f580f4484f tka: move disablement logic out-of-band from AUMs
It doesn't make a ton of sense for disablement to be communicated as an AUM, because
any failure in the AUM or chain mechanism will mean disablement wont function.

Instead, tracking of the disablement secrets remains inside the state machine, but
actual disablement and communication of the disablement secret is done by the caller.

7a5cf39d0d ipn/ipnlocal: fix Taildrop not returning any sharing targets
The CapabilityFileSharingTarget capability added by eb32847d85
is meant to control the ability to share with nodes not owned by the
current user, not to restrict all sharing (the coordination server is
not currently populating the capability at all)

1a093ef482 cmd/tsconnect: extract NPM package for reusing in other projects
`src/` is broken up into several subdirectories:
- `lib/` and `types`/ for shared code and type definitions (more code
  will be moved here)
- `app/` for the existing Preact-app
- `pkg/` for the new NPM package

A new `build-pkg` esbuild-based command is added to generate the files
for the NPM package. To generate type definitions (something that esbuild
does not do), we set up `dts-bundle-generator`.

Includes additional cleanups to the Wasm type definitions (we switch to
string literals for enums, since exported const enums are hard to use
via packages).

Also allows the control URL to be set a runtime (in addition to the
current build option), so that we don't have to rebuild the package
for dev vs. prod use.

b3cc719add cmd/nginx-auth: allow use of shared nodes
When sharing nodes, the name of the sharee node is not exposed (instead
it is hardcoded to "device-of-shared-to-user"), which means that we
can't determine the tailnet of that node.  Don't immediately fail when
that happens, since it only matters if "Expected-Tailnet" is used.

util/deephash: expand fast-path capabilities (#5404)
Add support for maps and interfaces to the fast path.
Add cycle-detection to the pointer handling logic.
This logic is mostly copied from the slow path.

A future commit will delete the slow path once
the fast path never falls back to the slow path.

Performance:

	name                 old time/op    new time/op    delta
	Hash-24                18.5µs ± 1%    14.9µs ± 2%  -19.52%  (p=0.000 n=10+10)
	HashPacketFilter-24    2.54µs ± 1%    2.60µs ± 1%   +2.19%  (p=0.000 n=10+10)
	HashMapAcyclic-24      31.6µs ± 1%    30.5µs ± 1%   -3.42%  (p=0.000 n=9+8)
	TailcfgNode-24         1.44µs ± 2%    1.43µs ± 1%     ~     (p=0.171 n=10+10)
	HashArray-24            324ns ± 1%     324ns ± 2%     ~     (p=0.425 n=9+9)

The additional cycle detection logic doesn't incur much slow down
since it only activates if a type is recursive, which does not apply
for any of the types that we care about.

There is a notable performance boost since we switch from the fath path
to the slow path less often. Most notably, a struct with a field that
could not be handled by the fast path would previously cause
the entire struct to go through the slow path.

78b90c3685 cmd/tsconnect: stop writing build artifacts into src/
We can't write to src/ when tsconnect is used a dependency in another
repo (see also b763a12331). We therefore
need to switch from writing to src/ to using esbuild plugins to handle
the requests for wasm_exec.js (the Go JS runtime for Wasm) and the
Wasm build of the Go module.

This has the benefit of allowing Go/Wasm changes to be picked up without
restarting the server when in dev mode (Go compilation is fast enough
that we can do this on every request, CSS compilation continues to be
the long pole).

util/deephash: specialize for netip.Addr and drop AppendTo support (#5402)
There are 5 types that we care about that implement AppendTo:

	key.DiscoPublic
	key.NodePublic
	netip.Prefix
	netipx.IPRange
	netip.Addr

The key types are thin wrappers around [32]byte and are memory hashable.
The netip.Prefix and netipx.IPRange types are thin wrappers over netip.Addr
and are hashable by default if netip.Addr is hashable.
The netip.Addr type is the only one with a complex structure where
the default behavior of deephash does not hash it correctly due to the presence
of the intern.Value type.

Drop support for AppendTo and instead add specialized hashing for netip.Addr
that would be semantically equivalent to == on the netip.Addr values.

The AppendTo support was already broken prior to this change.
It was fully removed (intentionally or not) in #4870.
It was partially restored in #4858 for the fast path,
but still broken in the slow path.
Just drop support for it altogether.

This does mean we lack any ability for types to self-hash themselves.
In the future we can add support for types that implement:

	interface { DeepHash() Sum }

Test and fuzz cases were added for the relevant types that
used to rely on the AppendTo method.
FuzzAddr has been executed on 1 billion samples without issues.

util/deephash: use sha256x (#5339)
Switch deephash to use sha256x.Hash.

We add sha256x.HashString to efficiently hash a string.
It uses unsafe under the hood to convert a string to a []byte.
We also modify sha256x.Hash to export the underlying hash.Hash
for testing purposes so that we can intercept all hash.Hash calls.

Performance:

	name                 old time/op    new time/op    delta
	Hash-24                19.8µs ± 1%    19.2µs ± 1%  -3.01%  (p=0.000 n=10+10)
	HashPacketFilter-24    2.61µs ± 0%    2.53µs ± 1%  -3.01%  (p=0.000 n=8+10)
	HashMapAcyclic-24      31.3µs ± 1%    29.8µs ± 0%  -4.80%  (p=0.000 n=10+9)

The performance gains is not as dramatic as sha256x over sha256 due to:
1. most of the hashing already occurring through the direct memory hashing logic, and
2. what does not go through direct memory hashing is slowed down by reflect.
