This removes the HashString function from StringExtraces and replaces
its uses with calls to djbHash from DJB.h
This is *almost* NFC. While the algorithm is identical, the djbHash
implementation in StringExtras used 0 as its seed while the
implementation in DJB uses 5381. The latter has been shown to result in
less collisions and improved avalanching.

Summary:
The ObjectFile class was used to determine the architecture of a running
process by inspecting it's main executable. There were two issues with
this:
- it's in the wrong layer
- the call can be very expensive (it can end up computing the crc of the
whole file).
Since the process is running on the host, ideally we would be able to
just query the data straight from the OS like darwin does, but there
doesn't seem to be a reasonable way to do that. So, this fixes the
layering issue by using the llvm object library to inspect the file.
Since we know the process is already running on the host, we just need
to peek at a few bytes of the elf header to determine whether it's 32-
or 64-bit (which should make this faster as well).
Pretty much the same logic was implemented in
NativeProcessProtocol::ResolveProcessArchitecture, so I delete this
logic and replace calls with GetProcessInfo.

Patch by Alexandre Yukio Yamashita <alexandre.yamashita@eldorado.org.br>
llvm-svn: 323100
Summary:
There was some confusion in the code about how to represent process
environment. Most of the code (ab)used the Args class for this purpose,
but some of it used a more basic StringList class instead. In either
case, the fact that the underlying abstraction did not provide primitive
operations for the typical environment operations meant that even a
simple operation like checking for an environment variable value was
several lines of code.
This patch adds a separate Environment class, which is essentialy a
llvm::StringMap<std::string> in disguise. To standard StringMap
functionality, it adds a couple of new functions, which are specific to
the environment use case:
- (most important) envp conversion for passing into execve() and likes.
Instead of trying to maintain a constantly up-to-date envp view, it
provides a function which creates a envp view on demand, with the
expectation that this will be called as the very last thing before
handing the value to the system function.
- insert(StringRef KeyEqValue) - splits KeyEqValue into (key, value)
pair and inserts it into the environment map.
- compose(value_type KeyValue) - takes a map entry and converts in back
into "KEY=VALUE" representation.
With this interface most of the environment-manipulating code becomes
one-liners. The only tricky part was maintaining compatibility in
SBLaunchInfo, which expects that the environment entries are accessible
by index and that the returned const char* is backed by the launch info
object (random access into maps is hard and the map stores the entry in
a deconstructed form, so we cannot just return a .c_str() value). To
solve this, I have the SBLaunchInfo convert the environment into the
"envp" form, and use it to answer the environment queries. Extra code is
added to make sure the envp version is always in sync.
(This also improves the layering situation as Args was in the Interpreter module
whereas Environment is in Utility.)

Summary:
We sometimes need to write to the object file we've mapped into memory,
generally to apply relocations to debug info sections. We've had that
ability before, but with the introduction of DataBufferLLVM, we have
lost it, as the underlying llvm class (MemoryBuffer) only supports
read-only mappings.
This switches DataBufferLLVM to use the new llvm::WritableMemoryBuffer
class as a back-end, as this one guarantees to return a writable buffer.
This removes the need for the "Private" flag to the DataBufferLLVM
creation functions, as it was really used to mean "writable". The LLVM
function also does not have the NullTerminate flag, so I've modified our
clients to not require this feature and removed that flag as well.

r316368 broke this build when it introduced a reference to a pthread
function to the Utility module. This caused cmake to generate an
incorrect link line (wrong order of libs) because it did not see the
dependency from Utility to the system libraries. Instead these libraries
were being manually added to each final target.
This changes moves the dependency management from the individual targets
to the lldbUtility module, which is consistent with how llvm does it.
The final targets will pick up these libraries as they will be a part of
the link interface of the module.
Technically, some of these dependencies could go into the host module,
as that's where most of the os-specific code is, but I did not try to
investigate which ones.

There were a couple of problems with this function on Windows. Different
separators and differences in how tilde expressions are resolved for
starters, but in addition there was no clear indication of what the
function's inputs or outputs were supposed to be, and there were no tests
to demonstrate its use.
To more easily paper over the differences between Windows paths,
non-Windows paths, and tilde expressions, I've ported this function to use
LLVM-based directory iteration (in fact, I would like to eliminate all of
LLDB's directory iteration code entirely since LLVM's is cleaner / more
efficient (i.e. it invokes fewer stat calls)). and llvm's portable path
manipulation library.
Since file and directory completion assumes you are referring to files and
directories on your local machine, it's safe to assume the path syntax
properties of the host in doing so, so LLVM's APIs are perfect for this.
I've also added a fairly robust set of unit tests. Since you can't really
predict what users will be on your machine, or what their home directories
will be, I added an interface called TildeExpressionResolver, and in the
unit test I've mocked up a fake implementation that acts like a unix
password database. This allows us to configure some fake users and home
directories in the test, so we can exercise all of those hard-to-test
codepaths that normally otherwise depend on the host.

So I cleaned up those and added some tests. The only tricky part here
was that regcomp() implementation on darwin did not recognise the empty

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.

Summary:
This replaces all the uses of the __ANDROID_NDK__ define with __ANDROID__. This
is a preparatory step to remove our custom android toolchain file and rely on
the standard android NDK one instead, which does not provide this define.
Instead I rely, on __ANDROID__, which is set by the compiler.
I haven't yet removed the cmake variable with the same name, as we will need to
do something completely different there -- NDK toolchain defines
CMAKE_SYSTEM_NAME to Android, while our current one pretends it's linux.

This is forcing to use Error::success(), which is in a wide majority
of cases a lot more readable.
