[Omake] SVN Commit: OMake Build System [0.9.8.x] (Rev. 12122)

[Jason J. Hickey]

Represent ValChannel as an int ref; the environment has the table
int ref -> Lm_channel.t.  This adds a level of indirection, but
it means that values will never, ever include functions.  This
resolves a problem David was seeing 'Invalid_argument "functional value"'.

The reason for the int ref is to get unique identifiers, so that
marshaled channels will unmarshal to new handles.  This means
we no longer have a need for venv_marshal, which pretended to
close all the channels before marshaling.

The table is Omake_handle_table.IntHandleTable.
