- Copy stable/10 (r259064) to releng/10.0 as part of the 10.0-RELEASE cycle. - Update __FreeBSD_version [1] - Set branch name to -RC1
[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so start releng/10.0 at '100' so the branch is started with a value ending in zero.

- Commit work from libprocstat project. These patches add support for runtime file and processes information retrieval from the running kernel via sysctl in the form of new library, libprocstat. The library also supports KVM backend for analyzing memory crash dumps. Both procstat(1) and fstat(1) utilities have been modified to take advantage of the library (as the bonus point the fstat(1) utility no longer need superuser privileges to operate), and the procstat(1) utility is now able to display information from memory dumps as well.
The newly introduced fuser(1) utility also uses this library and able to operate via sysctl and kvm backends.
The library is by no means complete (e.g. KVM backend is missing vnode name resolution routines, and there're no manpages for the library itself) so I plan to improve it further. I'm commiting it so it will get wider exposure and review.
We won't be able to MFC this work as it relies on changes in HEAD, which was introduced some time ago, that break kernel ABI. OTOH we may be able to merge the library with KVM backend if we really need it there.

Add a new type of VM object: OBJT_SG. An OBJT_SG object is very similar to a device pager (OBJT_DEVICE) object in that it uses fictitious pages to provide aliases to other memory addresses. The primary difference is that it uses an sglist(9) to determine the physical addresses for a given offset into the object instead of invoking the d_mmap() method in a device driver.

Do not segfault when procstat -f or procstat -v is called on a process not owned by the current user. If kinfo_getfile() or kinfo_getvmmap() return NULL, simply exit, and do not try and derefernce the memory.

Merge user/peter/kinfo branch as of r185547 into head.
This changes struct kinfo_filedesc and kinfo_vmentry such that they are same on both 32 and 64 bit platforms like i386/amd64 and won't require sysctl wrapping.
Two new OIDs are assigned. The old ones are available under COMPAT_FREEBSD7 - but it isn't that simple. The superceded interface was never actually released on 7.x.
The other main change is to pack the data passed to userland via the sysctl. kf_structsize and kve_structsize are reduced for the copyout. If you have a process with 100,000+ sockets open, the unpacked records require a 132MB+ copyout. With packing, it is "only" ~35MB. (Still seriously unpleasant, but not quite as devastating). A similar problem exists for the vmentry structure - have lots and lots of shared libraries and small mmaps and its copyout gets expensive too.
My immediate problem is valgrind. It traditionally achieves this functionality by parsing procfs output, in a packed format. Secondly, when tracing 32 bit binaries on amd64 under valgrind, it uses a cross compiled 32 bit binary which ran directly into the differing data structures in 32 vs 64 bit mode. (valgrind uses this to track file descriptor operations and this therefore affected every single 32 bit binary)
I've added two utility functions to libutil to unpack the structures into a fixed record length and to make it a little more convenient to use.

WARNS fixes: mainly constness and avoid comparing signed with unsigned by making array indicies unsigned. Also note one or two unused parameters.

Add procstat(1), a process inspection utility. This provides both some of the missing functionality from procfs(4) and new functionality for monitoring and debugging specific processes. procstat(1) operates in the following modes:
-b Display binary information for the process. -c Display command line arguments for the process. -f Display file descriptor information for the process. -k Display the stacks of kernel threads in the process. -s Display security credential information for the process. -t Display thread information for the process. -v Display virtual memory mappings for the process.
Further revision and modes are expected.
