  1. Add --force flag to cargo install 

    Close #2082

Adding `--force` (`-f`) instructs cargo to overwrite existing binaries
(updating the metadata accordingly).
This allows updating crates via `cargo install -f <crate>`.

Installation happens in two stages now: binaries are copied into a
temporary subdirectory of the destination first, then moved into
destination. This should catch some errors earlier.

In case of installation error cargo will remove new binaries but won't
attempt to undo successful overwrites.

  2. cargo-install: move binaries from the build dir if possible 

    Try moving the binaries (and fall back to copying) if the build
directory is a temporary one (source isn't a local path).
