rebase: initial support for multiple destinations

This patch defines `SRC` (a single source revision) and `ALLSRC` (all source
revisions) to be valid names in  `--dest` revset if `--src` or `--rev` is
used. So destination could be defined differently according to source
revisions. The names are capitalized to make it clear they are "dynamically
defined", distinguishable from normal revsets (Thanks Augie for the
suggestion).

This is useful, for example, `-r 'orphan()' -d 'calc-dest(SRC)'` to solve
instability, which seems to be a highly wanted feature.

The feature is not completed, namely if `-d` overlaps with `-r`, things
could go wrong. A later patch will handle that case.

The feature is also gated by `experimental.rebase.multidest` config option
which is default off.
