Similar to mfiutil, drop local definition of powerof2() and use version
from <sys/param.h> instead.

- Save errno values before calling warn(3) so that errors are correctly
reported.
- Check for malloc() failures.

mdoc: move remaining sections into consistent order

This pertains mostly to FILES, HISTORY, EXIT STATUS and AUTHORS sections.

Fixed static linkage.

Fix mptutil's method for locating disk devices attached to a specific
mpt(4) controller. Previously, the code assumed that multiple match
patterns provided to an XPT_DEV_MATCH request were ANDed together.
Instead, they are ORed. Instead, to match peripherals for a specific bus,
one query needs to be performed to lookup the path ID of the bus. A second
query can then be performed matching peripherals attached to that path.
This approach also makes the code a bit cleaner as the returned match
results do not mix bus and perphierals.

- Don't emit a warning in 'show adapter' if the IOC2 or IOC6 pages are not
present. mpt(4) controllers that do not support RAID do not have an IOC6
page, for example.
- Correct a check for a missing page error in a debug function.
