* tests/thread.test: ::errorInfo and ::errorCode so that string
* tests/trace.test: reported to variable traces are fully
qualified in agreement with Tcl 8.4 operations.

global variables ::errorInfo, ::errorCode, ::env and
::tcl_platform: many were relying on the alternative lookup in the
global namespace, that feature is tested specifically in namespace
and variable tests.
The modified testfiles are: apply.test, basic.test, case.test,
cmdIL.test, cmdMZ.test, compExpr-old.test, error.test, eval.test,
event.test, expr.test, fileSystem.test, for.test, http.test,
if.test, incr-old.test, incr.test, interp.test, io.test,
ioCmd.test, load.test, misc.test, namespace.test, parse.test,
parseOld.test, pkg.test, proc-old.test, set.test, switch.test,
tcltest.test, thread.test, var.test, while-old.test, while.test.

Removed several DECACHE_INFO/CACHE_INFO pairs that are no longer
needed for protection because routines like Tcl_SetErrorCode() and
Tcl_AddErrorInfo() can no longer re-enter bytecode execution.
* generic/tclResult.c (TclProcessReturn): Bug fix. Be sure that
a missing -errorinfo option when code == TCL_ERROR causes the
errorInfo field to get reset.
* tests/thread.test (thread-4.4): Test depended on a ::errorInfo
value initialized to "". Added code to test to setup that requirement.

* Overall changes:
(1) Implementation of joinable threads for all platforms.
(2) Additional API's for channels. Required to allow the
thread extension to move channels between threads.
* generic/tcl.decls (lines 1360f): Added Tcl_JoinThread,
Tcl_IsChannelShared, Tcl_IsChannelRegistered, Tcl_CutChannel,
Tcl_SpliceChannel, Tcl_IsChannelExisting and
Tcl_ClearChannelHandlers (slots 394 to 400).
* generic/tclIO.c: Implemented Tcl_IsChannelRegistered,
Tcl_IsChannelShared, Tcl_CutChannel, Tcl_SpliceChannel,
Tcl_IsChannelExisting and Tcl_ClearChannelHandlers.
Tcl_CutChannel uses code from CloseChannel. Replaced this code
by a call to Tcl_CutChannel. Replaced several code fragments
adding channels to the channel list with calls to
Tcl_SpliceChannel. Removed now unused variables from
CloseChannel and Tcl_UnstackChannel. Tcl_ClearChannelHandlers
uses code from Tcl_Close. Replaced this code by a call to
Tcl_ClearChannelHandlers. Removed now unused variables from
Tcl_Close. Added the subcommands 'cut', 'forgetch', 'splice' and
'isshared' to the test code
(TclTestChannelCmd).
* unix/tclUnixThread.c: Implemented Tcl_JoinThread using the
pthread-functionality.
* win/tclWinThrd.c: Fixed several small typos in comments.
Implemented Tcl_JoinThread using a platform independent
emulation layer (see generic/tclThreadJoin.c below). Added
'joinLock' to serialize Tcl_CreateThread and TclpExitThread to
prevent a race for joinable threads.
* mac/tclMacThrd.c: Implemented Tcl_JoinThread using a platform
independent emulation layer (see generic/tclThreadJoin.c
below). Due to the cooperative nature of threading on this
platform the race mentioned above is not present.
* generic/tclThreadJoin.c: New file. Contains a platform
independent emulation layer helping in the implementation of
joinable threads for the win and mac platforms.
* generic/tclInt.h: Added declarations for TclJoinThread,
TclRememberJoinableThread and TclSignalExitThread. These
procedures define the API of the emulation layer for joinable
threads (see generic/tclThreadJoin.c above).
* win/Makefile.in:
* win/makefile.vc: Added generic/tclTheadJoin.o to the rules.
* mac/: I don't know to which file generic/tclTheadJoin.o has to
be added to so that it compiles. Sorry.
* unix/tclUnixChan.c: #ifdef'd the thread-local list of file
channels as it prevents us from transfering channels. To restore
this we may need an extended interface to drivers in the
future. Target: 9.0. Found while testing the new transfer of
channels. The information in this list for a channel was left
behind and then crashed the system during finalization.
* generic/tclThreadTest.c: Added -joinable flag to 'testthread
create'. Added subcommand 'testthread join'.
* doc/CrtChannel.3: Added documentation for Tcl_IsChannelRegistered,
Tcl_IsChannelShared, Tcl_CutChannel, Tcl_SpliceChannel,
Tcl_IsChannelExisting and Tcl_ClearChannelHandlers.
* doc/Thread.3: Added documentation for Tcl_JoinThread.
* tests/thread.test: Added tests for joining of threads.

calls
threadReap at the beginning and end of the test, inside the test body. This fixes
the problem where the test suite was exiting on a call to threadReap (reap was
killing the main thread by accident because other tests were leaving threads
running and setting mainthread to be the list of running threads).
