was caused by upstream libc++ commit r194536, which aimed to make the
headers more standards-compliant, by making std::pair's copy constructor
trivial. Unfortunately, this could cause certain C++ applications using
shared libraries built against the previous version of libc++ to crash.
Fix the ABI incompatibility by making std::pair's copy constructor
non-trivial again.
Please note: Any C++ applications or shared libraries built with libc++
between r261283 and this revision should be recompiled.

I/O windows, the default is to preserve the firmware-assigned resources.
PCI bus numbers are only managed if NEW_PCIB is enabled and the architecture
defines a PCI_RES_BUS resource type.
- Add a helper API to create top-level PCI bus resource managers for each
PCI domain/segment. Host-PCI bridge drivers use this API to allocate
bus numbers from their associated domain.
- Change the PCI bus and CardBus drivers to allocate a bus resource for
their bus number from the parent PCI bridge device.
- Change the PCI-PCI and PCI-CardBus bridge drivers to allocate the
full range of bus numbers from secbus to subbus from their parent bridge.
The drivers also always program their primary bus register. The bridge
drivers also support growing their bus range by extending the bus resource
and updating subbus to match the larger range.
- Add support for managing PCI bus resources to the Host-PCI bridge drivers
used for amd64 and i386 (acpi_pcib, mptable_pcib, legacy_pcib, and qpi_pcib).
- Define a PCI_RES_BUS resource type for amd64 and i386.

routine, now a platform can provide a pointer to an early_putc() routine
which is used instead of cn_putc(). Control can be handed off from early
printf support to standard console support by NULLing out the pointer
during standard console init.
This leverages all the existing error reporting that uses printf calls,
such as panic() which can now be usefully employed even in early
platform init code (useful at least to those who maintain that code and
build kernels with EARLY_PRINTF defined).
