port: new action_environment and/or environment mode

[pixilla (Bradley Giesbrecht)]

I've wanted something like this for some time. This may not be worth the action/mode bloat so I present it here to gauge popularity.

port -e version
port env
port -q env

Interesting, but is "env" (environment) the best choice of terms here? I would expect port env to print out the environment variables as they are set for and seen by commands launched through the port command, optionally for the given port(s). One could add something like the following to macports::environment:

    set shenv {}
    foreach keyval [exec /usr/bin/printenv] {
        lappend shenv $keyval
    }
    if {![macports::ui_isset ports_quiet]} {
        lappend mpenv "$macports::ui_prefix shell environment: [join $shenv { }]"
    } else {
        lappend mpenv "shell environment [join $shenv { }]"
    }

(and of course let the command accept port names so that variables set by the Portfile(s) show up in printenv).

Dupe of #33629?

Replying to jmroot:

Dupe of #33629?

In spirit; judging from the patchfiles Bradley's proposal is a less elaborate implementation. It's not impossible though that he provided me with the patch attached here.
