Rework internal errors. This changes the behavior of "internal" errors, which were previously hidden and only displayed with `--verbose`. The changes here: - `internal` now means "a cargo bug", and is always displayed and requests that the user file a bug report. - Added `VerboseError` to signify an error that should only be displayed with `--verbose`. This is only used in one place, to display the `rustc` compiler command if the compiler exited with a normal error code (i.e. not a crash). - Audited the uses of internal errors, and promoted some to normal errors, as they seemed to contain useful information, but weren't necessarily bugs in cargo. - Added some details to some errors. - Sometimes the "run with --verbose" message wasn't being printed when I think it should. This happened when rustc failed while other rustc processes were running. Another case was with `cargo install` installing multiple packages, and one of them fails.
