revlog: move the splitting-inline-revlog logic inside the inner object
This is another large IO block that we need to move within the inner object if
we want's it to be self sufficient.
Define helpers.
$ hg_log () { hg log -G -T "{rev}:{node|short}"; }
$ commit () { echo "foo - ${2:-$1}" > $1; hg commit -Aqm "Edited $1"; }
$ strip() { hg --config extensions.strip= strip -q -r "$1" ; }
Setup hg repo.
$ hg init repo
$ cd repo
$ touch x; hg add x; hg commit -m "initial"
$ hg clone -q . ../clone
$ commit a
$ cd ../clone
$ commit b
$ hg pull -q ../repo
$ cat .hg/cache/branch2-visible

$ strip '1:'
The branchmap cache is not adjusted on strip.
Now mentions a changelog entry that has been stripped.

Not adjusted on commit, either.

On pull we end up with the same tip, and so wrongly reuse the invalid cache and crash.
$ hg pull ../repo 2>&1 | grep 'ValueError:'
ValueError: node a3498d6e39376d2456425dd8c692367bdbf00fa2 does not exist (known-bad-output !)
