This moves all the terminal writing to a goroutine that updates the
terminal periodically.
In our MITM copier we just use an atomic to add to the total number of
bytes read/written, the goroutine reads the total and updates the
terminal as needed.

Only show progress updates after a time threshold has elapsed in order
to reduce the number of writes to the terminal.
This improves readability of the progress.
Also moves cursor show/hide into the progress printer to reduce chances
if messing up the user's terminal in case of cancellation.

- Instead of rewriting the entire line every time only clear and write
the parts that changed.
- Hide the cursor while writing progress
Both these things make the progress updates significantly easier to

These were deprecated in 6c400a9c2009bba9376ad61ab59c04c1ad675871 (docker 19.03),
but the "Deprecated:" comments were missing a newline before them.
While most IDEs will detect such comments as "deprecated", pkg.go.dev and linters
will ignore them, which may result in users not being aware of them being deprecated.
This patch;
- Fixes the "Deprecated:" comments.
- Changes the var aliases to functions, which is slightly more boilerplating,
but makes sure the functions are documented as "function", instead of shown
in the "variables" section on pkg.go.dev.
- Adds some punctuation and adds "doc links", which allows readers to navigate
to related content on pkg.go.dev.

On Windows, ignore all variables that start with "=" when building an
environment variables map for stack.
For MS-DOS compatibility cmd.exe can set some special environment
variables that start with a "=" characters, which breaks the general
assumption that the first encountered "=" separates a variable name from
variable value and causes trouble when parsing.
These variables don't seem to be documented anywhere, but they are
described by some third-party sources and confirmed empirically on my
Windows installation.
Useful sources:
https://devblogs.microsoft.com/oldnewthing/20100506-00/?p=14133https://ss64.com/nt/syntax-variables.html
Known variables:
- `=ExitCode` stores the exit code returned by external command (in hex
format)
- `=ExitCodeAscii` - same as above, except the value is the ASCII
representation of the code (so exit code 65 (0x41) becomes 'A').
- `=::=::\` and friends - store drive specific working directory.
There is one env variable for each separate drive letter that was
accessed in the shell session and stores the working directory for that
specific drive.
The general format for these is:
`=<DRIVE_LETTER>:=<CWD>` (key=`=<DRIVE_LETTER>:`, value=`<CWD>`)
where <CWD> is a working directory for the drive that is assigned to
the letter <DRIVE_LETTER>
A couple of examples:
`=C:=C:\some\dir` (key: `=C:`, value: `C:\some\dir`)
`=D:=D:\some\other\dir` (key: `=C:`, value: `C:\some\dir`)
`=Z:=Z:\` (key: `=Z:`, value: `Z:\`)
`=::=::\` is the one that seems to be always set and I'm not exactly
sure what this one is for (what's drive `::`?). Others are set as
soon as you CD to a path on some drive. Considering that you start a
cmd.exe also has some working directory, there are 2 of these on start.
All these variables can be safely ignored because they can't be
deliberately set by the user, their meaning is only relevant to the
cmd.exe session and they're all are related to the MS-DOS/Batch feature
that are irrelevant for us.

The error returned from "os/exec".Command when attempting to execute a
directory has been changed from syscall.EACCESS to syscall.EISDIR on
Go 1.20. 2b8f214094
Consequently, any runc runtime built against Go 1.20 will return an
error containing 'is a directory' and not 'permission denied'. Update
the string matching so the CLI exits with status code 126 on 'is a
directory' errors (EISDIR) in addition to 'permission denied' (EACCESS).

This behavior should not break any more use cases than before.
Previously, if the mismatch occured, we would actually push a manifest
that we then never referred to in the manifest list! If this was done in
a new repository, the command would fail with an obscure error from the
registry - the content wouldn't exist with the descriptor we expect it
to.

This comment was added in 7929888214
when this code was still in the Moby repository. That comment doesn't appear
to apply to the CLI's usage of this struct though, as nothing in the CLI
sets this field (or uses it), so this should be safe to remove.
