Detailed Description

Encapsulate string representation of stack trace.

Some platform-specific areas of this code have been adapted from examples found elsewhere. Specifically,

• the GLIBC stack generation uses the documented "backtrace" API and is adapted from examples shown in relevant documentation and repeated elsewhere, e.g., http://www.linuxselfhelp.com/gnu/glibc/html_chapter/libc_33.html
• VxWorks kernel-mode stack tracing is adapted from a code example in the VxWorks FAQ at http://www.xs4all.nl/~borkhuis/vxworks/vxw_pt5.html although the undocumented functions it uses are also mentioned in various documents available on the WindRiver support website.

If you add support for a new platform, please add a bullet to the above list with durable references to the origins of your code.
