pull: introduce a pull.rebase option to enable --rebase

Currently we either need to set branch.<name>.rebase for existing
branches if we'd like "git pull" to mean "git pull --rebase", or have
the forethought of setting "branch.autosetuprebase" before we create
the branch.

Introduce a "pull.rebase" option to globally configure "git pull" to
mean "git pull --rebase" for any branch.

This option will be considered at a lower priority than
branch.<name>.rebase, i.e. we could set pull.rebase=true and
branch.<name>.rebase=false and the latter configuration option would
win.
