* bugfix: take into account the fact that "coroutine" is no longer part of base library in Lua 5.2
* bugfix: if "bit32" was listed in the libraries, it wouldn't open (library list parsing failing on digits)
* bugfix: Use luaL_requiref() to open standard libraries in Lua 5.2 as we should
* bugfix: any Lua state created by Lanes reuses the allocator function of the originating state
* bugfix: don't call on_state_create() while GC is suspended during lua state initialization

* raise an error if lane generator libs specification contains a lib more than once
* bit32 is a valid lib name in the libs specification (silently ignored by the Lua 5.1 build)
* improved lanes.nameof to search inside table- and userdata- metatables for an object's name
* fixed an unwarranted error when trying to discover a function name upon a failed transfer
* contents of package.[path,cpath,preload,loaders|searchers] are pulled *only once* inside keeper states at initialisation
* Lua function upvalues equal to the global environment aren't copied by value, but bound to the destination's global environment
especially useful for Lua 5.2 _ENV
* fixed loading of base libraries that didn't create the global tables when built for Lua 5.2

* new method linda:dump() that outputs the full contents of a linda as a table, also linked to __towatch for Decoda support
* linda:receive() API change!
* instead of [val, key], linda:receive( timeout, key) returns [key, val]
* instead of [val, [...]], linda:receive( timeout, linda.batched key) returns [key, val[, ...]]
this is to unify the return values of regular and batched mode, and to be able to tell when batched mode is interrupted by a lane cancellation
* fixed Lua 5.2 build to take into account the "loaders"->"searchers" name change in 'package' module.
* a bit of html cleanup and added some infos in the documentation regarding the Lanes internals

* lane.status can return "killed" if lane was forcefully killed with lanes:cancel()
* lane:join(): return nil, "killed" if called on a killed lane.
* lane[<n>]: produces [1] = nil, [2] = "killed" if the lane was killed
* lane:join(): fixed an assertion in debug builds when joining a lane forcefully cancelled with lane:cancel( <x>, true).
* indexing a lane with a string other than "join", "cancel" or "status" raises an error.
* fixed configure() to correctly apply defaults when they are missing from the provided settings
* added a shutdown_timeout to control the duration Lanes will wait for graceful termination of running lanes at application shutdown. Default is 0.25.
Among other things, fixes issue #31.

when atexit() handlers are processed
* Lua 5.2-style module:
* module() is no longer used to implement lanes.lua
* a global "lanes" variable is no longer created when the module is required
* the Lanes module table is returned instead
* Lanes must be initialized before used:
* the first occurence of 'require "lanes"' produces a minimal interface that only contains a configure() function
* the remainder of the interface is made available once this function is called
* subsequent calls to configure() do nothing
* configure() controls the number of keeper states and the startup of timers
* LuaJIT 2 compatibility
* non-Lua functions are no longer copied by creating a C closure from a C pointer, but through 2-way lookup tables
* this means that if a lane function body pulls non-Lua functions, the lane generator description must contain the list of libraries and modules that exports them
* introduces a change in configuration .globals management: contents are copied *after* std libs are loaded
* new .required configuration entry to list modules that must be require()'ed before lane body is transferred
* lane:cancel() wakes up waiting lindas like what is done at lane shutdown

a killed thread's VM.
* exposed cancel_test() in the lanes to enable manual testing for cancellation requests.
* removed kludgy {globals={threadName}} support, replaced with a new function set_debug_threadname().

- Refactor lane proxy implementation: it is now a full userdata instead
of a table, and its methods are implemented in C instead of Lua.
* its metatable is no longer accessible.
* writing to the proxy raises an error.
* it is no longer possible to overwrite its join() and cancel() methods
- when a deep userdata idfunc requests a module to be required, manually
check that it is not loaded before requiring it instead of relying on
the require function's loop detection feature.
- when a module must be required, raise an error if the 'require' function
is not found in the target state.
- we know Lanes is loaded in the master state, so we don't force it
to be required in every lane too when a linda deep userdata is copied.

github repository becomes the official Lanes source codebase.
Note that Asko's SVN server holds version 2.0.9, whereas this is version 2.0.10, but I don't see any real need to update SVN if it is to become deprecated.
Next steps:
- upgrade the rockspec to the latest version
- make the html help available online somewhere
