In order for redirection to work properly when redirecting to an emulated
XHCI controller, the usb-redir-host must support both
usb_redir_cap_ep_info_max_packet_size and usb_redir_cap_64bits_ids,
reject any devices redirected to an XHCI controller when these are not
supported.

The shadow copy only serves as an extra check (besides the packet-id) to
ensure the packet we get back is a reply to the packet we think it is.
This check has never triggered in all the time usb-redir is in use now,
and since the verified data in the returned packet-header is not used
otherwise, removing the check does not open any possibilities for the
usbredirhost to confuse us.

There is no need for this, and doing so means that a backend trying to
write immediately after an open event will see qemu_chr_be_can_write
returning 0, which not all backends handle well as there is no wakeup
mechanism to detect when the frontend does become writable.

USB_RET_NAK is not a valid response for async handled packets (and will
trigger an assert as such).
Also drop the warning when receiving a status of cancelled for packets not
cancelled by qemu itself, this can happen when a device gets unredirected
by the usbredir-host while transfers are pending.

Since my previous comment said "Should never happen", I tried changing the

Currently each time we try to execute a NAK-ed packet we redo
ehci_init_transfer, and usb_packet_map, re-allocing (without freeing) the
sg list every time.
This patch fixes this, it does this by introducing another async state, so
that we also properly cleanup a NAK-ed packet on cancel.

This reverts commit 9bc3a3a216e2689bfcdd36c3e079333bbdbf3ba0, which got
added to fix an issue where the real, underlying cause was not stopping
the ep queue on an error.
Now that the underlying cause is fixed by the "usb: Halt ep queue and
cancel pending packets on a packet error" patch, the "don't flush" fix
is no longer needed.
Not only is it not needed, it causes us to see cancellations (unlinks)
done by the Linux EHCI driver too late, which in combination with the new
usb-core packet-id generation where qtd addresses are used as ids, causes
duplicate ids for in flight packets.

If an (emulated) usb-device tries to write more data to a packet then
its iov len, this will trigger an assert in usb_packet_copy(), and if
a driver somehow circumvents that check and writes more data to the
iov then there is space, we have a much bigger problem then not correctly
reporting babble to the guest.
In practice babble will only happen with (real) redirected devices, and there
both the usb-host os and the qemu usb-device code already check for it.

The qemu-img, qemu-nbd and qemu-io tools are built conditionally
based on whether any softmmu target is enabled. These are useful
self-contained tools which can be used in many other scenarios.
Add new --enable-tools/--disable-tools args to configure to allow
the user to explicitly turn on / off their build. The default
behaviour is now to build these tools are all times, regardless
of whether any softmmu target is enabled

This patch makes rtc_set_time and rtc_set_cmos work without reading
s->current_tm. In the case of rtc_set_time I introduce a new
function that retrieves the time and stores into a given struct tm
(not hard-coded to s->current_tm). In the case of rtc_set_cmos, the
current time is similarly taken from a struct tm rather than
s->current_tm.

Calculate guest RTC based on the time of the last update, instead of
using timers. The formula is
(base_rtc + guest_time_now - guest_time_last_update + offset)
Base_rtc is the RTC value when the RTC was last updated.
Guest_time_now is the guest time when the access happens.
Guest_time_last_update was the guest time when the RTC was last updated.
Offset is used when divider reset happens or the set bit is toggled.
The timer is kept in order to signal interrupts, but it only needs to
run when either UF or AF is cleared. When the bits are both set, the
timer does not run.
UIP is now synthesized when reading register A. If the timer is not set,
or if there is more than one second before it (as is the case at the
end of this series), the leading edge of UIP is computed and the rising
edge occurs 220us later. If the update timer occurs within one second,
however, the rising edge of the AF and UF bits should coincide withe
the falling edge of UIP. We do not know exactly when this will happen
because there could be delays in the servicing of the timer. Hence, in
this case reading register A only computes for the rising edge of UIP,
and latches the bit until the timer is fired and clears it.

Commit 7b93fadf3a38d1ed65ea5536a52efc2772c6e3b8 "Add basic version
of bridge helper" put the bridge helper executable into a fixed
${prefix}/libexec/ location, instead of using ${libexecdir} for
this. At the same time, --libexecdir is being happily ignored
by ./configure. Even more, the same patch sets unused $libexecdir
variable in the generated config-host.mak, and uses fixed string
(\${prefix}/libexecdir) for the bridge helper binary.
Fix this braindamage by introducing $libexecdir variable, using
it for the bridge helper binary, and recognizing --libexecdir.
This patch is applicable to stable-1.1.
