We used a HandleSet before when we didn't have a unique handle. But a
sessionID is a unique handle, so use that instead. Then that replaces
the other map we had.
And now we'll have a way to look up an IPN session by sessionID for
later.

This fixes a regression introduced with 993acf4 and released in
v1.60.0.
The regression caused us to intercept all userspace traffic to port
8080 which prevented users from exposing their own services to their
tailnet at port 8080.
Now, we only intercept traffic to port 8080 if it's bound for
100.100.100.100 or fd7a:115c:a1e0::53.

This adds a method to wgengine.Engine and plumbed down into magicsock
to add a way to get a type-safe Tailscale-safe wrapper around a

Tailscale to use internally.
It also removes HandshakeAttempts from PeerStatusLite that was just
added as it wasn't needed yet and is now accessible ala cart as needed
from the Peer type accessor.
None of this is used yet.

This server recently had a common ansible applied, which added a
periodic /tmp cleaner, as is needed on other CI machines to deal with
test tempfile leakage. The setting of $HOME to /tmp means that the go
toolchain in there was regularly getting pruned by the tmp cleaner, but
often incompletely, because it was also in use.

Update typescript to 5.3.3. This is a major bump from the previous
version of 4.8.3. This also requires adding newer versions of
@typescript-eslint/eslint-plugin and @typescript-eslint/parser to our
resolutions as eslint-config-react-app pulls in versions that otherwise
do not support typescript 5.x.
eslint-config-react-app has not been updated in 2 years and is seemingly
abandoned, so we may wish to fork it or move to a different eslint config
in the future.

This is a fun one. Right now, when a client is connecting through a
subnet router, here's roughly what happens:
1. The client initiates a connection to an IP address behind a subnet
router, and sends a TCP SYN
2. The subnet router gets the SYN packet from netstack, and after
running through acceptTCP, starts DialContext-ing the destination IP,
without accepting the connection¹
3. The client retransmits the SYN packet a few times while the dial is
in progress, until either...
4. The subnet router successfully establishes a connection to the
destination IP and sends the SYN-ACK back to the client, or...
5. The subnet router times out and sends a RST to the client.
6. If the connection was successful, the client ACKs the SYN-ACK it
received, and traffic starts flowing
As a result, the notification code in forwardTCP never notices when a
new connection attempt is aborted, and it will wait until either the
connection is established, or until the OS-level connection timeout is
reached and it aborts.
To mitigate this, add a per-client limit on how many in-flight TCP
forwarding connections can be in-progress; after this, clients will see
a similar behaviour to the global limit, where new connection attempts
are aborted instead of waiting. This prevents a single misbehaving
client from blocking all other clients of a subnet router by ensuring
that it doesn't starve the global limiter.
Also, bump the global limit again to a higher value.
¹ We can't accept the connection before establishing a connection to the
remote server since otherwise we'd be opening the connection and then
immediately closing it, which breaks a bunch of stuff; see #5503 for
more details.

When reverse path filtering is in strict mode on Linux, using an exit

this to `tailscale status` and the logs.

- The following issues on your machine will likely make usage of exit nodes impossible: [interface "eth0" has strict reverse-path filtering enabled], please set rp_filter=2 instead of rp_filter=1; see https://github.com/tailscale/tailscale/issues/3310

The derper sends an in-protocol keepalive every 60-65s, so frequent TCP
keepalives are unnecessary. In this tuning TCP keepalives should never
occur for a DERP client connection, as they will send an L7 keepalive
often enough to always reset the TCP keepalive timer. If however a
connection does not receive an ACK promptly it will now be shutdown,
which happens sooner than it would with a normal TCP keepalive tuning.
This re-tuning reduces the frequency of network traffic from derp to
client, reducing battery cost.
