sfxge(4): add TLV item manipulation functions to common code
Add creation, deletion and checksumming operations to the private copy of
TLV functions in the common code. Functions added in preparation for V3
licensing support, as licensing keys are stored in the TLV format. Missing
support for multiple segment partitions added. Annotations for Windows code
analysis also updated.

[siba] migrate siba.c to siba_mips.c
Turns out that ye olde siba.c is /just/ the siba mips code (used by
the initial SENTRY5 port. However, I don't think it was ever
finished enough to be useful, and I do have this nagging feeling
that we'll eventually replace it with the bhnd code.
But, since bhnd(4) introduced siba.c too, we ended up with a
source file name clash, and that broke the SENTRY5 build.
It /looks/ like this is the only place siba.c / device siba is
used.

the bio to a pristine state should you wish to re-use it for another

Don't store generated firmware object files in the source directory.
Trim the leading directory of a firmware source file from the resulting
target object file name so the object file is stored in the object
directory. Previously, using 'FIRMWS= /path/to/fw.bin:fw.bin' would
store the generated 'fw.bin.fwo' file in the /path/to directory. Now
it stores it in the object directory of the kernel module being built.

Add (commented) 'vital' flag to the runtime packages. Support for
it is expected in pkg-1.8.0, which will cause 'pkg del -afy' to not
destroy a system by forcefully removing everything.
As there are valid use cases for doing such (test jails, for example),
it will be overrideable.
In addition, ensure /dev and /tmp exist, as /dev is not created by
default currently, and pkg(8) requires /tmp to exist, which is also
not created by default.
This needs to be moved to the clibs package, since runtime depends on
that package, however I need to first verify that it will work as it
is expected.

Add a new bus method to fetch device-specific CPU sets.
bus_get_cpus() returns a specified set of CPUs for a device. It accepts
an enum for the second parameter that indicates the type of cpuset to
request. Currently two valus are supported:
- LOCAL_CPUS (on x86 this returns all the CPUs in the package closest to
the device when DEVICE_NUMA is enabled)
- INTR_CPUS (like LOCAL_CPUS but only returns 1 SMT thread for each core)
For systems that do not support NUMA (or if it is not enabled in the kernel
config), LOCAL_CPUS fails with EINVAL. INTR_CPUS is mapped to 'all_cpus'
by default. The idea is that INTR_CPUS should always return a valid set.
Device drivers which want to use per-CPU interrupts should start using
INTR_CPUS instead of simply assigning interrupts to all available CPUs.
In the future we may wish to add tunables to control the policy of
INTR_CPUS (e.g. should it be local-only or global, should it ignore
SMT threads or not).
The x86 nexus driver exposes the internal set of interrupt CPUs from the
the x86 interrupt code via INTR_CPUS.
The ACPI bus driver and PCI bridge drivers use _PXM to return a suitable
LOCAL_CPUS set when _PXM exists and DEVICE_NUMA is enabled. They also and
the global INTR_CPUS set from the nexus driver with the per-domain set from
_PXM to generate a local INTR_CPUS set for child devices.
Compared to the r298933, this version uses 'struct _cpuset' in
<sys/bus.h> instead of 'cpuset_t' to avoid requiring <sys/param.h>
(<sys/_cpuset.h> still requires <sys/param.h> for MAXCPU even though
<sys/_bitset.h> does not after recent changes).

Simplify redundant malloc'ing in sed -e.
When encountering an -e argument, sed currently mallocs a string to COPY
the optarg -- with '\n' appended. The appendage does not seem necessary --
indeed, the same call to add_compunit processing the sole command (given

appending newline.
This matches what is done in other BSDs.

Use DDP to implement zerocopy TCP receive with aio_read().
Chelsio's TCP offload engine supports direct DMA of received TCP payload
into wired user buffers. This feature is known as Direct-Data Placement.
However, to scale well the adapter needs to prepare buffers for DDP
before data arrives. aio_read() is more amenable to this requirement than
read() as applications often call read() only after data is available in
the socket buffer.
When DDP is enabled, TOE sockets use the recently added pru_aio_queue
protocol hook to claim aio_read(2) requests instead of letting them use
the default AIO socket logic. The DDP feature supports scheduling DMA
to two buffers at a time so that the second buffer is ready for use
after the first buffer is filled. The aio/DDP code optimizes the case
of an application ping-ponging between two buffers (similar to the
zero-copy bpf(4) code) by keeping the two most recently used AIO buffers
wired. If a buffer is reused, the aio/DDP code is able to reuse the
vm_page_t array as well as page pod mappings (a kind of MMU mapping the
Chelsio NIC uses to describe user buffers). The generation of the
vmspace of the calling process is used in conjunction with the user
buffer's address and length to determine if a user buffer matches a
previously used buffer. If an application queues a buffer for AIO that
does not match a previously used buffer then the least recently used
buffer is unwired before the new buffer is wired. This ensures that no
more than two user buffers per socket are ever wired.
Note that this feature is best suited to applications sending a steady
stream of data vs short bursts of traffic.

Restore name=value format of PCI location strings.
When devctl was added, the location string for PCI devices was changed to
use the PCI "selector" that pciconf and devctl accept. However, devd
assumes that location strings are formatted as a list of name=value pairs.
As a result, devd is no longer parsing any of the values out of PCI
device events. Restore the previous format of the PCI location strings
to restore the location and slot keywords in case any devd scripts are
using this. Add the "selector" as a new 'dbsf' location variable.
