o POSIX.1e capabilities authorize overriding of VEXEC for VDIR based
on CAP_DAC_READ_SEARCH, but of !VDIR based on CAP_DAC_EXECUTE. Add
appropriate conditionals to vaccess() to take that into account.
o Synchronization cap_check_xxx() -> cap_check() change.

- Introduce cap_check_td() to reflect suser_td()
- Introduce non-portable cap_from_text2_np(), which converts a
text-form capability to an internal form relative to an existing
capability, and non-portable cap_to_text2_np(), which accepts
a flag argument specifying more about the text output format.
- Introduce CTT_* flags controlling the behavior of
cap_to_text2_np().

If zero bytes are allocated, return pointer to the middle of page-zero
(which is protected) so that the program will crash if it dereferences
this illgotten pointer.

When we truncate the msgbuf size because the last chunk is too small,
correctly terminate the phys_avail[] array - the VM system tests
the *end* for zero, not the start. This leads the VM startup to
attempt to recreate a duplicate set of pages for all physical memory.
XXX the msgbuf handling is suspiciously different on i386 vs
alpha/ia64...
o Add reference to TrustedBSD Project in license header.
o Update dated comments, including comment in extattr.h claiming that
no file systems support extended attributes.
o Improve comment consistency.
credential selection, rather than reference via a thread or process
pointer. This is part of a gradual migration to suser() accepting
a struct ucred instead of a struct proc, simplifying the reference
and locking semantics of suser().

refuses to start if it does not find a matching entry for the terminal
type.
My impression is that this is a problem in the shell, because
at least on PicoBSD images, the shell itself coredumps.
Anyways, this is the quickest fix i can come up with.
- Now that apm loadable module can inform its existence to other kernel
components (e.g. i386/isa/clock.c:startrtclock()'s TCS hack).
- Exchange priority of SI_SUB_CPU and SI_SUB_KLD for above purpose.
- Add simple arbitration mechanism for APM vs. ACPI. This prevents
the kernel enables both of them.
- Remove obsolete `#ifdef DEV_APM' related code.
- Add abstracted interface for Powermanagement operations. Public apm(4)
functions, such as apm_suspend(), should be replaced new interfaces.
Currently only power_pm_suspend (successor of apm_suspend) is implemented.
