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

Brad Fitzpatrick da8def8e13 all: remove old +build tags
The //go:build syntax was introduced in Go 1.17:

https://go.dev/doc/go1.17#build-lines

gofmt has kept the +build and go:build lines in sync since
then, but enough time has passed. Time to remove them.

Done with:

    perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build')

Josh Bleecher Snyder 6da6d47a83 all: simplify build tags involving iOS
Prior to Go 1.16, iOS used GOOS=darwin,
so we had to distinguish macOS from iOS during GOARCH.

We now require Go 1.16 in our go.mod, so we can simplify.

Josh Bleecher Snyder a4e19f2233 version: remove rsc.io/goversion dependency
rsc.io/goversion is really expensive.
Running version.ReadExe on tailscaled on darwin
allocates 47k objects, almost 11mb.

All we want is the module info. For that, all we need to do
is scan through the binary looking for the magic start/end strings
and then grab the bytes in between them.

We can do that easily and quickly with nothing but a 64k buffer.

moncho e101d8396d portlist, version: update build tags for Go 1.16, Apple M1
Build tags have been updated to build native Apple M1 binaries, existing build
tags for ios have been changed from darwin,arm64 to ios,arm64.

With this change, running go build cmd/tailscale{,d}/tailscale{,d}.go on an Apple
machine with the new processor works and resulting binaries show the expected
architecture, e.g. tailscale: Mach-O 64-bit executable arm64.

Tested using go version go1.16beta1 darwin/arm64.

Updates #943

Brad Fitzpatrick 2072dcc127 version: revert the filepath change from earlier commit
f81233524f changed a use of package 'path' to 'filepath'.
Restore it back to 'path', with a comment.

Also, use the os.Executable-based fallback name in the case where the
binary itself doesn't have Go module information. That was overlooked in
the original code.

Avery Pennarun f81233524f version/cmdname: s/path/filepath/ and fix version.ReadExe() fallback.
We were using the Go 'path' module, which apparently doesn't handle
backslashes correctly. path/filepath does.

However, the main bug turned out to be that we were not calling .Base()
on the path if version.ReadExe() fails, which it seems to do at least
on Windows 7. As a result, our logfile persistence was not working on
Windows, and logids would be regenerated on every restart.

Affects: #620
