Avoid permanently disabled QEMU monitor when UNIX migration fails
If a UNIX migration command is attempt to a UNIX socket which does
not exist, then the monitor is suspended, but never resumed. This
prevents any further use of the monitor
* migration-unix.c: Only call migrate_fd_monitor_suspend() once
connected to the UNIX socket.

qdev: Separate USB product description from qdev name
Using the qdev name for the product description makes for inconvenient
qdev names.
Put the product description in new USBDeviceInfo member product_desc.
Make usb_qdev_init() use it. No user or guest visible change, since
the value is still the same.

fix rtc-td-hack on host without high-res timers
On hosts without high-res timers it is impossible to inject rtc interrupt
faster then 1kHz. Windows sometimes configures RTC to generate 1kHz
interrupts, so we can't inject missed interrupts when running on such
hosts. Always injecting an interrupt on REG_C read is also not an option
since Windows wait for REG_C to become zero with interrupt disabled
during boot. This patch uses mixed approach: accelerate timer + inject
up to 1000 interrupts on REG_C read.

migrating between hosts which have different features
might break silently, if the migration destination

Prevent this from happening by comparing acked feature

Do not abort on qemu_malloc(0) in production builds
qemu_malloc() does not allow size=0 to be passed in and aborts on this behavior.
Unfortunately, there is good reason to believe that within qemu, there are a
number of, so far, undetected places that assume size=0 can be safely passed.
Since we do not want to abort unnecessarily in production builds, return
qemu_malloc(1) whenever the version file indicates that this is a production
build.
Instruct make to remove any rule target on error. This prevetns
situation where there was an error during build but generated file still
stays behind.
