If a command argument contains a space then it have to be escaped with
backslash signs so the argument parsing logic can parse it properly.
This CL fixes the tab completion code for the arguments to create
complitions with correctly escaped strings.

These are useful helpers over the low-level API of the FormattersContainer, and since we're actually going to start moving formatters into plugins, it makes sense to simplify things

Summary:
When calling find_first_of and find_last_of on a single character,
we can instead just call find / rfind and make our intent more
clear.

Summary:
This was removed from the other ABI plugins long ago. This removes
a warning that was happening in this unused code as a result of
adding 2 new types to Scalar.h (e_uint128 and e_sint128).

Historically, data formatters all exist in a global repository (the category map)
On top of that, some formatters can be "hardcoded" when the conditions under which they apply are not expressible as a typename (or typename regex)
This change paves the way to move formatters into per-language buckets such that the C++ plugin is responsible for ownership of the C++ formatters, and so on
The advantages of this are:
a) language formatters only get created when they might apply
b) formatters for a language are clearly owned by the matching language plugin
The current model is one of static instantiation, that is a language knows the full set of formatters it vends and that is only asked-for once, and then handed off to the FormatManager
In a future revision it might be interesting to add similar ability to the language runtimes, and monitor for certain shared library events to add even more library-specific formatters
No formatters are moved as part of this change, so practically speaking this is NFC

When detaching, we need to detach from all threads of the inferior and not just the main one.
Without this, a multi-threaded inferior would usually crash once the server exits.
llvm-svn: 246549
Linux sometimes sends us a PTRACE_EVENT_EXIT when an inferior process gets a SIGKILL. This can be
confusing, since normally we don't expect any events when the inferior is stopped. This commit
adds code to handle this situation (resume the thread and let it exit normally) and avoid an
assertion failure in ResumeThread().

We have one subclass named DWARFASTParserClang that implements all of the clang specific AST type parsing. This keeps all DWARF parsing in the DWARF plug-in. Moved all of the DWARF parsing code that was in ClangASTContext over into DWARFASTParserClang.
lldb_private::TypeSystem classes no longer have any DWARF parsing functions in them, but they can hand out a DWARFASTParser:
virtual DWARFASTParser *
GetDWARFParser ()
{
return nullptr;
}
This keeps things clean and makes for easy merging when we have different AST's for different languages.

The Language plugin is menat to answer language-specific questions that are not bound to the existence of a process. Those are still the domain of the LanguageRuntime plugin
The Language plugin will, instead, answer questions such as providing language-specific data formatters or expression evaluation
At the moment, the interface is hollowed out, and empty do-nothing plugins have been setup for ObjC, C++ and ObjC++

This will do things like,
given mylibrary,
return
libmylibrary.dylib on OSX
mylibrary.dll on Windows
and so on for other platforms
It is currently implemented for Windows, Darwin, and Linux. Other platforms should fill in accordingly

Added a new class called DWARFDIE that contains a DWARFCompileUnit and DWARFDebugInfoEntry so that these items always stay together.
There were many places where we just handed out DWARFDebugInfoEntry pointers and then use them with a compile unit that may or may not be the correct one. Clients outside of DWARFCompileUnit and DWARFDebugInfoEntry should all be dealing with DWARFDIE instances instead of playing with DWARFCompileUnit/DWARFDebugInfoEntry pairs manually.
This paves to the way for some modifications that are coming for DWO.

SUMMARY:
This patch implements Target::GetBreakableLoadAddress() method that takes an address
and checks for any reason there is a better address than this to put a breakpoint on.
If there is then return that address.
MIPS uses this method to avoid breakpoint in delay slot.

code that looks for a second stop-reply packet in response to an
interrupt (control-c). This is to handle the case where where a
stop packet is making its way up to lldb right as lldb decides to
interrupt the inferior. If the inferior is running and we interrupt
it, we'd expect a T11 type response meaning that the inferior halted
because of the interrupt. But if the interrupt gets a T05 type
response instead, meaning that we stopped execution by hitting a
breakpoint or whatever, then the interrupt was received while the
inferior was already paused and so it is treated as a "?" packet
-- the remote stub will send the stop message a second time.
There's a timeout where we wait to get this second stop reply packet
in SendContinuePacketAndWaitForResponse, currently 1ms. For a slow
remote target, it may take longer than that to send the second stop
reply packet. If that happens, then lldb will use that second stop
reply packet as the response for the next packet request it makes
to the remote stub. The two will be out of sync by one packet for
the rest of the debug session and it's going to go badly from then on.
I've seen times as slow as 46ms, and given the severity of missing that
second stop reply packet, I'm increasing the timeout to 100ms, or 0.1sec.

This updated patches correct problems in arm hardware watchpoint support patch posted earlier.
This patch has been tested on samsung chromebook (ARM - Linux) and PandaBoard using basic watchpoint test application.
Also it was tested on Nexus 7 Android device.
On chromebook linux we are able to set and clear all types of watchpoints but on android we end up getting a watchpoint packet error because we are not able to call hardware watchpoint ptrace functions successfully.
