Simplify life a little for such a simple program.

b34fae62b6 Grab two syscall numbers. One is used to emulate functionality that linux
has in its procfs (do a readlink of /proc/self/fd/<nn> to find the pathname
that corresponds to a given file descriptor).  Valgrind-3.x needs this
functionality.  This is a placeholder only at this time.

fafadf82fa Set removable_route_flush to NO be default. It's clearly the wrong
thing to do in most (all?) cases and certainly should not be the default
now that we're running pccard_ether on all interface creates and

ec5f8c0e3a Clarify documentation of '-L' command line switch: the snapshot is
unlinked as soon as the dump starts (and removed when the dump is
completed, and the dump process exits). Previous wording was confusing
because users might expect the snapshot to be visible in the .snap
subdirectory while dump is running.

babdb5cd99 Remove unsafe use of asynchronous I/O (the SIGIO handler could cause
incorrect reentrant calls to the libc memory manager).

Add missing error handling:
  * for an incoming response with an incorrect tid;
  * for a failure to register the response RPC program,

Fix error handling for failure to malloc job descriptor (this needs to
be done before the transient RPC program is registered).

053be5b222 Move the setup of "diskless" /etc magic files from install_etc() to a
separate function which is called right after install_etc().  This makes
it simpler to (ab)use nanobsd.sh as a framework to build more normal
FreeBSD images where a normal /etc is used, since setup_nanobsd_etc()
can just be redefined.

4e96206d8a Add a new 'show sleepchain' ddb command similar to 'show lockchain' except
that it operates on lockmgr and sx locks.  This can be useful for tracking
down vnode deadlocks in VFS for example.  Note that this command is a bit
more fragile than 'show lockchain' as we have to poke around at the
wait channel of a thread to see if it points to either a struct lock or
a condition variable inside of a struct sx.  If td_wchan points to
something unmapped, then this command will terminate early due to a fault,
but no harm will be done.

e092be0121 - When spinning on a spin lock, if the debugger is active or we are in a

- If we panic due to spinning too long, print out a few more details
  including the pointer to the mutex in question and the tid of the owning
  thread.

ae769794c6 Use SYS_AUE_<syscallname> to include the appropriate audit event identifier
for syscalls in kld's, even when compiled into the kernel statically.
Note that since this hardcodes the SYS_ prefix SYSCALL_MODULE_HELPER() now
only works for native ABI system calls.  Those are the only ones that
used the macro anyway, and I chose to not require a second argument to the
macro to specify the prefix or audit event directly.

61e1e0725a - Remove unused sysvec variables from various syscalls.conf.
- Send the systrace_args files for all the compat ABIs to /dev/null for
  now.  Right now makesyscalls.sh generates a file with a hardcoded
  function name, so it wouldn't work for any of the ABIs anyway.  Probably
  the function name should be configurable via a 'systracename' variable
  and the functions should be stored in a function pointer in the sysvec
  structure.

3cbb1cf256 Add a new set of macros <prefix>_AUE_<syscallname> to sysproto.h that

a620e8e32b Make it a tad easier to base other encapsulation schemes on this driver
by restoring the ifv_proto field in the vlan softc and putting it to use
this time.  It's a good companion for ifv_encaplen, which has already been
used throughout this driver.

c8c91ce0a9 Rename 'show lockchain' to 'show locktree' and 'show threadchain' to
'show lockchain'.  The churn is because I'm about to add a new
'show sleepchain' similar to 'show lockchain' for sleep locks (lockmgr and
sx) and 'show threadchain' was a bit ambiguous as both commands show
a chain of thread dependencies, 'lockchain' is for non-sleepable locks
(mtx and rw) and 'sleepchain' is for sleepable locks.

d7e3bf9763 Ooops we need to include <machine/vmparam.h> to get the definition of
KERNBASE and VM_MAXUSER_ADDRESS.
Remove the useless include of opt_global.h, as noticed by netchild@ (the one
in arm/elf_trampoline.c is legit, because this file is compiled outside the
kernel, and doesn't use the standard CFLAGS).

ec2ba5d85d Add the linux 2.6.x stuff (not used by default!):
- TLS - complete
 - pid/tid mangling - complete
 - thread area - complete
 - futexes - complete with issues
 - clone() extension - complete with some possible minor issues
 - mq*/timer*/clock* stuff - complete but untested and the mq* stuff is
   disabled when not build as part of the kernel with native FreeBSD mq*
   support (module support for this will come later)

Tested with:
 - linux-firefox - works, tested
 - linux-opera - works, tested
 - linux-realplay - doesnt work, issue with futexes
 - linux-skype - doesnt work, issue with futexes
 - linux-rt2-demo - works, tested
 - linux-acroread - doesnt work, unknown reason (coredump) and sometimes
   issue with futexes
 - various unix utilities in linux-base-gentoo3 and linux-base-fc4:
   everything tried worked

On amd64 not everything is supported like on i386, the catchup is planned for
later when the remaining bugs in the new functions are fixed.

To test this new stuff, you have to run
	sysctl compat.linux.osrelease=2.6.16
to switch back use
	sysctl compat.linux.osrelease=2.4.2

Don't switch while running a linux program, strange things may or may not
happen.
