import: use "getcommiteditor()" instead of explicit editor choice

This patch also enhances "test-import-bypass.t" and "test-import.t",
because "hg import" hasn't been explicitly tested around editor
invocation and "--edit" option.

This patch explicitly tests below:

    - with "--bypass" (regardless of "--edit"):
        - not invoked, if the patch contains the commit message
        - not invoked, if the commit message is explicitly specified
        - invoked, otherwise (just adding comment)

    - without "--bypass":
        - with "--edit":
            - not invoked, if "--no-commit" is not specified
            - invoked, otherwise
        - without "--edit":
            - not invoked, if the patch contains the commit message
            - not invoked, if "--message" or "--logfile" is specified
              (just adding comment)
            - invoked, otherwise

'''helper extension to measure memory usage

Reads current and peak memory usage from ``/proc/self/status`` and
prints it to ``stderr`` on exit.
