Create a new "lldb_private::CompilerDeclContext" class that will replace all direct uses of "clang::DeclContext" when used in compiler agnostic code, yet still allow for conversion to clang::DeclContext subclasses by clang specific code. This completes the abstraction of type parsing by removing all "clang::" references from the SymbolFileDWARF. The new "lldb_private::CompilerDeclContext" class abstracts decl contexts found in compiler type systems so they can be used in internal API calls. The TypeSystem is required to support CompilerDeclContexts with new pure virtual functions that start with "DeclContext" in the member function names. Converted all code that used lldb_private::ClangNamespaceDecl over to use the new CompilerDeclContext class and removed the ClangNamespaceDecl.cpp and ClangNamespaceDecl.h files.
Removed direct use of clang APIs from SBType and now use the abstract type systems to correctly explore types.
Bulk renames for things that used to return a ClangASTType which is now CompilerType:
"Type::GetClangFullType()" to "Type::GetFullCompilerType()"
"Type::GetClangLayoutType()" to "Type::GetLayoutCompilerType()"
"Type::GetClangForwardType()" to "Type::GetForwardCompilerType()"
"Value::GetClangType()" to "Value::GetCompilerType()"
"Value::SetClangType (const CompilerType &)" to "Value::SetCompilerType (const CompilerType &)"
"ValueObject::GetClangType ()" to "ValueObject::GetCompilerType()"
many more renames that are similar.

The following functions were the only functions that updates the source file:
SourceManager::File::DisplaySourceLines()
SourceManager::File::FindLinesMatchingRegex()
But there we API calls that were using the SourceManager::File and asking it questions, like "is line 12 valid" and that might respond incorrectly if the source file had been updated.

Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python
after a future patch.
None of the files that were including this header actually depended
on it anyway, so it was just a dead include in every single instance.

The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)
We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

Fixed a crasher in the SourceManager where it wasn't checking the m_target member variable for NULL.
In doing this fix, I hardened this class to have weak pointers to the debugger and target in case they do go away. I also changed SBSourceManager to hold onto weak pointers to the debugger and target so they don't keep objects alive by holding a strong reference to them.

lldb remembers not-found source file, setting target.source-map doesn't make it re-check for it. Now this is fixed. Each time the source path remappings get updated, the modification ID in the PathMappingList gets bumped and then we know the re-check for sources.
llvm-svn: 177125
Made the "--reverse" option to "source list" also be able to use the "--count". This helps us implement support for regexp source list command:
(lldb) l -10
Which gets turned into:
(lldb) source list --reverse --count 10
Also simplified the code that is used to track showing more source from the last file and line.

Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary.
So I defined a new "lldb::offset_t" which should be used for all file offsets.
After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed.
Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections.

last source point listed.
Also fix the setting of the default file & line to the file containing main, when you do a plain "list".

- add new header lldb-python.h to be included before other system headers
- short term fix (eventually python dependencies must be cleaned up)

Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes:
- Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file".
- modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly
- Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was.
- modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile()
Cleaned up header includes a bit as well.

indicate whether inline functions are desired.
This allows the expression parser, for instance,
to filter out inlined functions when looking for
functions it can call.

There were two problems associated with this radar:
1. "settings show target.source-map" failed to show the source-map after, for example,
"settings set target.source-map /Volumes/data/lldb/svn/trunk/test/source-manager /Volumes/data/lldb/svn/trunk/test/source-manager/hidden"
has been executed to set the source-map.
2. "list -n main" failed to display the source of the main() function after we properly set the source-map.
The first was fixed by adding the missing functionality to TargetInstanceSettings::GetInstanceSettingsValue (Target.cpp)
and updating the support files PathMappingList.h/.cpp; the second by modifying SourceManager.cpp to fix several places
with incorrect logic.
Also added a test case test_move_and_then_display_source() to TestSourceManager.py, which moves main.c to hidden/main.c,
sets target.source-map to perform the directory mapping, and then verifies that "list -n main" can still show the main()
function.

Stopped the SymbolFileDWARF::FindFunctions (...) from always calculating
the line table entry for all functions that were found. This can slow down
the expression parser if it ends up finding a bunch of matches. Fixed the
places that were relying on the line table entry being filled in.
Discovered a recursive stack blowout that happened when "main" didn't have
line info for it and there was no line information for "main"

Fix the RegularExpression class so it has a real copy constructor.
Fix the breakpoint setting with multiple shared libraries so it makes
one breakpoint not one per shared library.
Add SBFileSpecList, to be used to expose the above to the SB interface (not done yet.)

Set the default Source File & line to main (if it can be found.) at startup. Selecting the current thread & or frame resets
the current source file & line, and "source list" as well as the breakpoint command "break set -l <NUM>" will use the
current source file.
