abort: added support for histedit

This patch adds the support for `histedit` in `hg abort` plan.

As seperate `hgaborthistedit()` function is created to handle
independent calls for abortion of `histedit`. This function is
then registered as `abortfunc` for state detection API.

hg abort in case of `histedit` also supports ` history-editing-backup`
config option.

Results are shown as tests.
