* Make dev_name resolve symlinks before resolving the name.
- When symlinks are not resolved first, you will get an error on startup when
using path in /dev/disk/by-id, for example, in diskiograph_*.
* Improve diskio device name resolution by always resolving symlinks.
- Any device path will be resolved of any symlinks before getting the usual
checks for labels et device name.
* Check if diskio device is really a block device, not only if it exists.
- Current check would succeed in case the device is a path, like when using
label: with an empty argument.
* don't use kvm_* calls, just sysctl (so no suid perm necessary)
* sysctls calls in general aren't thread safe, collapse callbacks
using same sysctls (specifically total/running procs and proc list
ones).
Some sysctls need two calls (first to get size of obj returned,
second to get object self); if different threads use this schema
on same sysctl, weird values are returned (first/second calls
sequence should be serialized).
In general it makes not much sense too having more threads that use
the same sysctl; just get info once and populate all data.
* add DragonFly specific extended uname string ($version in conky.conf)
with git version and signature
Todo:
- top process list logic is old style, use top.cc funcs.
- find a solution for cpu freq

I'm doing this because otherwise i'll will forget to add all those
std::'s and will lose a LOT of time finding the problems.
If you don't agree, undo this patch...
...but i hope you won't :)
