This removes the ***POTENTIAL INCOMPATIBILITY*** for channel drivers it introduced. This has become possible due to Expect gaining a BlockModeProc and now handling blockingg and non-blocking modes correctly. Thus [SF Tcl Bug 943274] is still fixed if a recent enough version of Expect is used. * doc/CrtChannel.3: Added warning about usage of a channel without a BlockModeProc.

It is possible to get around it if the actual read operation is defered and not executed in the event handler itself. Instead of tracking if we are in an read caused by a synthesized fileevent we now track if the OS has delivered a true event = actual data and bypass the driver if a read finds that there is no actual data waiting. The flag is cleared by a short or full read.

New functions CloseWrite, CloseChannelPart, new flag CHANNEL_CLOSEDWRITE. * tests/chanio.test (chanio-28.[67]): Reactivated these tests. Replaced tclsh -> [interpreter] to get correct executable for the pipe process, and added after cancel to kill the fail timers when we are done. Removed the explicits calls to [flush], now that [close] handles this correctly.

Because of this the general I/O core has to take more care than usual to preserve the semantics of non-blocking channels. * generic/tclIO.c (Tcl_ReadRaw): Do not read from the driver if the channel is non-blocking and the fileevent causing the read was generated by a timer. We do not know if there is data available from the OS. Instead of going to the OS for more and potentially blocking we simply signal EWOULDBLOCK to the higher levels to cause the system to wait for true fileevents. (GetInput): Same as before. (ChannelTimerProc): Added set and clear of CHANNEL_TIMER_FEV. * generic/tclIO.h (CHANNEL_TIMER_FEV): New flag for channels. Is set if a fileevent was generated by a timer, the channel is not blocking and the driver did not provide a blockmodeproc. In that case the I/O core has to be especially careful about going to the driver for more data.

Note: This structure is shared by all channels in a stack of transformations. * generic/tclIO.c (Tcl_CreateChannel, lines 1058-1065): Modified to store the Id of the current thread in the 'ChannelState' of the new channel. * generic/tclIO.c (Tcl_SpliceChannel, lines 2265-2270): Modified in the same manner as 'Tcl_CreateChannel' as the channel will be managed by the current thread afterward. * generic/tclIO.c (Tcl_GetChannelThread, lines 1478-1503): * generic/tcl.decls (Tcl_GetChannelThread, lines 1504-1506): New API function to retrieve the Id of the managing thread from a channel. Implementation and declaration. * generic/tclTest.c (TestChannelCmd, lines 4520-4532): Added subcommand 'mthread' to query a channel about its managing thread.
