Brad Fitzpatrick 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.

Updates #cleanup

Joe Tsai c6fadd6d71
all: implement AppendText alongside MarshalText (#9207)
This eventually allows encoding packages that may respect
the proposed encoding.TextAppender interface.
The performance gains from this is between 10-30%.

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

Tom DNetto 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.

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 f50043f6cb tka,types/key: remove dependency for tailcfg & types/ packages on tka
Following the pattern elsewhere, we create a new tka-specific types package for the types
that need to couple between the serialized structure types, and tka.

Tom DNetto 1cfd96cdc2 tka: implement AUM and Key types
This is the first in a series of PRs implementing the internals for the
Tailnet Key Authority. This PR implements the AUM and Key types, which
are used by pretty much everything else. Future PRs:

 - The State type & related machinery
 - The Tailchonk (storage) type & implementation
 - The Authority type and sync implementation
