returning an error.

James Tucker 7df6f8736a wgengine/netstack: only add addresses to correct protocols
Prior to an earlier netstack bump this code used a string conversion
path to cover multiple cases of behavior seemingly checking for
unspecified addresses, adding unspecified addresses to v6. The behavior
is now crashy in netstack, as it is enforcing address length in various
areas of the API, one in particular being address removal.

As netstack is now protocol specific, we must not create invalid
protocol addresses - an address is v4 or v6, and the address value
contained inside must match. If a control path attempts to do something
otherwise it is now logged and skipped rather than incorrect addressing
being added.

clientupdate: manually restart Windows GUI after update (#9906)
When updating via c2n, `tailscale.exe update` runs from `tailscaled.exe`
which runs as SYSTEM. The MSI installer does not start the GUI when
running as SYSTEM. This results in Tailscale just existing on
auto-update, which is ungood.

Instead, always ask the MSI installer to not launch the GUI (via
`TS_NOLAUNCH` argument) and launch it manually with a token from the
current logged in user. The token code was borrowed from
d9081d6ba2/net/dns/wsl_windows.go (L207-L232)

Also, make some logging changes so that these issues are easier to debug

handling:

1. Properly passes back the error code from the noise request from
   the localapi. Previously we were using io.Copy, which was always
   setting a 200 response status code.
2. Clean up web client browser sessions on any /wait endpoint error.
   This avoids the user getting in a stuck state if something goes

taildrop: fix theoretical race condition in fileDeleter.Init (#9876)
It is possible that upon a cold-start, we enqueue a partial file
for deletion that is resumed shortly after startup.

If the file transfer happens to last longer than deleteDelay,
we will delete the partial file, which is unfortunate.
The client spent a long time uploading a file,
only for it to be accidentally deleted.
It's a very rare race, but also a frustrating one
if it happens to manifest.

Fix the code to only delete partial files that
do not have an active puts against it.

We also fix a minor bug in ResumeReader
where we read b[:blockSize] instead of b[:cs.Size].
The former is the fixed size of 64KiB,
while the latter is usually 64KiB,
but may be less for the last block.

cmd/tailscale: improve taildrop progress printer on Linux (#9878)
The progress printer was buggy where it would not print correctly
and some of the truncation logic was faulty.

The progress printer now prints something like:

	go1.21.3.linux-amd64.tar.gz               21.53MiB      13.83MiB/s     33.88%    ETA 00:00:03

where it shows
* the number of bytes transferred so far
* the rate of bytes transferred
  (using a 1-second half-life for an exponentially weighted average)
* the progress made as a percentage
* the estimated time
  (as calculated from the rate of bytes transferred)

Other changes:
* It now correctly prints the progress for very small files
* It prints at a faster rate (4Hz instead of 1Hz)
* It uses IEC units for byte quantities
  (to avoid ambiguities of "kb" being kilobits or kilobytes)

Maisem Ali c3a8e63100 util/linuxfw: add additional nftable detection logic
We were previously using the netlink API to see if there are chains/rules that
already exist. This works fine in environments where there is either full
nftable support or no support at all. However, we have identified certain
environments which have partial nftable support and the only feasible way of
detecting such an environment is to try to create some of the chains that we
need.

This adds a check to create a dummy postrouting chain which is immediately
deleted. The goal of the check is to ensure we are able to use nftables and
that it won't error out later. This check is only done in the path where we
detected that the system has no preexisting nftable rules.

taildrop: switch hashing to be streaming based (#9861)
While the previous logic was correct, it did not perform well.
Resuming is a dance between the client and server, where
1. the client requests hashes for a partial file,
2. the server then computes those hashes,
3. the client computes hashes locally and compares them.
4. goto 1 while the partial file still has data

While step 2 is running, the client is sitting idle.
While step 3 is running, the server is sitting idle.

By streaming over the block hash immediately after the server
computes it, the client can start checking the hash,
while the server works on the next hash (in a pipelined manner).
This performs dramatically better and also uses less memory
as we don't need to hold a list of hashes, but only need to
handle one hash at a time.

There are two detriments to this approach:
* The HTTP API relies on a JSON stream,
  which is not a standard REST-like pattern.
  However, since we implement both client and server,
  this is fine.
* While the stream is on-going, we hold an open file handle
  on the server side while the file is being hashed.
  On really slow streams, this could hold a file open forever.
