The size field in the XENMEM_add_to_physmap_range is an uint16_t, and the
privcmd driver was doing an implicit truncation of an int into an uint16_t
when filling the hypercall parameters.
Fix this by adding a loop and making sure privcmd splits ioctl request into
2^16 chunks when issuing the hypercalls.

Although usually small, values produced by nitems() are unsigned.
Unsign inxdeing variables related to nitems() macros to avoid
signed vs. unsigned comparisons.
Although usually small, values produced by nitems() are unsigned.
By unsigning the corresponding indexes we avoid signed vs unsigned
comparisons. This may have some effect on performance, although given the
small sizes the effect will not be perceivable and it makes the code
clearer.

Respect the style of the changed files: one uses u_int while the other
uses "unsigned int".

PCI-express HotPlug support is implemented via bits in the slot
registers of the PCI-express capability of the downstream port along
with an interrupt that triggers when bits in the slot status register
change.
This is implemented for FreeBSD by adding HotPlug support to the
PCI-PCI bridge driver which attaches to the virtual PCI-PCI bridges
representing downstream ports on HotPlug slots. The PCI-PCI bridge
driver registers an interrupt handler to receive HotPlug events. It
also uses the slot registers to determine the current HotPlug state
and drive an internal HotPlug state machine. For simplicty of
implementation, the PCI-PCI bridge device detaches and deletes the
child PCI device when a card is removed from a slot and creates and
attaches a PCI child device when a card is inserted into the slot.
The PCI-PCI bridge driver provides a bus_child_present which claims
that child devices are present on HotPlug-capable slots only when a
card is inserted. Rather than requiring a timeout in the RC for
config accesses to not-present children, the pcib_read/write_config
methods fail all requests when a card is not present (or not yet
ready).
These changes include support for various optional HotPlug
capabilities such as a power controller, mechanical latch,
electro-mechanical interlock, indicators, and an attention button.
It also includes support for devices which require waiting for
command completion events before initiating a subsequent HotPlug
command. However, it has only been tested on ExpressCard systems
which support surprise removal and have none of these optional
capabilities.
PCI-express HotPlug support is conditional on the PCI_HP option
which is enabled by default on arm64, x86, and powerpc.

As mentioned in the Makefile there's an "atrocious" hack to generate a
different version of Options.inc.h, depending on the library being
built.
Remove the catch-all else case and limit it to specific libraries, so
that we don't accidentally use the Options.inc.h from clangdriver if a
future libary also uses Options.inc.h.

- While here, move a few more things out of _bitset.h and _cpuset.h to
bitset.h and cpuset.h, respectively. The only things left in
