Ed Maste 1e8f163709 Remove FIXME comments about tids on FreeBSD that no longer apply 
Spotted by John Wolfe.

Ed Maste 7fd845cc9d Threaded inferior support for FreeBSD 
Modelled in part on GDBRemoteCommunicationClient.

Ed Maste 502f9020a7 PT_CONTINUE and PT_STEP are process-scope on FreeBSD 
Although ptrace() can be passed a PID or TID for PT_CONTINUE and PT_STEP,
the kernel operates on all threads in the process in both cases.  (See
the FOREACH_THREAD_IN_PROC in FreeBSD's sys_process.c:kern_ptrace.)

Make this clear by using the PID from the ProcessMonitor instance.

Ed Maste 819e39901f FreeBSD: Replace GetSignalInfo with GetLwpInfo 
For thread support we are going to need other members of struct
ptrace_lwpinfo.

Matt Kopec edee182bef Fix FreeBSD build due to previous changes to ProcessMonitor::Detach.

Ashok Thirumurthi 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.

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

Daniel Malea 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

Johnny Chen 9ed5b49c45 Fix incomplete commit of http://llvm.org/viewvc/llvm-project?rev=147609&view=rev: 
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.
