Copy stable/9 to releng/9.3 as part of the 9.3-RELEASE cycle.

Merge r254263:

Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI
command register. The lazy BAR allocation code in FreeBSD sometimes
disables this bit when it detects a range conflict, and will re-enable
it on demand when a driver allocates the BAR. Thus, the bit is no longer
a reliable indication of capability, and should not be checked. This
results in the elimination of a lot of code from drivers, and also gives
the opportunity to simplify a lot of drivers to use a helper API to set
the busmaster enable bit.

This changes fixes some recent reports of disk controllers and their
associated drives/enclosures disappearing during boot.

Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.

The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

PR: kern/110662
MFC after: 3 days

Overhaul driver/subsystem api's:
o make all crypto drivers have a device_t; pseudo drivers like the s/w
crypto driver synthesize one
o change the api between the crypto subsystem and drivers to use kobj;
cryptodev_if.m defines this api
o use the fact that all crypto drivers now have a device_t to add support
for specifying which of several potential devices to use when doing
crypto operations
o add new ioctls that allow user apps to select a specific crypto device
to use (previous ioctls maintained for compatibility)
o overhaul crypto subsystem code to eliminate lots of cruft and hide
implementation details from drivers
o bring in numerous fixes from Michale Richardson/hifn; mostly for
795x parts
o add an optional mechanism for mmap'ing the hifn 795x public key h/w
to user space for use by openssl (not enabled by default)
o update crypto test tools to use new ioctl's and add cmd line options
to specify a device to use for tests

These changes will also enable much future work on improving the core
crypto subsystem; including proper load balancing and interposing code
between the core and drivers to dispatch small operations to the s/w
driver as appropriate.

These changes were instigated by the work of Michael Richardson.

Use newly added functions to simplify the code.

Use defines from cryptodev.h.

- Remove HMAC_BLOCK_LEN, it serves no purpose.
- Use defines of used algorithm instead of HMAC_BLOCK_LEN.

Add support for the CRD_F_KEY_EXPLICIT flag for both encryption and
authentication operations.

Unfortunately I've no hardware, so I only compiled-tested it.

Fix HMACs handling with uio's by not using crp_mac for storing calculated
HMAC. crp_mac is going to be removed.

Honor cri_mlen value.

Compile-tested: safe(4)

Since DELAY() was moved, most <machine/clock.h> #includes have been
unnecessary.

safe(4) doesn't support explicitly provided keys. Return an error instead
of encrypting/decrypting data with a wrong key.

Use BUS_PROBE_DEFAULT in preference to 0 and BUS_PROBE_LOW_PRIORITY in
preference to some random negative number to allow other drivers a

Compile on amd64. (pointer/int mismatches and printf int vs long )

Prefer new location of pci include files (which have only been in the
tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.

Change instances of callout_init that specify MPSAFE behaviour to
use CALLOUT_MPSAFE instead of "1" for the second parameter. This
does not change the behaviour; it just makes the intent more clear.

o add missing {}'s that to safe_dmamap_uniform that caused extraneous copies
for partly-aligned operations through /dev/crypto (unlikely)
o add missing case in iov code that never showed up because of the above bug
