* fix lanes.threads() not being available in a lane where
lanes.configure() settings didn't contain track_lanes although the
initial configure() call did.
* require "lanes".configure() sequence is only necessary at the first
require "lanes".
* fix a crash at application shutdown where in some situations we could
deinitialize the protected allocator mutex while a lane was still using
it.
* fix timers broken by change 69

no longer call core.configure with dummy params when requiring lanes
more than once (fixes potential multithreading issues with LuaJIT
allocator)
activated EnableCrashingOnCrashes() Win32 debug builds
fixed some comments in code

* lane:cancel(<negative-timeout>) only causes cancel_test() to return
true but won't interrupt execution of the lane during linda operations
* more explicit errors when trying to transfer unknown source functions
(with new configure option verbose_errors)
* default options wrap allocator around a mutex when run by LuaJIT

* stricter validation of with_timers config option: validator was accepting any non-boolean value
* new configuration option protect_allocator for VMs with thread unsafe allocators (such as LuaJIT)
* removed some obsolete bits of dead code

* new lanes.h header and API call luaopen_lanes_embedded() for embedders
* "lanes.core" is an acceptable library in the generator libs argument
* library "*" wildcard also opens lanes.core
* tweaked code for Xbox 360 build

* new: API lanes.require(), use it instead of regular require() for modules that export C functions you need to send over.
* new: lanes no longer require 'lanes.core' by default in every created state. Use {required={"lanes.core"}} if you need to transfer lanes functions.
* internal: because of the above, reworked the timer implementation to remove upvalue-dependency on lanes.core
* new: API lanes.timer_lane, to be able to operate on timer lane if need be
* improved: if a module is a full userdata, scan its metatable for function database population
* improved: on_state_create can be a Lua function
* changed: on_state_create is called after the base libraries are loaded
* package[loaders|searchers] is no longer transfered as function naming depends on slot order
* internal: changed separator from '.' to '/' in lookup databases to be able to distinguish search levels and dot coming from module names
* added some mode debug spew
* updated tests to reflect the above changes

* 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

Fixes an error when requiring lanes with active timers after having required "luarocks.loader" (issue #42).

* 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

- 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
