Improve vnet(4) to work better in busy conditions. No longer limit the ifq size to a low number, increase the slots on the DMA Ring a bit and abstract the VNET buffer size into a define. Enqueue packets on the ring but mark the initial packet ready at the end. This way the other ldom is not able to rush ahead and overconsume packets. The dring indexes are passed between ldoms and can get out of sync with causes the TX ring to stall. Tested by myself and jan@ OK kettenis@ jan@ kn@

Remove vestigial bits of 32-bit binaries support; drop the `64' suffix in struct names when the matching `32' flavour got removed.

Aggressively randomize the location of the stack on all 64-bit architectures except alpha. This will put the stack at a random location in the upper 1/4th of the userland virtual address space providing up to 26 additional bits of randomness in the address. Skip alpha for now since it currently puts the stack at a (for a 64-bit architecture) very low address. Skip 32-bit architectures for now as well since those have a much smaller virtual address space and we need more time to figure out what a safe amount of extra randomizations is. These architectures will continue to use a mildly randomized stack address through the existing stackgap random mechanism. We will revisit this after 7.3 is released.

_C_LABEL() and _ASM_LABEL() are no longer useful in the "everything is ELF" world. Eliminate use of them in amd64, arm64, armv7, i386, macppc, mips64, and sparc64 code.

Introduce the KEEPKERNELS variable: if this is set either in mk.conf or the environment, 'make cleandir' does not descend into kernel build directories. Thus, kernel object files survive 'make build' on slower architectures.
