timecounter kernels and non timecounter kernel co-exist

e8092c77bc Fix an integer overflow that prevented saving cores from machines with 
more than 2GB of RAM.

"dumpsize" in the on-disk core header is in pages, but, unfortunately,
c.size in our kcore format is an unsigned 32-bit int, gross.

We sleaze it, using a 64-bit int internally here and handing it to
libkvm as a *signed* 32-bit int.  Won't always work, but shouldn't be
broken any worse than it is now, and sometimes work better.

We must fix the kcore format and libkvm.

99319b80db Give a 60 day leeway instead of a week when judging if the dumptime is valid. 
7 days is too short when you are debugging time problems.

fa5157d9fb explicitly set the default compression level to 1 (from the implicit 6), 
because it's significantly faster and doesn't use that much more disk space.

fd08f59ac0 Add "-Z level" to control the compression level that -z uses (which 
defaults to -Z 6).  Depending on the relative speed of the CPU
versus disk, "-zZ1" might be faster than no compression at all.

1bb8e47f65 Make option flag variables static. This avoids a conflict between 
'int compress' in savecore.c and the function 'compress' in libz.
Gnu ld 2.10 (with BFD 2.10) used on sparc64 warns this conflict
(symbol "compress" changed size).

e7fe5f1380 Fix argument handling, which was pretty broken. 
If sysctl supports it, try to get the kernel name with CPU_BOOTED_KERNEL.

Adapt some error messages to the correct kernel name.
