Merge remote-tracking branch 'upstream/master'

* upstream/master:
  Fix warnings: unused variable
  Fix warning: C++ style comments are not allowed in ISO C90
  Set global "lfs" when opening module
  Bump version to 1.6.2 and set version via define in src/lfs.c to make it better visible
  Full Lua 5.2 compatibility and adherance to modules-create-no-globals
  fix build for Lua 5.2; version 1.6.1
  lfs.c: use Lua 5.2's own luaL_register
  luafilesystem 1.6.0
  Due to Android (and apparently Sun) not supporting getcwd(NULL, 0), I've changed to call to getcwd to specify a buffer and explicit size which successfully works around the problem. One minor performance advantage is that one less malloc/free is needed since the buffer is now created on the stack. Apparently, this was already changed in a prior commit I didn't see initially, but I think the use of an invented/arbitrary PATH_MAX is incorrect. Platforms should generally provide a constant for this and PATH_MAX itself is already defined on some systems like Linux which can cause collisions. This commit improves on those changes by leveraging the constants provided by the compiler/system.
  implements fake luaL_register in Lua 5.2+
