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.

Host.cpp was missing Error.h and the implementation of
LaunchProcess. Once againg I have added a "fake" implementation
waiting for a real one.
Fixed the call GetAddressRange to reflect the new interface in
DynamicLoaderLinuxDYLD.cpp.
Added string.h to ARM_DWARF_Registers.cpp that is needed for ::memset.

Specifying the new arguments as NULL is appropriate for now as this is
backwards-compatible with the old invocation.

Using the new synthetic symbols generated by ObjectFileELF, have the Linux
dynamic loader plugin generate a thread plan that will take us thru a PLT entry
to the corresponding target function.

ELF object files do not implicitly have a symbol named "start" as an entry
point. For example, on Linux it is often named "_start", but can be trivially
set to any symbol by passing an --entry argument to the linker.
Use the ELF header to determine the entry point and resolve the associated
section based on that address.
Also, update the linux dynamic loader to call GetEntryPointAddress instead of
GetEntryPoint.

it should live and the lldb_private::Process takes care of managing the
auto pointer to the dynamic loader instance.
Also, now that the ArchSpec contains the target triple, we are able to
correctly set the Target architecture in DidLaunch/DidAttach in the subclasses,
and then the lldb_private::Process will find the dynamic loader plug-in
by letting the dynamic loader plug-ins inspect the arch/triple in the target.
So now the ProcessGDBRemote plug-in is another step closer to be purely
process/platform agnostic.
I updated the ProcessMacOSX and the ProcessLinux plug-ins accordingly.

This fixes a bug where the dynamic loader rendezvous was not updating its
internal state when first initialized.

This patch is enough to have shared objects recognized by LLDB. We can handle
position independent executables. We can handle dynamically loaded modules
brought in via dlopen.
The DYLDRendezvous class provides an interface to a structure present in the
address space of ELF-based processes. This structure provides the address of a
function which is called by the linker each time a shared object is loaded and
unloaded (thus a breakpoint at that address will let LLDB intercept such
events), a list of entries describing the currently loaded shared objects, plus
a few other things.
On Linux, processes are brought up with an auxiliary vector on the stack. One
element in this vector contains the (possibly dynamic) entry address of the
process. One does not need to walk the stack to find this information as it is
also available under /proc/<pid>/auxv. The new AuxVector class provides a
convenient read-only view of this auxiliary vector information. We use the
dynamic entry address and the address as specified in the object file to compute
the actual load address of the inferior image. This strategy works for both
normal executables and PIE's.
