revlog: calculate base revisions iteratively

This is in preparation for generaldelta, where the revlog entry base field is
reinterpreted as the deltaparent. For that reason we also rename the base
function to chainbase.

Without generaldelta, performance is unaffected, but generaldelta will suffer
from this in _addrevision, since delta chains will be walked repeatedly.
A cache has been added to eliminate this problem completely.

try converting darcs1 repository

  $ hg clone -q "$TESTDIR/bundles/darcs1.hg" darcs
  $ hg convert -s darcs darcs/darcs1 2>&1 | grep darcs-1.0
  darcs-1.0 repository format is unsupported, please upgrade

initialize darcs repo

  $ mkdir darcs-repo
  $ cd darcs-repo
  $ darcs init
  $ echo a > a
  $ darcs record -a -l -m p0
  Finished recording patch 'p0'
  $ cd ..

branch and update

  $ darcs get darcs-repo darcs-clone >/dev/null
  $ cd darcs-clone
  $ echo c >> a
  $ echo c > c
  $ darcs record -a -l -m p1.1
  Finished recording patch 'p1.1'
  $ cd ..

update source

  $ cd darcs-repo
  $ echo b >> a
  $ echo b > b
  $ darcs record -a -l -m p1.2
  Finished recording patch 'p1.2'

  $ darcs pull -a ../darcs-clone
  Backing up ./a(-darcs-backup0)
  We have conflicts in the following files:
  ./a
  Finished pulling and applying.

  $ echo f > f
  $ mkdir dir
  $ echo d > dir/d
  $ echo d > dir/d2
  $ darcs record -a -l -m p2

test file and directory move

  $ darcs mv f ff

Test remove + move

  $ darcs remove dir/d2
  $ rm dir/d2
  $ darcs mv dir dir2
  $ darcs record -a -l -m p3
  Finished recording patch 'p3'

test utf-8 commit message and author

  $ echo g > g

darcs is encoding agnostic, so it takes whatever bytes it's given

  $ darcs record -a -l -m 'p4: desc ñ' -A 'author ñ'
  Finished recording patch 'p4: desc \xc3\xb1' (esc)

Test latin-1 commit message

  $ echo h > h
  $ printf "p5: desc " > ../p5
  $ python -c 'print "".join([chr(i) for i in range(128, 256)])' >> ../p5
  $ darcs record -a -l --logfile ../p5

The converter does not currently handle patch conflicts very well.
When they occur, it reverts *all* changes and moves forward,
letting the conflict resolving patch fix collisions.
Unfortunately, non-conflicting changes, like the addition of the
"c" file in p1.1 patch are reverted too.
Just to say that manifest not listing "c" here is a bug.
