logtail: require Buffer.Write to not retain the provided slice (#11617)
Buffer.Write has the exact same signature of io.Writer.Write.
The latter requires that implementations to never retain
the provided input buffer, which is an expectation that most
users will have when they see a Write signature.

The current behavior of Buffer.Write where it does retain
the input buffer is a risky precedent to set.
Switch the behavior to match io.Writer.Write.

There are only two implementations of Buffer in existence:
* logtail.memBuffer
* filch.Filch

The former can be fixed by cloning the input to Write.
This will cause an extra allocation in every Write,
but we can fix that will pooling on the caller side
in a follow-up PR.

The latter only passes the input to os.File.Write,
which does respect the io.Writer.Write requirements.

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.

David Crawshaw 6ddbcab71e logtail: rename the unused CheckLogs to DrainLogs
Its semantics has changed slightly, this will let us use it to
drive batched logging in special circumstances.
