It's always hard to remember when to include this file, and
when you do include it it's hard to remember what preprocessor
check it needs to be behind, and then you further have to remember
whether it's windows.h or win32.h which you need to include.
This patch changes the name to PosixApi.h, which is more appropriately
named, and makes it independent of any preprocessor setting.
There's still the issue of people not knowing when to include this,
because there's not a well-defined set of things it exposes other
than "whatever is missing on Windows", but at least this should
make it less painful to fix when problems arise.
This patch depends on LLVM revision r278170.

Summary:
This removes the last usage of Platform plugins in lldb-server -- it was used for launching child
processes, where it can be trivially replaced by Host::LaunchProces (as lldb-server is always
running on the host).
Removing platform plugins enables us to remove a lot of other unused code, which was pulled in as
a transitive dependency, and it reduces lldb-server size by 4%--9% (depending on build type and
architecture).

Summary:
The AST contexts are not needed in the server components, and the clang context in particular
pulls in large parts of clang into the binary. Simply removing these two calls reduces the
lldb-server size by about 50%--80%, depending on the architecture and build type.
This should not impact the client parts as the same calls are already present in
SystemInitializerFull.

PDB is Microsoft's debug information format, and although we
cannot yet generate it, we still must be able to consume it.
Reason for this is that debug information for system libraries
(e.g. kernel32, C Runtime Library, etc) only have debug info
in PDB format, so in order to be able to support debugging
of system code, we must support it.
Currently this code should compile on every platform, but on
non-Windows platforms the PDB plugin will return 0 capabilities,
meaning that for now PDB is only supported on Windows. This
may change in the future, but the API is designed in such a way
that this will require few (if any) changes on the LLDB side.
In the future we can just flip a switch and everything will
work.
This patch only adds support for line tables. It does not return
information about functions, types, global variables, or anything
else. This functionality will be added in a followup patch.

Summary:
I've run into an issue when running unit tests, where the underlying problem turned out to be
that we were creating Timer objects (through several layers of indirection) without calling
Timer::Initialize. Since Timer's thread-local storage was not properly initialized, we were
overwriting gtest's own thread-local storage, causing test failures.
Instead of requiring that every test calls Timer::Initialize(), I remove the function altogether:
The thread-local storage can be initialized on-demand, and the g_file variable initialized to
stdout and never changed, so I have simply removed it.

This cleans up type systems to be more pluggable. Prior to this we had issues:
- Module, SymbolFile, and many others has "ClangASTContext &GetClangASTContext()" functions. All have been switched over to use "TypeSystem *GetTypeSystemForLanguage()"
- Cleaned up any places that were using the GetClangASTContext() functions to use TypeSystem
- Cleaned up Module so that it no longer has dedicated type system member variables:
lldb::ClangASTContextUP m_ast; ///< The Clang AST context for this module.
lldb::GoASTContextUP m_go_ast; ///< The Go AST context for this module.
Now we have a type system map:
typedef std::map<lldb::LanguageType, lldb::TypeSystemSP> TypeSystemMap;
TypeSystemMap m_type_system_map; ///< A map of any type systems associated with this module
- Many places in code were using ClangASTContext static functions to place with CompilerType objects and add modifiers (const, volatile, restrict) and to make typedefs, L and R value references and more. These have been made into CompilerType functions that are abstract:
class CompilerType
{
...
//----------------------------------------------------------------------
// Return a new CompilerType that is a L value reference to this type if
// this type is valid and the type system supports L value references,
// else return an invalid type.
//----------------------------------------------------------------------
CompilerType
GetLValueReferenceType () const;
//----------------------------------------------------------------------
// Return a new CompilerType that is a R value reference to this type if
// this type is valid and the type system supports R value references,
// else return an invalid type.
//----------------------------------------------------------------------
CompilerType
GetRValueReferenceType () const;
//----------------------------------------------------------------------
// Return a new CompilerType adds a const modifier to this type if
// this type is valid and the type system supports const modifiers,
// else return an invalid type.
//----------------------------------------------------------------------
CompilerType
AddConstModifier () const;
//----------------------------------------------------------------------
// Return a new CompilerType adds a volatile modifier to this type if
// this type is valid and the type system supports volatile modifiers,
// else return an invalid type.
//----------------------------------------------------------------------
CompilerType
AddVolatileModifier () const;
//----------------------------------------------------------------------
// Return a new CompilerType adds a restrict modifier to this type if
// this type is valid and the type system supports restrict modifiers,
// else return an invalid type.
//----------------------------------------------------------------------
CompilerType
AddRestrictModifier () const;
//----------------------------------------------------------------------
// Create a typedef to this type using "name" as the name of the typedef
// this type is valid and the type system supports typedefs, else return
// an invalid type.
//----------------------------------------------------------------------
CompilerType
CreateTypedef (const char *name, const CompilerDeclContext &decl_ctx) const;
};
Other changes include:
- Removed "CompilerType TypeSystem::GetIntTypeFromBitSize(...)" and CompilerType TypeSystem::GetFloatTypeFromBitSize(...) and replaced it with "CompilerType TypeSystem::GetBuiltinTypeForEncodingAndBitSize(lldb::Encoding encoding, size_t bit_size);"
- Fixed code in Type.h to not request the full type for a type for no good reason, just request the forward type and let the type expand as needed

Previously embedded interpreters were handled as ad-hoc source
files compiled into source/Interpreter. This made it hard to
disable a specific interpreter, or to add support for other
interpreters and allow the developer to choose which interpreter(s)
were enabled for a particular build.
This patch converts script interpreters over to a plugin-based system.
Script interpreters now live in source/Plugins/ScriptInterpreter, and
the canonical LLDB interpreter, ScriptInterpreterPython, is moved there
as well.
Any new code interfacing with the Python C API must live in this location
from here on out. Additionally, generic code should never need to
reference or make assumptions about the presence of a specific interpreter
going forward.

Summary:
Currently, the local-only path fails about 50% of the tests, which means that: a) nobody is using
it; and b) the remote debugging path is much more stable. This commit removes the local-only
linux debugging code (ProcessLinux) and makes remote-loopback the only way to debug local
applications (the same architecture as OSX). The ProcessPOSIX code is moved to the FreeBSD
directory, which is now the only user of this class. Hopefully, FreeBSD will soon move to the new
architecture as well and then this code can be removed completely.

In an effort to reduce binary size for components not wishing to
link against all of LLDB, as well as a parallel effort to reduce
link dependencies on Python, this patch splits out the notion of
LLDB initialization into "full" and "common" initialization.
All code related to initializing the full LLDB suite lives directly
in API now. Previously it was only referenced from API, but because
it was defined in lldbCore, it would get implicitly linked against
by everything including lldb-server, causing a considerable
increase in binary size.
By moving this to the API layer, it also creates a better layering
for the ongoing effort to make the embedded interpreter replacable
with one from a different language (or even be completely removeable).
One semantic change necessary to get this all working was to remove
the notion of a shared debugger refcount. The debugger is either
initialized or uninitialized now, and calling Initialize() multiple
times will simply have no effect, while the first Terminate() will
now shut it down no matter how many times Initialize() was called.
This behaves nicely with all of our supported usage patterns though,
and allows us to fix a number of nasty hacks from before.
