[sanitizer_common] Refactor SuspendedThreadsList to let it be used with different thread ID types

Authored by glider on Jul 23 2014, 9:00 AM.



This patch makes SuspendedThreadsList a template parameterized by the thread ID type, so that different platforms (e.g. Linux and OSX) can share the implementation. The SuspendedThreadsRegisters interface is extracted to keep existing code that uses SuspendedThreadsList platform-agnostic.

Holds the list of suspended threads and provides an interface to dump their
register contexts.

Closing this issue per the offline discussion. I like your suggestion more.
