The other integer request types which shutdown supported are not
useful. Specifically:
* "suspend" is not usable via this interface since it requires other
scaffolding, libxl_domain_suspend provides this already.
* "halt" is the same as "poweroff".
* "crash" is unused and at least Linux does not implement it. If a user
steps forward then libxl_domain_crash is trivial to add.

oxenstored is an ocaml implementation of the xenstore daemon. It is faster,
more scalable and more reliable than the C xenstored.
In particular the transaction model in oxenstored does not involve taking a
complete copy of the database and aborting on any (even non-conflicting) other
change.
There is a paper on the design and implementation of oxenstored at
http://gazagnaire.org/pub/GH09.pdf which includes a performance evaluation and
comparison with the C daemon etc.

The only cases where we might end up emulating fsincos (as any other
x87 operations without memory operands) are
- when a HVM guest is in real mode (not applicable on AMD)
- between two half page table updates in PAE mode (unlikely, and not
doing the emulation here does affect only performance, not
correctness)
- when a guest maliciously (or erroneously) modifies an (MMIO or page
table update) instruction under emulation (unspecified behavior)
Hence, in order to avoid the erratum to cause harm to the entire host,
don't emulate fsincos on the affected AMD CPU families.

Previous an unknown operation would be decoded as a Not_found exception which
would bubble all the way up to the try ... with surrounding the call to
main_loop where it would be logged and ignored.
This would leave the guest hanging waiting for a response to the invalid
request.
Instead introduce a specific "Invalid" operation. Higher level functionality,
such as Process.process_packet, already handles operations which are not
understood with an error reply due to the final wildcard entry in
Process.function_of_type but explicitly handle Invalid this way to make it
clear what is going on.

GCC and C99 allow declarations to be mixed with code. This is a good
idea because:
* It allows variables to be more often initialised as they are
declared, thus reducing the occurrence of uninitialised variable
errors.
* Certain alloca-like constructs (arrays allocated at runtime on the
stack) can more often be written without a spurious { } block.
Such blocks are confusing to read.
* It makes it easier to write and use macros which declare and
initialise formulaic variables and do other function setup code,
because there is no need to worry that such macros might be
incompatible with each other or have strict ordering constraints.

else who is also using another version of queue.h.

[L]GPL-compatible licence, so there is no need to change our COPYING.
Although FreeBSD's queue.3 still contains the advertising clause, this
