clonebundles: adds a auto-generate.serve-inline option

This new option disable the "external" serving of auto generated bundle in favor
of using the new "inline bundle" feature that allow serving such bundle through
the mercurial protocol.

This is a less efficient, but very easy to setup way to start using clone bundle.

create source repository

  $ hg init repo
  $ cd repo
  $ echo a > a
  $ echo b > b
  $ hg ci -Am addfile
  adding a
  adding b
  $ cat "$TESTDIR/binfile.bin" >> a
  $ cat "$TESTDIR/binfile.bin" >> b
  $ hg ci -Am changefiles

make another commit to create files larger than 1 KB to test
formatting of final byte count

  $ cat "$TESTDIR/binfile.bin" >> a
  $ cat "$TESTDIR/binfile.bin" >> b
  $ hg ci -m anotherchange

don't sit forever trying to double-lock the source repo

  $ hg relink .
  relinking $TESTTMP/repo/.hg/store to $TESTTMP/repo/.hg/store
  there is nothing to relink

  $ cd ..


clone and pull to break links

  $ hg clone --pull -r0 repo clone
