Allows calling exeve() in processes where the event loop has not yet been run (Darwin's execve() fails in processes with more than one thread), in particular allows embedders to call fork() followed by execve(), previously the pthread_atfork() child handler's call to Tcl_InitNotifier() would immediately recreate the notifier thread in the child after a fork. * macosx/tclMacOSXNotify.c (Tcl_InitNotifier): add support for * unix/tclUnixFCmd.c (DoRenameFile, CopyFileAtts): weakly importing * unix/tclUnixInit.c (TclpSetInitialEncodings): symbols not available on OSX 10.2 or 10.3, enables binaires built on later OSX versions to run on earlier ones. * macosx/README: document how to enable weak-linking; cleanup. * unix/tclUnixPort.h: add support for weak-linking; conditionalize AvailabilityMacros.h inclusion; only disable realpath on 10.2 or earlier when threads are enabled. * unix/tclLoadDyld.c (TclpLoadMemoryGetBuffer): change runtime Darwin * unix/tclUnixInit.c (TclpInitPlatform): release check to use global initialized once. * unix/tclUnixFCmd.c (DoRenameFile, TclpObjNormalizePath): add runtime Darwin release check to determine if realpath is threadsafe. * unix/configure.in: add check on Darwin for compiler support of weak * unix/tcl.m4: import and for AvailabilityMacros.h header; move Darwin specific checks & defines that are only relevant to the tcl build out of tcl.m4; restrict framework option to Darwin; cleanup quoting. * unix/configure: autoconf-2.13 * unix/tclLoadDyld.c (TclpLoadMemory): * unix/tclUnixPipe.c (TclpCreateProcess): fix signed-with-unsigned comparison and other warnings from gcc4 -Wextra.

Together, these take care of the housekeeping for "values" (things that can be held in a Tcl_Obj) that are global across a whole process. That is, they are shared among multiple threads, and epoch and mutex protection must govern the validity of cached copies maintained in each thread. * generic/tclNotify.c: Modified TclInitNotifier() to tolerate being called multiple times in the same thread. * generic/tclEvent.c: Dropped the unused argv0 argument to TclInitSubsystems(). Removed machinery to unsure only one TclInitNotifier() call per thread, now that that is safe. Converted Tcl(Get|Set)LibraryPath to use a ProcessGlobalValue, and moved them to tclEncoding.c. * generic/tclBasic.c: Updated caller. * generic/tclInt.h: TclpFindExecutable now returns void. * unix/tclUnixFile.c: * win/tclWinFile.c: * win/tclWinPipe.c: * generic/tclEncoding.c: Built new encoding search initialization on a foundation of ProcessGlobalValues, exposing new routines Tcl(Get|Set)EncodingSearchPath. A cache of a map from encoding name to directory pathname keeps track of where encodings are available for loading. Tcl_FindExecutable greatly simplified into just three function calls. The "library path" is now misnamed, as its only remaining purpose is as a foundation for the default encoding search path. * generic/tclInterp.c: Inlined the initScript that is evaluated by Tcl_Init(). Added verification after initScript evaluation that Tcl can find its installed *.enc files, and that it has initialized [encoding system] in agreement with what the environment expects. [tclInit] no longer driven by the value of $::tcl_libPath; it largely constructs its own search path now, rather than attempt to share one with the encoding system. * unix/tclUnixInit.c: TclpSetInitialEncodings factored so that a new * win/tclWinInit.c: routine TclpGetEncodingNameFromEnvironment can reveal that Tcl thinks the [encoding system] should be, even when an incomplete encoding search path, or a missing *.enc file won't allow that initialization to succeed. TclpInitLibraryPath reworked as an initializer of a ProcessGlobalValue. * unix/tclUnixTest.c: Update implementations of [testfindexecutable], [testgetdefenc], and [testsetdefenc]. * tests/unixInit.test: Corrected tests to operate properly even when a value of TCL_LIBRARY is required to find encodings. * generic/tclInt.decls: New internal stubs: TclGetEncodingSearchPath, TclSetEncodingSearchPath, TclpGetEncodingNameFromEnvironment. These are candidates for public exposure by future TIPs. * generic/tclIntDecls.h: make genstubs * generic/tclStubInit.c: * generic/tclTest.c: Updated [testencoding] to use * tests/encoding.test: Tcl(Get|Set)EncodingSearchPath. Updated tests.
