[ANN] luaposix 34.0.2 released

["Gary V. Vaughan" <gary@...>]

A library binding various POSIX APIs. POSIX is the IEEE Portable 
Operating System Interface standard. luaposix is based on lposix.

I am happy to announce release 34.0.2 of luaposix.  In addition to the 
some small bug fixes, this release is somewhat smaller now that it 
optionally uses https://github.com/gvvaughan/typecheck for consistent 
argument type errors in Lua functions instead of its own version of the 
same, and relies on https://github.com/lua-stdlib/normalize for easier 
portability of Lua code.

If you have moved to the new low-level APIs, and don't rely on the Lua 
backwards compatibility layer and convenience functions, you can safely 
omit those dependencies and use the C layer only.

luaposix's home page is at https://github.com/luaposix/luaposix/, with 
documentation at https://luaposix.github.io/luaposix.

## Noteworthy changes in release 34.0.2 (2018-02-17) [stable]

### Incompatible Changes

  - `require 'posix'` (or any of its submodules) always returns a
    populated module table, but no longer sets `_G.posix` or any other
    global symbol on Lua 5.1 (including LuaJIT).  If you were relying
    on this behaviour, please change your require statements to an
    assignment:

    local posix = require 'posix'

### Bugs Fixed

  - `posix.sys.wait.wait` returns `<childpid>, "running"` when the
    child has not exited yet, and `wait` was called with `WNOHANG` set. 


  - specs don't fail on valid -1 return values from `posix.sysconf`.

  - loading posix (or any of its submodules) no longer leaks symbols
    into the global namespace on Lua 5.1 (including LuaJIT).
