- Consolidate duplicate SMBIOS table structure definitions in ipmi(4)

Fix test for double-nul characters that terminate the string table at

Rework the SMBIOS table walker to make it operate like other table walkers
and remove a buffer overflow:
- Remove the array of per-type dispatch functions. Instead, pass each
structure to a single callback. The callback should check the type of
each table entry to take appropriate action. This matches the behavior
of other table walkers such as for the MP Table and MADT.
- Don't attempt to save an array of string pointers for each structure
entry. Instead, just skip the strings. If this code is reused to
provide a generic SMBIOS table walker in the future we could provide
a method that looks up a specific string N for a given structure record
instead of pre-populating an array of pointers. This fixes a buffer
overflow for structure entries with more than 20 strings.

Merge from head up to r188941 (last revision before the USB stack switch)

Update the projects tree to a newer FreeBSD current.

- Change ichsmb(4) to follow the format of all the other smbus controllers
for slave addressing by using left-adjusted slave addresses (i.e.
xxxxxxx0b).
- Require the low bit of the slave address

- Change ichsmb(4) to follow the format of all the other smbus controllers
for slave addressing by using left-adjusted slave addresses (i.e.
xxxxxxx0b).
- Require the low bit of the slave address to always be zero in smb(4) to
help catch broken applications.
- Adjust some code in the IPMI driver to not convert the slave address for
SSIF to a right-adjusted address. I (or possibly ambrisko@) added this in
the past to (unknowingly) work around the bug in ichsmb(4).

Update __FreeBSD_version check for MFC of pmap_mapbios().

Map pmap_{un,}mapbios() to pmap_{un,}mapdev() on 6.x and earlier.

Update the ipmi(4) driver:
- Split out the communication protocols into their own files and use
a couple of function pointers in the softc that the commuication
protocols setup in their own attac

Update the ipmi(4) driver:
- Split out the communication protocols into their own files and use
a couple of function pointers in the softc that the commuication
protocols setup in their own attach routine.
- Add support for the SSIF interface (talking to IPMI over SMBus).
- Add an ACPI attachment.
- Add a PCI attachment that attaches to devices with the IPMI interface
subclass.
- Split the ISA attachment out into its own file: ipmi_isa.c.
- Change the code to probe the SMBIOS table for an IPMI entry to just use
pmap_mapbios() to map the table in rather than trying to setup a fake
resource on an isa device and then activating the resource to map in the
table.
- Make bus attachments leaner by adding attach functions for each
communication interface (ipmi_kcs_attach(), ipmi_smic_attach(), etc.)
that setup per-interface data.
- Formalize the model used by the driver to handle requests by adding an
explicit struct ipmi_request object that holds the state of a given
request and reply for the entire lifetime of the request. By bundling
the request into an object, it is easier to add retry logic to the various
communication backends (as well as eventually support BT mode which uses
a slightly different message format than KCS, SMIC, and SSIF).
- Add a per-softc lock and remove D_NEEDGIANT as the driver is now MPSAFE.
- Add 32-bit compatibility ioctl shims so you can use a 32-bit ipmitool
on FreeBSD/amd64.
- Add ipmi(4) to i386 and amd64 NOTES.

Add an OpenIPMI mostly compatible driver. This driver was developed
to work with ipmitools. It works with other tools that have an OpenIPMI
driver interface. The port will need to get updated to used this.
I have not implemented the IPMB mode yet so ioctl's for that don't
really do much otherwise it should work like the OpenIPMI version.
The ipmi.h definitions was derived from the ipmitool header file.
The bus attachments are done for smbios and pci/smbios. Differences
in bus probe order for modules/static are delt with. ACPI attachment
should be done.

This drivers registers with the watchdod(4) interface

Work to do:
- BT interface
- IPMB mode

This has been tested on Dell PE2850, PE2650 & PE850 with i386 & amd64
kernel.

I will link this into the build on next week.
