e711c6f0d1 Unlock the malloc() locks in the child process after fork(). This gives
us working malloc in the fork child of the multithreaded process.

Although POSIX requires that only async-signal safe functions shall be
operable after fork in multithreaded process, not having malloc lower
the quality of our implementation.

5157f46024 Format the output of -itv for real. In particular:
* Lookup uname/gname if not provided by the archive (I copied the
   uname/gname lookup cache from bsdtar)
 * Format device number instead of size for device nodes
 * Format date.

There's still a few improvements that I could copy from
bsdtar, especially the locale-aware safe_fprintf() code
and the locale-aware setup for day_first date formatting.
(And, of course, I need to think through a clean way to
push this stuff down into libarchive.)

Thanks to Peter Wemm for reminding me of this overlooked TODO item.

5af3583731 When deciding which characters (of a filename, for instance)
are safe to print, try to take into account the current locale.
This iterates over output strings using mbtowc() to identify
multi-byte sequences.  If iswprint() claims the corresponding
wide character is printable, the original bytes are passed
through.  Otherwise, we expand characters into C-style
\-escape sequences.

413628a7e3 MFp4:
Bring in updated jail support from bz_jail branch.

This enhances the current jail implementation to permit multiple
addresses per jail. In addtion to IPv4, IPv6 is supported as well.
Due to updated checks it is even possible to have jails without
an IP address at all, which basically gives one a chroot with
restricted process view, no networking,..

SCTP support was updated and supports IPv6 in jails as well.

Cpuset support permits jails to be bound to specific processor
sets after creation.

Jails can have an unrestricted (no duplicate protection, etc.) name
in addition to the hostname. The jail name cannot be changed from
within a jail and is considered to be used for management purposes
or as audit-token in the future.

DDB 'show jails' command was added to aid debugging.

Proper compat support permits 32bit jail binaries to be used on 64bit
systems to manage jails. Also backward compatibility was preserved where
possible: for jail v1 syscalls, as well as with user space management
utilities.

Both jail as well as prison version were updated for the new features.
A gap was intentionally left as the intermediate versions had been
used by various patches floating around the last years.

Bump __FreeBSD_version for the afore mentioned and in kernel changes.

Special thanks to:
- Pawel Jakub Dawidek (pjd) for his multi-IPv4 patches
  and Olivier Houchard (cognet) for initial single-IPv6 patches.
- Jeff Roberson (jeff) and Randall Stewart (rrs) for their
  help, ideas and review on cpuset and SCTP support.
- Robert Watson (rwatson) for lots and lots of help, discussions,
  suggestions and review of most of the patch at various stages.
- John Baldwin (jhb) for his help.
- Simon L. Nielsen (simon) as early adopter testing changes
  on cluster machines as well as all the testers and people
  who provided feedback the last months on freebsd-jail and
  other channels.
- My employer, CK Software GmbH, for the support so I could work on this.

6179164448 In the nfsrv_fhtovp(), after the vfs_getvfs() function found the pointer
to the fs, but before a vnode on the fs is locked, unmount may free fs
structures, causing access to destroyed data and freed memory.

Introduce a vfs_busymp() function that looks up and busies found
fs while mountlist_mtx is held. Use it in nfsrv_fhtovp() and in the
implementation of the handle syscalls.

Two other uses of the vfs_getvfs() in the vfs_subr.c, namely in
sysctl_vfs_ctl and vfs_getnewfsid seems to be ok. In particular,
sysctl_vfs_ctl is protected by Giant by being a non-sleeping sysctl
handler, that prevents Giant-locked unmount code to interfere with it.

f02493cbbd Unhide declarations of network stack virtualization structs from

This change introduces some churn in #include ordering and nesting

In the next step this will allow us to instantiate the virtualization
container structures and switch from using global variables to their
"containerized" counterparts.

1cbae70533 Fix matching of message queues by name.
The mqfs_search() routine uses strncmp() to match message queue objects
by name. This is because it can be called from environments where the
file name is not null terminated (the VFS for example).

Unfortunately it doesn't compare the lengths of the message queue names,
which means if a system has "Queue12345", the name "Queue" will also
match.

I noticed this when a student of mine handed in an exercise using
message queues with names "Queue2" and "Queue".

cb5c4b10ba Add two rtld exported symbols, _rtld_atfork_pre and _rtld_atfork_post.
Threading library calls _pre before the fork, allowing the rtld to
lock itself to ensure that other threads of the process are out of
dynamic linker. _post releases the locks.

This allows the rtld to have consistent state in the child. Although
child may legitimately call only async-safe functions, the call may
need plt relocation resolution, and this requires working rtld.

0cfab8ddc1 - Add support for PMCs in Intel CPUs of Family 6, model 0xE (Core Solo
and Core Duo), models 0xF (Core2), model 0x17 (Core2Extreme) and
  model 0x1C (Atom).

  In these CPUs, the actual numbers, kinds and widths of PMCs present
  need to queried at run time.  Support for specific "architectural"
  events also needs to be queried at run time.

  Model 0xE CPUs support programmable PMCs, subsequent CPUs
  additionally support "fixed-function" counters.

- Use event names that are close to vendor documentation, taking in
  account that:
  - events with identical semantics on two or more CPUs in this family
    can have differing names in vendor documentation,
  - identical vendor event names may map to differing events across
    CPUs,
  - each type of CPU supports a different subset of measurable
    events.

  Fixed-function and programmable counters both use the same vendor
  names for events.  The use of a class name prefix ("iaf-" or
  "iap-" respectively) permits these to be distinguished.

- In libpmc, refactor pmc_name_of_event() into a public interface
  and an internal helper function, for use by log handling code.

- Minor code tweaks: staticize a global, freshen a few comments.
