* Implement __zipos_dup Makes ZiposHandle reference-counted by an `rc` field in a union with its freelist `next` pointer. The functions `__zipos_free` and `__zipos_keep` function as incref/decref for it. Adds `__zipos_postdup` to fix metadata on file descriptors after dup-like operations, and adds zipos support to `sys_dup_nt` + `sys_close_nt`. * Remove noop __zipos_postdup rc is never a zipos file because it is always a previously unused file descriptor. fd is never a zipos file because that case has been handled above by __zipos_fcntl. |
