The UserSettings controllers must be initialized & terminated in the
correct order.  Previously this was tacitly implemented but not
enforced, so it was possible to accidentally do things in the wrong
order and cause problems.  This fixes that problem.

This patch supports building the Linux platform plugin, and should also support
the MacOSX plugin as well (the MacOSX side has not been tested, unfortunately).
A small typo was corrected in lldb.cpp to initialize the new platform code on
Linux.

member variable (m_packet_timeout which is a value in seconds). This value is
then used for all packets sent to/from the remote GDB server.

an interface to a local or remote debugging platform. By default each host OS
that supports LLDB should be registering a "default" platform that will be
used unless a new platform is selected. Platforms are responsible for things
such as:
- getting process information by name or by processs ID
- finding platform files. This is useful for remote debugging where there is 
  an SDK with files that might already or need to be cached for debug access.
- getting a list of platform supported architectures in the exact order they
  should be selected. This helps the native x86 platform on MacOSX select the
  correct x86_64/i386 slice from universal binaries.
- Connect to remote platforms for remote debugging
- Resolving an executable including finding an executable inside platform
  specific bundles (macosx uses .app bundles that contain files) and also
  selecting the appropriate slice of universal files for a given platform.

So by default there is always a local platform, but remote platforms can be
connected to. I will soon be adding a new "platform" command that will support
the following commands:
(lldb) platform connect --name machine1 macosx connect://host:port
Connected to "machine1" platform.
(lldb) platform disconnect macosx

This allows LLDB to be well setup to do remote debugging and also once 
connected process listing and finding for things like:
(lldb) process attach --name x<TAB>

The currently selected platform plug-in can now auto complete any available
processes that start with "x". The responsibilities for the platform plug-in
will soon grow and expand.

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.

I didn't notice there was already an ObjectFile::GetEntryPoint.  Move that over to GetEntryPointAddress 'cause that's more consistent with other functions in ObjectFile, do the mutatis mutandi and also in the ELF case I return a section offset address rather than a bare load address.

Reverting the part of the debug-in-ofile patch from earlier today that removes them from the shared module list.  That was causing a bunch of asserts.  Greg is working on a better fix.

llvm-svn: 127201

Add a method "GetEntryPoint" to the ObjectFile class, and implement it on MachO & ELF - though the ELF implementation is probably a little weak.  Then use this method in place of directly looking for "start" in the ThreadPlanCallFunction constructor to find the stopping point for our function evaluation.

Add thread state initialization to the thread where the interactive
interpreter is run (which is separate from the thread where
Py_Initialize is called, where this normally gets set up).

we debug, compile + fix, and debug again.

It will just load all files exactly where the files state they are (file
addresses == load addresses). This is used when the llvm::Triple::OSType is
set to llvm::Triple::UnknownOS or llvm::Triple::NoOS.
