c6672c8783 Rollback r177173. Some OSs may not have ptrace extensions which lldb expects when building. This needs to be accounted for.

a35970a6f6 Fix Linux bug that leaves lldb in invalid state after expression evaluation times out. 
- Handle EINVAL return code from ptrace(GETSIGINFO, ...): not an error, but 'group-stop' state on Linux
- propagate SIGSTOP to inferior in above case
- this commit resolves the failure in expression_command/timeout testcase

Thanks to Sean Callanan & Matt Kopec for helping debug this problem

743ecf4393 Patch from Matt Kopec: 
This patch fixes an issue where if lldb fails to attach to a process (ie. invalid pid) on Linux, the process monitor thread gets stuck waiting for a signal from the attach thread, which never comes due to not being signaled. It also implements StopOpThread which is used for both attach/launch cases as I'm not aware of any special handling needed for the attach case. Also, propagate 'Error' from the Detach function instead of using a bool.

30213ffc28 This patch combines common code from Linux and FreeBSD into 
a new POSIX platform.  It also contains fixes for 64bit FreeBSD.

The patch is based on changes by Mark Peek <mp@FreeBSD.org> and
"K. Macy" <kmacy@freebsd.org> in their github repo located at
https://github.com/fbsd/lldb.

13e8e1c37d This patch add a "fake" attach waiting for a real implementation and 
solve the build break due to the lack of this method.

It also propose a solution to the API changes in RegisterContext.

I upgraded also the the python version in the makefile. My linux
installation has python2.7 and AFAIK also the latest ubuntu
has this version of python so maybe is worth upgrading.

Patch by Marco Minutoli <mminutoli@gmail.com>

[Note: I had to hand merge in the diffs since patch thinks it is a corrupt patch.]

84ffe7033c linux: initial support for 'real' signal handling 
This patch upgrades the Linux process plugin to handle a larger range of signal
events.  For example, we can detect when the inferior has "crashed" and why,
interrupt a running process, deliver an arbitrary signal, and so on.

570243b5d9 Delay sync with the parent thread in ProcessLinux/ProcessMonitor. 
This patch removes a potential race condition between a process monitor thread
and its parent waiting to interrogate the success/failure of the launch.

e6f9f66b39 Add a new Process plugin for Linux. 
This component is still at an early stage, but allows for simple
breakpoint/step-over operations and basic process control.

The makefiles are set up to build the plugin under Linux only.
