Log Message:
* generic/tclMain.c (Tcl_Main): [Bug 801429]: Factor out the holding of the
client-installed main loop function into thread-specific data.

***POTENTIAL INCOMPATIBILITY***
Code that previously tried to set the main loop from another thread will now
fail. On the other hand, there is a fairly high probability that such programs
would have been failing before due to the lack of any kind of inter-thread
memory barriers guarding accesses to this part of Tcl's state.
