Will Norris 71029cea2d all: update copyright and license headers
This updates all source files to use a new standard header for copyright
and license declaration.  Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

Updates #6865

Eng Zer Jun f0347e841f refactor: move from io/ioutil to io and os packages

David Crawshaw 15b8665787 tka: stable text representation of AUMHash
This makes debugging easier, you can pass an AUMHash to a printf and get
a string that is easy to debug.

Also rearrange how directories/files work in the FS store: use the first
two characters of the string representation as the prefix directory, and
use the entire AUMHash string as the file name. This is again to aid
debugging: you can `ls` a directory and line up what prints out easily
with what you get from a printf in debug code.

Tom DNetto 4001d0bf25 assorted: plumb tka initialization & network-lock key into tailscaled
- A network-lock key is generated if it doesn't already exist, and stored in the StateStore. The public component is communicated to control during registration.
 - If TKA state exists on the filesystem, a tailnet key authority is initialized (but nothing is done with it for now).

Tom DNetto ec4f849079 tka: implement filesystem-based tailchonk implementation
FS implements Chonk, and given the expected load characteristics (frequent use
of AUM() + ChildAUMs(), and infrequent use of Heads() + CommitVerifiedAUMs()), the
implementation avoids scanning the filesystem to service AUM() and ChildAUMs().

Tom DNetto cca25f6107 tka: implement Chonk type & an in-memory implementation
Chonks are responsible for efficient storage of AUMs and other TKA state.

For testing/prototyping I've implemented an in-memory version, but once we
start to use this from tailscaled we'll need a file-based version.
