wrapper around rman_adjust_resource(). Include a generic implementation,
bus_generic_adjust_resource() which passes the request up to the parent
bus. There is currently no default implementation. A
bus_adjust_resource() wrapper is provided for use in drivers.
Specifically, these changes allow a resource to back a relocatable and
resizable resource such as the I/O window decoders in PCI-PCI bridges.
- rman_adjust_resource() can adjust the start and end address of an
existing resource. It only succeeds if the newly requested address
space is already free. It also supports shrinking a resource in
which case the freed space will be marked unallocated in the rman.
- rman_first_free_region() and rman_last_free_region() return the
start and end addresses for the first or last unallocated region in
an rman, respectively. This can be used to determine by how much
the resource backing an rman must be adjusted to accomodate an
allocation request that does not fit into the existing rman.
While here, document the rm_start and rm_end fields in struct rman,

media option generally should be used instead. Actually I think the lists
of media types should be removed from the manual pages of MAC drivers
altogether and users just pointed to the output of `ifconfig -m` instead;
even before r215297 there were several outdated descriptions, technically
it's wrong most of the time as not the MAC drivers support these media
types but actually the PHY drivers do and it generally doesn't make sense
to maintain these lists in every manual page of a driver as the media is
auto-detected.

* Recent versions of Autoconf use it a lot.
* Almost no software still wants to support systems that do not have

* In many other shells printf is already a builtin.

via the undocumented %builtin mechanism).

structures let us use bh_tstamp of same size on both 32-bit and 64-bit

platforms, size of BPF header does not change compared to bpf_hdr as its
members are already all 64-bit long. On 32-bit platforms, the size may
increase by 8 bytes. For backward compatibility, struct bpf_hdr with
struct timeval is still the default header unless new time stamp format is
