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.

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.

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.

The fallthrough happened to work in controlclient already due to the
/etc/os-release PRETTY_NAME default, but make it explicit so it
doesn't look like an accident.
Also add it to version/distro, even though nothing needs it yet.
This is a repeat of commit 3aa68cd397
which was lost in a rework of version.sh.
git worktrees have a .git file rather than a .git directory, so building
in a worktree caused version.sh to generate an error.

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.
Instead of reverting to 0.0.0, keep the same version number (eg. 1.2.4)
but add an extra suffix with the change count,
eg. 1.2.4-6-tb35d95ad7-gcb8be72e6. This avoids the problem where a
small patch causes the code to report a totally different version to
the server, which might change its behaviour based on version code.
(The server might enable various bug workarounds since it thinks
0.0.0 is very old.)

This option isn't available on slightly older versions of git. We were
no longer using the real describe functionality anyway, so let's just do
something simpler to detect a dirty worktree.
While we're here, fix up a little bit of sh style.

This makes it easier to integrate this version math into a submodule-ful
world. We'll continue to have regular git tags that parallel the information
in VERSION, so that builds out of this repository behave the same.

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.

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.
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.

I added them earlier while fighting our redo+xcode build which wasn't
picking up these files on incremental builds. It still isn't, but now I've
verified with full builds that no quotes is correct.
Our primary version format is git describe --long --abbrev=9.
Our Apple scheme is:
(major+100).minor.(patch*10,000+gitDescribeCommits).
This CL gets rid of the third, which was:
major.minor.(patch*10,000+gitDescribeCommits).
Now the "About" box in the macOS app shows the same version that we
show on pkgs.tailscale.com, userz, changelog, etc.
This will be more important once/if we get standalone DMG downloads
for macOS on pkgs.tailscale.com.
Fixestailscale/corp#364
It existed previously to persuade Go that redo-ful directory was
a Go package prior to the first build. But now we have other Go
files in the directory that will fulfil that function.

* remove endpoint discovery noise when results unchanged
* consistently spell derp nodes as "derp-N"
* replace "127.3.3.40:" with "derp-" in CreateEndpoint log output
* stop early DERP setup before SetPrivateKey is called;
it just generates log nosie
* fix stringification of peer ShortStrings (it had an old %x on it,
rendering it garbage)
* describe why derp routes are changing, with one of:

staticcheck defaults to running with no tags set, which only
works if redo hasn't run and generated ver.go. If it has,
we end up with a redeclaration conflict.
