  1. Add O_CLOEXEC to open calls. 

    This prevents file descriptors from leaking to child processes.

When compiled for older (pre-2.6.23) kernels which lack support for
O_CLOEXEC there is no change in behavior.  With newer kernels, child
processes will no longer inherit leveldb's file handles, which
reduces the changes of accidentally corrupting the database.

Fixes google#623
