* Bumped version to 3.9.3
* new exposed variable linda.null that exposes the internal NIL_SENTINEL
marker
* linda:send() interprets send key linda.null as authorization to
silently send a single nil when not provided with anything to send
(useful when sending results of a function that can return nothing)

* bumped version to 3.9.2
* Internal rework: the whole Lanes engine now works "per universe" to
allow concurrent Lanes execution in more than one embedded master state
* this universe is a full userdata created in the master state,
selfdestruct_gc is the __gc for this userdata
* most of what was initialized only once is now per-universe
* Fixed potential crashes at desinit if problems occur during keeper
states initialisation
* Fixed require() not always serialized properly
* Raise an error instead of crashing on deep userdata prelude memory
allocation failure
* Added forgotten mutex desinitialisation at universe shutdown

* bumped version to 3.9.1
* keeper array is allocated with master state's alloc function instead
of malloc()/free()
* prevent application crash when specifying a very large number of
keepers in the configuration options
* removed some keeper desinit legacy dead code
* any error occuring during one-time inits is raised outside the
one-time mutex protected code region

* bumped version to 3.8.0
* linda:set() accepts multiple values to set in the specified slot
* linda:get() accepts an optional count to peek several values at once
* nil values are now converted just as in send()/receive()

* 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

Lanes, and send over native functions a bit faster as well
* Lanes no longer has to internally require modules inside the keeper
states because they no longer need a lookup database. the lookup name is
stored as-is and actually converted in the destination state
*
optimisation: bypass cache when sending native functions over
* removed
all the KEEPER_MODEL_LUA code, as it can no longer work anyway

* 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

* 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

* keeper internals implemented in C instead of Lua for better performances
* fixed arguments checks in linda:limit() and linda:set()

* added support for an on_state_create callback called to load custom functions in a state in addition to the base libraries

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
