All references to Host and Core have been removed, so this
class can now safely be lowered into Utility.

This in turn triggered some fallout where other files had
been transitively picking up includes that they needed from
FileSpec.h, so I've fixed those up as well.

Summary:
We've had two ways to print a "debug" log message.
- Log::GetDebug() was testing a Stream flag which was never set.
- Log::Debug() was checking for the presence of "log enable --debug"
flag.

Given that these two were used very rarely and we already have a
different way to specify "I want a more verbose log", I propose to remove
these two functions and migrate the callers to LLDB_LOGV. This commit
does that.

This moves the following classes from Core -> Utility.

ConstString
Error
RegularExpression
Stream
StreamString

The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes.  So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

This is a large API change that removes the two functions from
StreamString that return a std::string& and a const std::string&,
and instead provide one function which returns a StringRef.

Direct access to the underlying buffer violates the concept of
a "stream" which is intended to provide forward only access,
and makes porting to llvm::raw_ostream more difficult in the
future.

There were a number of issues with the Args class preventing
efficient use of strings and incoporating LLVM's StringRef class.
The two biggest were:

1. Backing memory stored in a std::string, so we would frequently
   have to use const_cast to get a mutable buffer for passing to
   various low level APIs.
2. backing std::strings stored in a std::list, which doesn't
   provide random access.

I wanted to solve these two issues so that we could provide
StringRef access to the underlying arguments, and also a way
to provide range-based access to the underlying argument array
while still providing convenient c-style access via an argv style
const char**.

The solution here is to store arguments in a single "entry" class
which contains the backing memory, a StringRef with precomputed
length, and the quote char.  The backing memory is a manually
allocated const char* so that it is not invalidated when the
container is resized, and there is a separate argv array provided
for c-style access.

*** 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.

r256927 included a duplicate StreamString header file. This patch simply removes the duplicate.
