Sonia Appasamy 73bbf941f8 client/web: hook up auth flow
Connects serveTailscaleAuth to the localapi webclient endpoint
and pipes auth URLs and session cookies back to the browser to
redirect users from the frontend.

All behind debug flags for now.

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.

ipn: fix localapi and peerapi protocol for taildrop resume (#9860)
Minor fixes:
* The branch for listing or hashing partial files was inverted.
* The host for peerapi call needs to be real (rather than bogus).
* Handle remote peers that don't support resuming.
* Make resume failures non-fatal (since we can still continue).

This was tested locally, end-to-end system test is future work.

Maisem Ali 24f322bc43 ipn/ipnlocal: do unexpired cert renewals in the background
We were eagerly doing a synchronous renewal of the cert while
trying to serve traffic. Instead of that, just do the cert
renewal in the background and continue serving traffic as long
as the cert is still valid.

This regressed in c1ecae13ab when
we introduced ARI support and were trying to make the experience
of `tailscale cert` better. However, that ended up regressing
the experience for tsnet as it would not always doing the renewal
synchronously.

Brad Fitzpatrick 70de16bda7 ipn/localapi: make whois take IP or IP:port as documented, fix capmap netstack lookup
The whois handler was documented as taking IP (e.g. 100.101.102.103)
or IP:port (e.g. usermode 127.0.0.1:1234) but that got broken at some point
and we started requiring a port always. Fix that.

Also, found in the process of adding tests: fix the CapMap lookup in
userspace mode (it was always returning the caps of 127.0.0.1 in
userspace mode). Fix and test that too.

Whoops.

The fix in ipn/ipnlocal (where it makes a new controlclient) but to

a new "tailscale debug control-knobs" which by itself might be useful
for future debugging.

ipn/{ipnlocal,localapi}: actually renew certs before expiry (#8731)
While our `shouldStartDomainRenewal` check is correct, `getCertPEM`
would always bail if the existing cert is not expired. Add the same
`shouldStartDomainRenewal` check to `getCertPEM` to make it proceed with
renewal when existing certs are still valid but should be renewed.

The extra check is expensive (ARI request towards LetsEncrypt), so cache
the last check result for 1hr to not degrade `tailscale serve`
performance.

Also, asynchronous renewal is great for `tailscale serve` but confusing
for `tailscale cert`. Add an explicit flag to `GetCertPEM` to force a
synchronous renewal for `tailscale cert`.

Mihai Parparita 7330aa593e all: avoid repeated default interface lookups
On some platforms (notably macOS and iOS) we look up the default
interface to bind outgoing connections to. This is both duplicated
work and results in logspam when the default interface is not available
(i.e. when a phone has no connectivity, we log an error and thus cause
more things that we will try to upload and fail).

Fixed by passing around a netmon.Monitor to more places, so that we can
use its cached interface state.
