fsx: add support for recording operations to a file

Browse Source 
Usually, fsx dumps an .fsxops file on failure with same basename
as work file and possibly under dirctory specified by -P dirpath.

The --record-ops[=opsfile] flag can be use to dump ops file also
on success and to optionally specify the ops file name.
