to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
A fairly simple operation as setting a breakpoint (writing a breakpoint
opcode) at a given address was going through three classes:
NativeProcessProtocol which called NativeBreakpointList, which then
called SoftwareBrekpoint, only to end up again in NativeProcessProtocol
to do the actual writing itself. This is unnecessarily complex and can
be simplified by moving all of the logic into NativeProcessProtocol
class itself, removing a lot of boilerplate.
One of the reeasons for this complexity was that (it seems)
NativeBreakpointList class was meant to hold both software and hardware
breakpoints. However, that never materialized, and hardware breakpoints
are stored in a separate map holding only hardware breakpoints.
Essentially, this patch makes software breakpoints follow that approach
by replacing the heavy SoftwareBraekpoint with a light struct of the
same name, which holds only the data necessary to describe one
breakpoint. The rest of the logic is in the main class. As, at the
lldb-server level, handling software and hardware breakpoints is very
different, this seems like a reasonable state of things.

These functions were unused as everyone just went straight for the
direct operations on the register context. In fact, the
Save/RestoreAllRegisters actually appear to be wrong (inverted). Thanks
to Tatyana for pointing this out.
These functions are not very useful now that we can guarantee that each
thread always contains a valid register context, so I just delete them.

Summary:
This commit removes the concrete_frame_idx member from
NativeRegisterContext and related functions, which was always set to
zero and never used.
I also change the native thread class to store a NativeRegisterContext
as a unique_ptr (documenting the ownership) and make sure it is always
initialized (most of the code was already blindly dereferencing the
register context pointer, assuming it would always be present -- this
makes its treatment consistent).

Summary:
The usage of shared_from_this forces us to separate construction and
initialization phases, because shared_from_this() is not available in
the constructor (or destructor). The shared semantics are not necessary,
as we always have a clear owner of the native process class
(GDBRemoteCommunicationServerLLDB object). Even if we need shared
semantics in the future (which I think we should strongly avoid),
reverting this will not be necessary -- the owners can still easily
store the native process object in a shared pointer if they really want
to -- this just prevents the knowledge of that from leaking into the
class implementation.
After this a NativeThread object will hold a reference to the parent
process (instead of a weak_ptr) -- having a process instance always
available allows us to simplify some logic in this class (some of it was
already simplified because we were asserting that the process is
available, but this makes it obvious).

This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.
A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error". Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around. Hopefully nothing too
serious.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

This change brings in lldb-gdbserver (llgs) specifically for Linux x86_64.
(More architectures coming soon).
Not every debugserver option is covered yet. Currently
the lldb-gdbserver command line can start unattached,
start attached to a pid (process-name attach not supported yet),
or accept lldb attaching and launching a process or connecting
by process id.
The history of this large change can be found here:
https://github.com/tfiala/lldb/tree/dev-tfiala-native-protocol-linux-x86_64
Until mid/late April, I was not sharing the work and continued
to rebase it off of head (developed via id tfiala@google.com). I switched over to
user todd.fiala@gmail.com in the middle, and once I went to github, I did
merges rather than rebasing so I could share with others.
