Going to reuse Meta instead as that is already exported.

Current code will set the "dirty" field of VersionInfo always "true"
if vcs.modified flag is there. No matter whether the flag is "true" or
"false". It will make sense to set this field due to vcs.modified
value, not only the existence of the key.

Commit 59c254579e moved a lot of work
from functions that could be eliminated at compile time (because
tests against runtime.GOOS are compile-time constant), into code
that must always run before main().
So, revert that, and instead optimize the package only by moving the
remaining string processing code behind sync.Onces.

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.

Add `tailscale version --json` JSON output mode. This will be used
later for a double-opt-in (per node consent like Tailscale SSH +
control config) to let admins do remote upgrades via `tailscale
update` via a c2n call, which would then need to verify the
cmd/tailscale found on disk for running tailscale update corresponds
to the running tailscaled, refusing if anything looks amiss.
Plus JSON output modes are just nice to have, rather than parsing
unstable/fragile/obscure text formats.

Allows a dev built to provide GitCommit and have the short hash
computed correctly, even if the Go embedded build info lacks a
git commit.

(Fix to 31e4f60047)
The 31e4f60047 change accidentally
made it always prepend the VERSION.txt, even when it was already
link-stamped properly.

Updates tailscale/corp#1574
Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
After mapver 5's incremental netmap updates & user profiles, much of
the remaining bandwidth for streamed MapResponses were redundant,
unchanged PacketFilters. So make MapRequest.Version 6 mean that nil
means unchanged from the previous value.
When building with redo, also include the git commit hash
from the proprietary repo, so that we have a precise commit
that identifies all build info (including Go toolchain version).
Add a top-level build script demonstrating to downstream distros
how to burn the right information into builds.
Adjust `tailscale version` to print commit hashes when available.
Fixes#841.
