[IMP] core: better API for flush() and invalidate()

This provides a new API for those operations, in order to make the
distinction between the use cases more explicit.  The former API was
using obscure parameter combinations to correspond to various cases.

In the summary below, `fnames` is an iterable of field names.  If the
parameter is not given, it means "all fields" in the given context.
Note that method recompute() is now mostly private, as it should not be
used in business code.

    # process pending computations and updates
    records.env.flush_all()                # all fields of all models
    records.flush_model(fnames)            # the fields of all records of the model
    records.flush_recordset(fnames)        # the fields of the given records

    # process pending computations, became non-public methods
    records.env._recompute_all()           # all fields of all models
    records._recompute_model(fnames)       # the fields of all records of the model
    records._recompute_recordset(fnames)   # the fields of the given records

    # invalidate the cache of fields
    records.env.invalidate_all()           # all fields of all models
    records.invalidate_model(fnames)       # the fields of all records of the model
    records.invalidate_recordset(fnames)   # the fields of the given records
