Break out stack(9) from ddb(4):
- Introduce per-architecture stack_machdep.c to hold stack_save(9). - Introduce per-architecture machine/stack.h to capture any common definitions required between db_trace.c and stack_machdep.c. - Add new kernel option "options STACK"; we will build in stack(9) if it is defined, or also if "options DDB" is defined to provide compatibility with existing users of stack(9).
Add new stack_save_td(9) function, which allows the capture of a stacktrace of another thread rather than the current thread, which the existing stack_save(9) was limited to. It requires that the thread be neither swapped out nor running, which is the responsibility of the consumer to enforce.
Update stack(9) man page.
Build tested: amd64, arm, i386, ia64, powerpc, sparc64, sun4v Runtime tested: amd64 (rwatson), arm (cognet), i386 (rwatson)

Modify stack(9) stack_print() and stack_sbuf_print() routines to use new linker interfaces for looking up function names and offsets from instruction pointers. Create two variants of each call: one that is "DDB-safe" and avoids locking in the linker, and one that is safe for use in live kernels, by virtue of observing locking, and in particular safe when kernel modules are being loaded and unloaded simultaneous to their use. This will allow them to be used outside of debugging contexts.
Modify two of three current stack(9) consumers to use the DDB-safe interfaces, as they run in low-level debugging contexts, such as inside lockmgr(9) and the kernel memory allocator.
Update man page.
