Upgrade from Winsock 1.1 to Winsock 2.2, which is always available on Win2000+. See: [http://msdn.microsoft.com/en-us/library/windows/desktop/ms742213%28v=vs.85%29.aspx] for details. 
Move winsock initialization to TclpInitPlatform(void), so we can be sure everywhere that we have an initialized winsock2. 
Stub entries for TclWinGetServByName/TclWinGetSockOpt/TclWinSetSockOpt are no longer necessary (will be removed in 9.0, but are kept in 8.x)

Remove unused variable, don't use deprecated function, some formatting.

Test for [d19a30db57].
[d19a30db57] Fixed segfault in [clock] internals.  Includes test.
Test for [d19a30db57] extended
Repair new test so all parts will be effective.
[d19a30db57] More testing.
Remove all win95-specific test-cases, since Windows 95 is not supported any more.
Simplify reflected channels.
Instead of having two modes of Close operations and the need to choose
between them with a special value of the methods field, when the initialize
pass fails for some reason, simply do not create the channel so there's
nothing that needs closing.  Then the methods field no longer holds anything
used, so eliminate it.  All the methods checking is done by [chan create].
Reflected channels.  Keep a set of method names cached so we don't create
new each operation, and we can benefit from any lookup info cached in intreps.
Merge reflected channel improvements.
Another test exposing another segfault.
Added a refcounting mechanism to ChannelBuffers.  Other edits to
stop segfaults in tests iocmd-21.2[12].
Merge refcounting machinery for ChannelBuffer.
Memory leak after thread exit, fixed (alloc cache released by exit), belong to ticket [3493120]
