e8cd0c9859 Added the infrastructure necessary for plug-ins to be able to add their own settings instead of having settings added to existing ones. In particular "target.disable-kext-loading" was added to "target" where it should actually be specific to the the dynamic loader plugin. Now the plug-in manager has the ability to create settings at the root level starting with "plugin". Each plug-in type can add new sub dictionaries, and then each plug-in can register a setting dictionary under its own short name. For example the DynamicLoaderDarwinKernel plug-in now registers a setting dictionary at:
plugin
    dynamic-loader
        macosx-kernel
            (bool) disable-kext-loading
            
To settings can be set using:

(lldb) settings set plugin.dynamic-loader.macosx-kernel.disable-kext-loading true

I currently only hooked up the DynamicLoader plug-ins, but the code is very easy to duplicate when and if we need settings for other plug-ins.

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.

c859e2d524 Full core file support has been added for mach-o core files.
Tracking modules down when you have a UUID and a path has been improved.

DynamicLoaderDarwinKernel no longer parses mach-o load commands and it
now uses the memory based modules now that we can load modules from memory.

Added a target setting named "target.exec-search-paths" which can be used
to supply a list of directories to use when trying to look for executables.
This allows one or more directories to be used when searching for modules
that may not exist in the SDK/PDK. The target automatically adds the directory
for the main executable to this list so this should help us in tracking down
shared libraries and other binaries.
