* All of the changes below belong to TIP #10 [Tcl I/O Enhancement:
Thread-Aware Channels]. See also [Patch #403358] at SF.
* generic/tclIO.h (struct ChannelState, line 236f): Extended the
structure with a new field of type 'Tcl_ThreadId' to hold the id
of the thread currently managing all channels with this state.
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.
