In the contents of COPY/ADD, we perform expansion on variables using a
lexer. However, this lexer, by default, removes quotes as well as
expanding variables - this isn't really the kind of behavior we're
after, as it feels quite unintuitive.
To fix this, we introduce a new ExpandRaw function, which commands can
implement that implement an alternative expansion that preserves quotes
(and possibly other characters/features in the future).
Additionally, we introduce new tests to more clearly define the desired
behavior. One major note is that backslashes are not passed directly,
and are processed, following normal escape rules (so that we can use `$`
symbols directly).

Previously, heredoc names were restricted to simple alphanumeric
strings. However, heredocs should support much more complex use-cases,
including quoting anywhere, as well as allowing special symbols like `.`
for easily expressing file extensions.
This patch adds support for these more complex cases, by using the shell
lexer to parse each heredoc name. Additionally, we include improvements
to the lexer to optionally preserve escape tokens to avoid problems when
lexing words that have already been lexed before.

This provides the basic functionality for the parser to recognize and
parse provided heredocs in supported commands.

If the line-continuation marker (`\`) is escaped, it should not be
treated as such, but as a literal backslash.

By default, Ubuntu or Debian based "apt" or "apt-get" system installs recommended but not suggested packages .
By passing "--no-install-recommends" option, the user lets apt-get know not to consider recommended packages as a dependency to install.
This results in smaller downloads and installation of packages .

Since we use `NewLabelCommand()` instead of `addNodesForLabelOption()`
to create the 'LABEL' commands from '--label' options, so all the related
functions should be removed.

This PR has the API changes described in https://github.com/moby/moby/issues/34617.
Specifically, it adds an HTTP header "X-Requested-Platform" which is a JSON-encoded
OCI Image-spec `Platform` structure.
In addition, it renames (almost all) uses of a string variable platform (and associated)
methods/functions to os. This makes it much clearer to disambiguate with the swarm
"platform" which is really os/arch. This is a stepping stone to getting the daemon towards
fully multi-platform/arch-aware, and makes it clear when "operating system" is being
referred to rather than "platform" which is misleadingly used - sometimes in the swarm
meaning, but more often as just the operating system.

Commit 8d1ae76dcbbb73d8e20c6a14a7d3fe2410b95f55 added
deprecation warnings for empty continuation lines,
but also treated comment-only lines as empty.
This patch distinguishes empty continuation lines
from comment-only lines, and only outputs warnings
for the former.

This fix is related to 29005 and 24693. Currently in `Dockerfile`
empty lines will continue as long as there is line escape before.
This may cause some issues. The issue in 24693 is an example.
A non-empty line after an empty line might be considered to be a
separate instruction by many users. However, it is actually part
of the last instruction under the current `Dockerfile` parsing
rule.
This fix is an effort to reduce the confusion around the parsing
of `Dockerfile`. Even though this fix does not change the behavior
of the `Dockerfile` parsing, it tries to deprecate the empty line
continuation and present a warning for the user. In this case,
at least it prompt users to check for the Dockerfile and avoid
the confusion if possible.
