1. Using mach port number, just like when inferior is paused.
2. Use key:value pair of thread used time instead of comma separated notation.

Enrico Granata b576bba229 <rdar://problem/12028723>
Adding useful formatting options to the expression (expr) command.
As a side effect of this change, the -d option now supports the same three-values enumeration that frame variables uses (run, don't run, none) instead of a boolean like it did previously

These options do not apply to print, p or po because these are aliased to not take any options.
In order to use them, use expression or expr.

Greg Clayton f9fc609fe7 Expanded the flags that can be set for a command object in lldb_private::CommandObject. This list of available flags are:
enum
{
    //----------------------------------------------------------------------
    // eFlagRequiresTarget
    //
    // Ensures a valid target is contained in m_exe_ctx prior to executing
    // the command. If a target doesn't exist or is invalid, the command
    // will fail and CommandObject::GetInvalidTargetDescription() will be
    // returned as the error. CommandObject subclasses can override the
    // virtual function for GetInvalidTargetDescription() to provide custom
    // strings when needed.
    //----------------------------------------------------------------------
    eFlagRequiresTarget         = (1u << 0),
    //----------------------------------------------------------------------
    // eFlagRequiresProcess
    //
    // Ensures a valid process is contained in m_exe_ctx prior to executing
    // the command. If a process doesn't exist or is invalid, the command
    // will fail and CommandObject::GetInvalidProcessDescription() will be
    // returned as the error. CommandObject subclasses can override the
    // virtual function for GetInvalidProcessDescription() to provide custom
    // strings when needed.
    //----------------------------------------------------------------------
    eFlagRequiresProcess        = (1u << 1),
    //----------------------------------------------------------------------
    // eFlagRequiresThread
    //
    // Ensures a valid thread is contained in m_exe_ctx prior to executing
    // the command. If a thread doesn't exist or is invalid, the command
    // will fail and CommandObject::GetInvalidThreadDescription() will be
    // returned as the error. CommandObject subclasses can override the
    // virtual function for GetInvalidThreadDescription() to provide custom
    // strings when needed.
    //----------------------------------------------------------------------
    eFlagRequiresThread         = (1u << 2),
    //----------------------------------------------------------------------
    // eFlagRequiresFrame
    //
    // Ensures a valid frame is contained in m_exe_ctx prior to executing
    // the command. If a frame doesn't exist or is invalid, the command
    // will fail and CommandObject::GetInvalidFrameDescription() will be
    // returned as the error. CommandObject subclasses can override the
    // virtual function for GetInvalidFrameDescription() to provide custom
    // strings when needed.
    //----------------------------------------------------------------------
    eFlagRequiresFrame          = (1u << 3),
    //----------------------------------------------------------------------
    // eFlagRequiresRegContext
    //
    // Ensures a valid register context (from the selected frame if there
    // is a frame in m_exe_ctx, or from the selected thread from m_exe_ctx)
    // is availble from m_exe_ctx prior to executing the command. If a
    // target doesn't exist or is invalid, the command will fail and
    // CommandObject::GetInvalidRegContextDescription() will be returned as
    // the error. CommandObject subclasses can override the virtual function
    // for GetInvalidRegContextDescription() to provide custom strings when
    // needed.
    //----------------------------------------------------------------------
    eFlagRequiresRegContext     = (1u << 4),
    //----------------------------------------------------------------------
    // eFlagTryTargetAPILock
    //
    // Attempts to acquire the target lock if a target is selected in the
    // command interpreter. If the command object fails to acquire the API
    // lock, the command will fail with an appropriate error message.
    //----------------------------------------------------------------------
    eFlagTryTargetAPILock       = (1u << 5),
    //----------------------------------------------------------------------
    // eFlagProcessMustBeLaunched
    //
    // Verifies that there is a launched process in m_exe_ctx, if there
    // isn't, the command will fail with an appropriate error message.
    //----------------------------------------------------------------------
    eFlagProcessMustBeLaunched  = (1u << 6),
    //----------------------------------------------------------------------
    // eFlagProcessMustBePaused
    //
    // Verifies that there is a paused process in m_exe_ctx, if there
    // isn't, the command will fail with an appropriate error message.
    //----------------------------------------------------------------------
    eFlagProcessMustBePaused    = (1u << 7)
};

Now each command object contains a "ExecutionContext m_exe_ctx;" member variable that gets initialized prior to running the command. The validity of the target objects in m_exe_ctx are checked to ensure that any target/process/thread/frame/reg context that are required are valid prior to executing the command. Each command object also contains a Mutex::Locker m_api_locker which gets used if eFlagTryTargetAPILock is set. This centralizes a lot of checking code that was previously and inconsistently implemented across many commands.

Python OS plug-ins now fetch thread registers lazily.

Also changed SBCommandInterpreter::HandleCommand() to not take the API lock. The logic here is that from the command line you can execute a command that might result in another thread (like the private process thread) to execute python or run any code that can re-enter the public API. When this happens, a deadlock immediately occurs for things like "process launch" and "process attach".

Setting breakpoints using "breakpoint set --selector <SEL>" previously didn't when there was no dSYM file.

Also fixed issues in the test suite that arose after fixing the bug.

Also fixed the log channels to properly ref count the log streams using weak pointers to the streams. This fixes a test suite problem that would happen when you specified a full path to the compiler with the "--compiler" option.

Add unconditional logging messages to every place in debugserver
where we send a SIGKILL signal or do a ptrace PT_KILL call to
terminate the inferior process.  When the debuggee is silently
killed off, the console logging from debugserver can disambiguate
whether debugserver killed off the process because it failed to
completely set it up, becuase it was told to (via the "k" packet),
or if some external daemon killed it.

Andrew Kaylor d362d910f3 Setting TestInferiorChanged.py to expectedFailureLinux because of bugzilla 14662.
Note that the test actually fails before reaching the assertion described in that bug, but the failure is a trivial matter of adding OS-conditional expected stop reason strings (as noted by new comments in this patch).

Implement the ability for Python commands to be interrupted by pressing CTRL+C
Also add a new Mutex subclass that attempts to be helpful for debugging by logging actions performed on it

FYI of all interested - there is a separate deadlocking issue related to how LLDB dispatches CTRL+C that might cause LLDB to deadlock upon pressing CTRL+C while in a Python command.
This is not a regression, and was just previously masked by us not even trying to bail out of Python commands, so that it would not be clear from a user perspective whether we were
deadlocked or stuck in an inconsistent state within the Python interpreter.

Sean Callanan 7be70e8528 This patch removes the SymbolFileSymtab support
for reporting class types from Objective-C runtime
class symbols.  Instead, LLDB now queries the 
Objective-C runtime for class types.

We have also added a (minimal) Objective-C runtime
type vendor for Objective-C runtime version 1, to 
prevent regressions when calling class methods in
the V1 runtime.

Other components of this fix include:

- We search the Objective-C runtime in a few more
  places.

- We enable enumeration of all members of
  Objective-C classes, which Clang does in certain
  circumstances.

- SBTarget::FindFirstType and SBTarget::FindTypes
  now query the Objective-C runtime as needed.

- I fixed several test cases.
