revlog: group delta computation methods under _deltacomputer object

Extracting these methods from revlog will allow changing the implementation of
the deltacomputer, by providing this interface:
  __init__(self, revlog) - constructor that initialize the object from a given
                           revlog
  buildtext(self, revinfo, fh) - builds the fulltext version of a revision from
                                 a _revisioninfo object and the file handle to
                                 the .d (or .i for inline mode) file.
  finddeltainfo(self, revinfo, fh) - find a revision in the revlog against
                                     which it is acceptable to build a delta,
                                     and build the corresponding _deltainfo.

It should now be easier to write an experimental feature that would replace
_deltacomputer by another object, for example one that would know how to
parallelize the delta computation in order to quicken the storage of multiple
revisions.
