PR/55777: Ruslan Nikolaev: use MIN() from <sys/param.h> instead of min()

Round of uvm.h cleanup.

The poorly named uvm.h is generally supposed to be for uvm-internal
users only.

- Narrow it to files that actually need it -- mostly files that need
  to query whether curlwp is the pagedaemon, which should maybe be
  exposed by an external header.

- Use uvm_extern.h where feasible and uvm_*.h for things not exposed
  by it.  We should split up uvm_extern.h but this will serve for now
  to reduce the uvm.h dependencies.

- Use uvm_stat.h and #ifdef UVMHIST uvm.h for files that use
  UVMHIST(ubchist), since ubchist is declared in uvm.h but the
  reference evaporates if UVMHIST is not defined, so we reduce header
  file dependencies.

- Make uvm_device.h and uvm_swap.h independently includable while
  here.

Add a "userfeature" definition for iospace.  I/O space is supported if
that flag is given and calling the init routine succeeds (and we're on
x86, which we probably need to be on anyway for this PCI component to
currently be supported).

Also, some adjustments to make things between flags consistent, namely
deprecate the Makefile variable RUMP_PCI_IOSPACE and don't require
userfeature.h to map 1:1 to the interfaces.

Includes contributions from Robert Millan.

* make it possible for rumpcomp_pci_intr_establish() to know which
  device it's establishing the interrupt for
* make it possible to implement bus_dmamem_map() properly

remove obfuscation macros

Add a rump kernel component for the PCI bus.  It works both in Xen DomU
(via Xen's PCI passthrough) and Linux userspace (via uio_pci_generic).
