acbb1a5db5 Fixed "log enable linux registers" and added a test.
- Eliminated the use of static for methods that read m_register_infos, so that these routines can be implemented in the base class.
- Eliminated m_register_infos in the base class because this is not used when derived classes call UpdateRegisterInfo.
- Also moved the namespace using declarations from headers to source files.

Thanks to Daniel and Samuel for their review feedback.

6e0ff1a3cb Changed the formerly pure virtual function:
namespace lldb_private {
    class Thread
    {
        virtual lldb::StopInfoSP
        GetPrivateStopReason() = 0;
    };
}

To not be virtual. The lldb_private::Thread now handles the correct caching and will call a new pure virtual function:

namespace lldb_private {
    class Thread
    {
        virtual bool
        CalculateStopInfo() = 0;
    }
}

This function must be overridden by thead lldb_private::Thread subclass and the only thing it needs to do is to set the Thread::StopInfo() with the current stop reason and return true, or return false if there is no stop reason. The  lldb_private::Thread class will take care of calling this function only when it is required. This allows lldb_private::Thread subclasses to be a bit simpler and not all need to duplicate the cache and invalidation settings.

Also renamed:

lldb::StopInfoSP
lldb_private::Thread::GetPrivateStopReason();

To:

lldb::StopInfoSP
lldb_private::Thread::GetPrivateStopInfo();

Also cleaned up a case where the ThreadPlanStepOverBreakpoint might not re-set its breakpoint if the thread disappears (which was happening due to a bug when using the OperatingSystem plug-ins with memory threads and real threads).

d36712df8d Refactoring for struct UserArea:
- Decouples RegisterContext_x86_64 from UserArea.
- Restores the original definition of UserArea so that it can be used to generate offsets for use with ptrace.
- Moves UserArea to the 64-bit Linux specialization.

- Also fixes an off-by-one error for the size of m_gpr.
- Also adds a TODO comment noting the need for a mechanism to identify the correct plugin based on the target OS (and architecture).

160c9d81e0 <rdar://problem/13700260>
<rdar://problem/13723772>

Modified the lldb_private::Thread to work much better with the OperatingSystem plug-ins. Operating system plug-ins can now return have a "core" key/value pair in each thread dictionary for the OperatingSystemPython plug-ins which allows the core threads to be contained with memory threads. It also allows these memory threads to be stepped, resumed, and controlled just as if they were the actual backing threads themselves.

A few things are introduced:
- lldb_private::Thread now has a GetProtocolID() method which returns the thread protocol ID for a given thread. The protocol ID (Thread::GetProtocolID()) is usually the same as the thread id (Thread::GetID()), but it can differ when a memory thread has its own id, but is backed by an actual API thread.
- Cleaned up the Thread::WillResume() code to do the mandatory parts in Thread::ShouldResume(), and let the thread subclasses override the Thread::WillResume() which is now just a notification.
- Cleaned up ClearStackFrames() implementations so that fewer thread subclasses needed to override them
- Changed the POSIXThread class a bit since it overrode Thread::WillResume(). It is doing the wrong thing by calling "Thread::SetResumeState()" on its own, this shouldn't be done by thread subclasses, but the current code might rely on it so I left it in with a TODO comment with an explanation.

0118635979 Fix the Linux build issues introduced by r178191.
- All Linux logging channels now use a single global instance of lldb_private::Log, to handle the case of logging during process tear down.
- Also removed a single use of LogSP in FreeBSD and fixed a typo in a comment while reading through ProcessKDPLog.
