Now -shlib flag can be provided alongside with names of symbols files:
(lldb) target symbols add --shlib stripper-lib.so unstripper-lib.so
This is helpful when default matching mechanisms by name and UUID
can't find a module, and the user needs to explicitly specify
which module the given symbol file belongs to.

The interpreter gets invoked in the sigint handler to cancel
long-running Python operations. That requires the interpreter
lock, but that may be held by the Python operation that's getting
interrupted, so the mutex needs to be recursive.

Summary:
The classes have no dependencies, and they are used both by lldb and
lldb-server, so it makes sense for them to live in the lowest layers.

The Timer destructor would grab a global mutex in order to update
execution time. Add a class to define a category once, statically; the
class adds itself to an atomic singly linked list, and thus subsequent
updates only need to use an atomic rather than grab a lock and perform a
hashtable lookup.

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.

Summary:
UniqueCStringMap "sorts" the entries for fast lookup, but really it only cares about uniqueness. ConstString can be compared by pointer alone, rather than with strcmp, resulting in much faster comparisons. Change the interface to take ConstString instead, and propagate use of the type to the callers where appropriate.

This updates the regular expression used to match host/port pairs for the gdb-remote command to also match IPv6 addresses.
The IPv6 address matcher is very generic and does not really check for structural validity of the address. It turns out that IPv6 addresses are very complicated.

The attribute was fairly dubious as: a) we shouldn't tell the compiler
when to inline functions, b) GCC complains that the function may be
not always inlinable.

This functionality is subsumed by DataBufferLLVM, which is
also more efficient since it will try to mmap. However, we
don't yet support mmaping writable private sections, and in
some cases we were using ReadFileContents and then modifying
the buffer. To address that I've added a flag to the
DataBufferLLVM methods that allow you to map privately, which
disables the mmaping path entirely. Eventually we should teach
DataBufferLLVM to use mmap with writable private, but that is
orthogonal to this effort.

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

With this patch, the only dependency left is from Utility
to Host. After this is broken, Utility will finally be
standalone.

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.

Summary:
This patch adds accurate dependency specifications to the mail LLDB libraries and tools.
In all cases except lldb-server, these dependencies are added in addition to existing dependencies (making this low risk), and I performed some code cleanup along the way.
For lldb-server I've cleaned up the LLVM dependencies down to just the minimum actually required. This is more than lldb-server actually directly references, and I've left a todo in the code to clean that up.

This patch fixes use of incorrect `%zi` to format a plain `int`, and using
`%llu` to format a `uint64_t`. The fix is to use the new typesafe

LLDB needs some minor changes to adopt PrettyStackTrace after https://reviews.llvm.org/D27683.
We remove our own SetCrashDescription() function and use LLVM-provided RAII objects instead.
We also make sure LLDB doesn't define __crashtracer_info__ which would collide with LLVM's definition.

I found the race condition in:
ScriptInterpreter *CommandInterpreter::GetScriptInterpreter(bool can_create);
More than one "ScriptInterpreter *" was being returned due to the race which caused any clients with the first one to now be pointing to freed memory and we would quickly crash.
Added a test to catch this so we don't regress.

The long-term goal here is to get rid of the functions
GetArgumentAtIndex() and GetQuoteCharAtIndex(), instead
replacing them with operator based access and range-based for
enumeration. There are a lot of callsites, though, so the
changes will be done incrementally, starting with this one.

This was a bit tricky, especially for things like
OptionValueArray and OptionValueDictionary since they do some
funky string parsing. Rather than try to re-write line-by-line
I tried to make the StringRef usage idiomatic, even though
it meant often re-writing from scratch large blocks of code
in a different way while keeping true to the original intent.
The finished code is a big improvement though, and often much
shorter than the original code. All tests and unit tests
pass on Windows and Linux.

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.
