manifest: remove dependency on manifestrevlog being able to create trees
A future patch will be removing the read() function from the manifest class.
Since manifestrevlog currently depends on the read function that manifest
implements (as a derived class), we need to break the dependency from
manifestrevlog to read(). We do this by adding an argument to
manifestrevlog.write() which provides it with the ability to read a manifest.
This is good in general because it further separates revlog as the storage
format from the actual inmemory data structure implementation.

When Mercurial accepts more than one revision, they may be specified individually, or provided as a topologically continuous range, separated by the ":" character. The syntax of range notation is [BEGIN]:[END], where BEGIN and END are revision identifiers. Both BEGIN and END are optional. If BEGIN is not specified, it defaults to revision number 0. If END is not specified, it defaults to the tip. The range ":" thus means "all revisions". If BEGIN is greater than END, revisions are treated in reverse order. A range acts as a closed interval. This means that a range of 3:5 gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
