Differences From Artifact [f7e5cbc1fd]:

• File generic/tclBinary.c — part of check-in [3ef69dfebe] at 2016-12-01 13:20:47 on branch trunk — Created a new "proper bytearray" Tcl_ObjType so we can use bytearrays as bytearrays without all this fussing about over purity. (user: dgp size: 76397)

To Artifact [1aecd08f7f]:

• File generic/tclBinary.c — part of check-in [088e1f413e] at 2016-12-01 17:25:40 on branch trunk — So long as we register only one, we can have multiple Tcl_ObjTypes with the same name. This smooths migration. See obj-2.2 and tclsqlite usage. (user: dgp size: 76390)
