dc7aa98b76 all: use set.Set consistently instead of map[T]struct{}
I didn't clean up the more idiomatic map[T]bool with true values, at
least yet.  I just converted the relatively awkward struct{}-valued
maps.

0909e90890 util/lru: replace container/list with a custom ring implementation
pre-generics container/list is quite unpleasant to use, and the pointer
manipulation operations for an LRU are simple enough to implement directly
now that we have generic types.

With this change, the LRU uses a ring (aka circularly linked list) rather
than a simple doubly-linked list as its internals, because the ring makes
list manipulation edge cases more regular: the only remaining edge case is
the transition between 0 and 1 elements, rather than also having to deal
specially with manipulating the first and last members of the list.

While the primary purpose was improved readability of the code, as it
turns out removing the indirection through an interface box also speeds
up the LRU:

       │ before.txt  │              after.txt              │
       │   sec/op    │   sec/op     vs base                │
LRU-32   67.05n ± 2%   59.73n ± 2%  -10.90% (p=0.000 n=20)

cmd/tailscale: Check App Store tailscaled dialable before selecting. (#9234)
PR #9217 attempted to fix the same issue, but suffered from not letting the
user connect to non-oss tailscaled if something was listening on the socket, as
the --socket flag doesn't let you select the mac apps.

Rather than leave the user unable to choose, we keep the mac/socket preference
order the same and check a bit harder whether the macsys version really is
running. Now, we prefer the App Store Tailscale (even if it's Stopped) and you
can use --socket to sswitch. But if you quit the App Store Tailscale, we'll try
the socket without needing the flag.

7d60c19d7d clientupdate/distsign: add ability to validate a binary that is already located on disk
Our build system caches files locally and only updates them when something
changes. Since I need to integrate some distsign stuff into the build system
to validate our Windows 7 MSIs, I want to be able to check the cached copy
of a package before downloading a fresh copy from pkgs.

If the signature changes, then obviously the local copy is outdated and we
return an error, at which point we call Download to refresh the package.

resetControlClientLocked is called while b.mu was held and

to drain.
However, there may be active callbacks from cc already waiting for
b.mu resulting in a deadlock.

This makes it so that resetControlClientLocked does not call
Shutdown, and instead just returns the value.
It also makes it so that any status received from previous cc
are ignored.
