Fix 64 bits compilation warnings (issue #34)
rockspec for version 3.2.0
lanes version 3.2.0
* keeper internals implemented in C instead of Lua for better performances
* fixed arguments checks in linda:limit() and linda:set()
lanes version 3.2.0
* keeper internals implemented in C instead of Lua for better performances
* fixed arguments checks in linda:limit() and linda:set()
Fix ubuntu compilation errors

* missing inclusion of <stdint.h>
* use __min instead of min
Make *really* sure we build for all platforms :-)
rockspec for v3.3.0
version 3.3.0
   * 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.
fixed a bad forward declaration
code tweaks to enable building against win32-pthread on windows platforms.
not active by default, see threading.h.
minor internal changes
   * implemented set_debug_threadname() for pthread builds where possible
   * refactored linda __tostring and __concat
   * linda metatable's __metatable is a string instead of a boolean
removed fixed BUGS entries
version 3.4.0
   * 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
Commented out some obsolete code in CMakeLists
build fixes
Fixed a comment to match the code
Always set "decoda_name" global in a new Lane.
More informative messages on failed transfers.
Fixed thread name retrieval in main state.
Fixed the fix...
