Revert the (int -> size_t) transition of the "cmdEpoch" field of
the struct Command that was part of [ff3f6a12a8d099ef], and related changes.
This change broke the ability of Itcl 3.4 built against Tcl 8.6 headers
to successfully [load] into and operate in a Tcl 8.7 interp.
"Command" is a private struct, and Itcl 3 should have respected that, but
it has not, and changing the size of the cmdEpoch field broke the ability
of Itcl 3 to operate on later fields of the struct, notably the deleteProc,
which it makes extensive use of.
I believe we should keep the change in the Tcl 9 sources.
