- ProcessMonitor::[Do|Serve]Operation no longer depend on file descriptors!
- removed unused member functions CloseFD and EnableIPC
- add semaphores to signal when an Operation is ready to be processed/complete.
This commit fixes a bug that was identified under stress-testing (i.e. build
LLVM while running tests) that led to LLDB becoming unresponsive because the
read/write operations on file descriptors in ProcessMonitor were not checked.
Other test runner improvement/convenience:
- pickup environment variables LLDB_LINUX_LOG and LLDB_LINUX_LOG_OPTIONS to
enable (Linux) logging when running the test suite. Example usage:
$ LLDB_LINUX_LOG="mylog.txt" LLDB_LINUX_LOG_OPTIONS="process thread" python dotest.py

- 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.

- 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

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.

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.

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.

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.

This patch removes a potential race condition between a process monitor thread
and its parent waiting to interrogate the success/failure of the launch.

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.
