2ca7463bc7 Properly handle suspend/resume events in the Xen device
framework.

Sponsored by:	BQ Internet

sys/xen/xenbus/xenbusb.c:
	o In xenbusb_resume(), publish the state transition of the
	  resuming device into XenbusStateIntiailising so that the
	  remote peer can see it.  Recording the state locally is
	  not sufficient to trigger a re-connect sequence.
	o In xenbusb_resume(), defer new-bus resume processing until
	  after the remote peer's XenStore address has been updated.
	  The drivers may need to refer to this information during
	  resume processing.

sys/xen/xenbus/xenbusb_back.c:
sys/xen/xenbus/xenbusb_front.c:
	Register xenbusb_resume() rather than bus_generic_resume()
	as the handler for device_resume events.

sys/xen/xenstore/xenstore.c:
	o Fix grammer in a comment.
	o In xs_suspend(), pass suspend events on to the child
	  devices (e.g. xenbusb_front/back, that are attached
	  to the XenStore.

750b5e3134 Restore the writing of the .bss sections of the dsos (not the main
executable) after r190885. The whole region for the dso is mmaped with
MAP_NOCORE flag, doing only mprotect(2) over .bss prevented it from
writing .bss to core files.

Revert the optimization of using mprotect(2) to establish .bss, overlap
the section with mmap(2).

8cdd0a8091 Remove RA timer on an interface with !IFF_UP actively after starting to send
clean-up RA messages for shutting down.  The RA timers could prevent the rtadvd
daemon from shutting down because ra_output() just ignored !IFF_UP interfaces
and TRANSITIVE->UNCONFIGURED state transition never happened due to it.

b38520f09c Fix long-standing thinko regarding maxproc accounting. Basically,
we were accounting the newly created process to its parent instead
of the child itself.  This caused problems later, when the child
changed its credentials - the per-uid, per-jail etc counters were
not properly updated, because the maxproc counter in the child
process was 0.

8451d0dd78 In order to maximize the re-usability of kernel code in user space this
patch modifies makesyscalls.sh to prefix all of the non-compatibility
calls (e.g. not linux_, freebsd32_) with sys_ and updates the kernel
entry points and all places in the code that use them. It also
fixes an additional name space collision between the kernel function
psignal and the libc function of the same name by renaming the kernel
psignal kern_psignal(). By introducing this change now we will ease future
MFCs that change syscalls.

a17e51c108 When resuming an HTTP download, we failed to verify that the range
returned by the server matched what we requested, and blindly appended
what we received to what we already had.  This could go two ways: if the
delivered offset was higher than expected, the local file would contain
duplicate data, while if it was lower than expected, there would be data
missing from the middle of the file.  Furthermore, if the transfer was
interrupted again, each subsequent attempt would compound the error.
Fix the first problem by restarting the transfer from scratch if there
is a gap, and the second by explicitly seeking to the correct location
in the local file so as to overwrite any duplicated data.
