Allow more memory ranges in hibernate The previous limit of VM_PHYSSEG_MAX ranges (16) was proving too small for newer machines. This diff reorganizes the hibernate signature block to allow for 22 ranges by removing the kernel version comparison and replacing it with a SHA of several unique kernel features (the version string and several addresses of functions not inside the same .o). Reported by claudio@, who also helped fix some issues in the diff. Input from deraadt@ as well. Tested by myself and claudio on a variety of machines. Only compile tested on i386 as I have no more S4-capable i386 hardware anymore. ok claudio@

Rework piglet and pig allocation. Currently the piglet gets allocated deep down in the suspend path, where it is really hard to recover from allocation failure. So allocate the piglet early on in the suspend path. Also change the piglet and piglet allocation functions to use km_alloc(9) instead of doing pmemrange magic. This removes a bunch of code which, in the case of the piglet allocation, is broken since it results in a NULL pointer dereference. Also switch the piglet allocation to not wait. If we can't allocate 16MB of phys contig memory on a halfway modern machine we're almost certainly under a lot of memory pressure and we're better off not trying to hibernate anyway. ok mlarkin@

Add a magic number to the head of the signature block. Check for magic number match during signature block read during speculative unhibernate on boot. If the magic number matches but we have otherwise chosen to not unhibernate (due to kernel/memory mismatch), clear the signature block early to avoid accidentally trying to unhibernate on subsequent boots. This prevents accidental unhibernates and endless unhibernate/reboot cycles. Add a define for HIBERNATE_DEBUG for various debugging printfs (disabled by default). Finally, change some KASSERTs to warning printfs (they probably shouldn't have been KASSERTs in the first place). "looks good" deraadt@
