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

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')

io and os packages.

49a3fcae78 log/filelogger: make filelogger remove redundant date before adding a date
At some point since filelogger was added on Windows, the log hierarchy
above it changed such that a log.Printf writes to filelogger and includes
the log package's own date. But then filelogger adds another.

Rather than debug everything above and risk removing the prefix when
run by tailscaled, instead just remove the log package's prefix
very late right before we go to add the filelogger's own.

280c84e46a ipn/ipnserver, paths, logpolicy: move Window config files out of %LocalAppData%
C:\WINDOWS\system32\config\systemprofile\AppData\Local\
is frequently cleared for almost any reason: Windows updates,
System Restore, even various System Cleaner utilities.

The server-state.conf file in AppData\Local could be deleted
at any time, which would break login until the node is removed
from the Admin Panel allowing it to create a new key.

Carefully copy any AppData state to ProgramData at startup.
If copying the state fails, continue to use AppData so at
least there will be connectivity. If there is no state,
use ProgramData.

We also migrate the log.conf file. Very old versions of
Tailscale named the EXE tailscale-ipn, so the log conf was
tailscale-ipn.log.conf and more recent versions preserved
this filename and cmdName in logs. In this migration we
always update the filename to
c:\ProgramData\Tailscale\tailscaled.log.conf

420838f90e log/filelogger: move our Windows disk file writing+rotation package here
It's still Windows-only for now but it's easy to de-Windows-ify when needed.

Moving it out of corp repo and into tailscale/tailscale so we can use
it in ipnserver.BabysitProc.

log/logheap: properly document LogHeap as performing HTTP upload (#741)
LogHeap no longer logs to os.Stderr and instead uploads
the heap profile by means of an HTTP POST request to the
target URL endpoint.

While here, also ensured that an error from pprof.WriteHeapProfile
isn't ignored and will prevent the HTTP request from being made
if non-nil.
