BroadcastEvent currently takes its EventData* param and shoves it into
an Event object, which takes ownership of the pointer and places it into
a shared_ptr to manage the lifetime.
Instead of relying on `new` and passing raw pointers around, I think it
would make more sense to create the shared_ptr up front.

A common debugging pattern is to set a breakpoint that only stops after
a number of hits is recorded. The current implementation never resets
the hit count of breakpoints; as such, if a user re-`run`s their
program, the debugger will never stop on such a breakpoint again.
This behavior is arguably undesirable, as it renders such breakpoints
ineffective on all but the first run. This commit changes the
implementation of the `Will{Launch, Attach}` methods so that they reset
the _target's_ breakpoint hitcounts.

Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).
This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

Summary:
Using a BreakpointList corrupts the breakpoints' IDs because
BreakpointList::Add sets the ID, so use a vector instead, and
update the signature to return the vector wrapped in an
llvm::Expected which can propagate any error from the inner
call to StringIsBreakpointName.
Note that, despite the similar name, SBTarget::FindBreakpointsByName
doesn't suffer the same problem, because it uses a SBBreakpointList,
which is more like a BreakpointIDList than a BreakpointList under the
covers.
Add a check to TestBreakpointNames that, without this fix, notices the
ID getting mutated and fails.

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.

I was looking at the code in BreakpointList.cpp and found it deserved a
quick cleanup.
- Use std::vector instead of a std::list.
- Extract duplicate code for notifying.
- Remove code duplication when returning a const value.
- Use range-based for loop.
- Use early return in loops.

This patch removes the comments grouping header includes. They were
added after running IWYU over the LLDB codebase. However they add little
value, are often outdates and burdensome to maintain.

When introduced, breakpoint names were just tags that you could
apply to breakpoints that would allow you to refer to a breakpoint
when you couldn't capture the ID, or to refer to a collection of
breakpoints.
This change makes the names independent holders of breakpoint options
that you can then apply to breakpoints when you add the name to the
breakpoint. It adds the "breakpoint name configure" command to set
up or reconfigure breakpoint names. There is also full support for
then in the SB API, including a new SBBreakpointName class.
The connection between the name and the breakpoints
sharing the name remains live, so if you reconfigure the name, all the
breakpoint options all change as well. This allows a quick way
to share complex breakpoint behavior among a bunch of breakpoints, and
a convenient way to iterate on the set.
You can also create a name from a breakpoint, allowing a quick way
to copy options from one breakpoint to another.
I also added the ability to make hidden and delete/disable protected
names. When applied to a breakpoint, you will only be able to list,
delete or disable that breakpoint if you refer to it explicitly by ID.
This feature will allow GUI's that need to use breakpoints for their
own purposes to keep their breakpoints from getting accidentally
disabled or deleted.

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.

Also if you set a breakpoint with an invalid name, we'll
refuse to set the breakpoint rather than silently ignoring
the name.

*** 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.

There were 6 on darwin. All of these were related to the recent changes for exec.
llvm-svn: 194298

Fixed the test case for "test/functionalities/exec/TestExec.py" on Darwin.
The issue was breakpoints were persisting and causing problems. When we exec, we need to clear out the process and target and start fresh with nothing and let the breakpoints populate themselves again. This patch correctly clears out the breakpoints and also flushes the process so that the objects (process/thread/frame) give out valid information.

Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary.
So I defined a new "lldb::offset_t" which should be used for all file offsets.
After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed.
Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections.

No one was using it and Locker(pthread_mutex_t *) immediately asserts for
pthread_mutex_t's that don't come from a Mutex anyway. Rather than try to make
that work, we should maintain the Mutex abstraction and not pass around the
platform implementation...
Make Mutex::Locker::Lock take a Mutex & or a Mutex *, and remove the constructor
taking a pthread_mutex_t *. You no longer need to call Mutex::GetMutex to pass
your mutex to a Locker (you can't in fact, since I made it private.)

Cleaned up the Mutex::Locker and the ReadWriteLock classes a bit.
Also cleaned up the GDBRemoteCommunication class to not have so many packet functions. Used the "NoLock" versions of send/receive packet functions when possible for a bit of performance.
