revlog: add a magic null revision to our index

We expand our index by one entry so that index[nullrev] points to a
unique entry, the null revision. This naturally eliminates numerous
extra tests in the performance-sensitive index access functions, most
of which are now trivial again.

Adding new entries is now done with insert(-1, e) rather than
append(e).

#!/bin/sh

"$TESTDIR/hghave" symlink || exit 80

hg init a
ln -s a link
cd a
echo foo > foo
hg status
hg status ../link
