convert the (still disabled) 'direct write' for pipes to use the experimental PMAP_DIRECT if available; the direct code paths now survive longer than the pmap_enter() variant, but still triggers panic during build.sh tools run; remove some obsolete sysctls add some XXXs to mark places which need attention to make this more stable Note: the loan case is now actually significantly slower than the non-loan case on MP systems, due to synchronous IPIs triggered by marking the page read-only by uvm_loan(); this is being discussed in the email thread https://mail-index.netbsd.org/tech-kern/2018/05/21/msg023441.html that is basically the same issue due to which loaning was disabled for sosend()
