Tamas Berghammer 42ecef3b15 Add absolute load address support for the DynamicLoader plugins
The POSIX linker generally reports the load bias for the loaded
libraries but in some case it is useful to handle a library based on
absolute load address. Example usecases:
* Windows linker uses absolute addresses
* Library list came from different source (e.g. /proc/<pid>/maps)

Tamas Berghammer f256184693 Fix [vdso] handling on Android (x86 and aarch64)
* Add in-memory object file handling to the core dynamic loader
* Fix in memory object file handling in ObjectFileELF (previously
  only part of the file was loaded before parsing)
* Fix load address setting in ObjectFileELF for 32-bit targets
  when the load bias is negative
* Change hack in DYLDRendezvous.cpp to be more specific and not to
  interfere with object files with fixed load address

Greg Clayton 751caf65c2 Modified ObjectFile::SetLoadAddress() to now be:
ObjectFile::SetLoadAddress (Target &target,
                            lldb::addr_t value,
                            bool value_is_offset);

Now "value" is a slide if "value_is_offset" is true, and "value" is an image base address otherwise. All previous usage of this API was using slides.

Updated the ObjectFileELF and ObjectFileMachO SetLoadAddress methods to do the right thing.

Also updated the ObjectFileMachO::SetLoadAddress() function to not load __LINKEDIT when it isn't needed and to only load sections that belong to the executable object file.

Steve Pucci 9e02dacddf Factor some methods that were in DynamicLoaderPOSIXDYLD.
Move some code that was in DynamicLoaderPOSIXDLYD into the
base class DynamicLoader.  In the case of UpdateLoadedSections(),
the test to see whether a file is loadable (its address is zero)
is not generally applicable so that test is changed to a more
universally applicable check for the SHF_ALLOC flag on the section.

Also make it explicit that the reading of the module_id in
DynamicLoaderPOSIXDYLD::GetThreadLocalData() is using a hardcoded
size (of module_id) of 4, which might not be appropriate on
big-endian 64-bit systems, leaving a FIXME comment in place.

Greg Clayton 57abc5d6a6 <rdar://problem/13854277>
<rdar://problem/13594769>

Main changes in this patch include:
- cleanup plug-in interface and use ConstStrings for plug-in names
- Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp
- Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging

The plug-in interface changes:

Modified the lldb_private::PluginInterface class that all plug-ins inherit from:

Changed:

virtual const char * GetPluginName() = 0;

To: 

virtual ConstString GetPluginName() = 0;

Removed:

virtual const char * GetShortPluginName() = 0;

- Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names. 
- Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc.

Greg Clayton 7b0992d9cd After discussing with Chris Lattner, we require C++11, so lets get rid of the macros and just use C++11.

Greg Clayton e01e07b6e7 Since we use C++11, we should switch over to using std::unique_ptr when C++11 is being used. To do this, we follow what we have done for shared pointers and we define a STD_UNIQUE_PTR macro that can be used and it will "do the right thing". Due to some API differences in std::unique_ptr and due to the fact that we need to be able to compile without C++11, we can't use move semantics so some code needed to change so that it can compile with either C++.
Anyone wanting to use a unique_ptr or auto_ptr should now use the "STD_UNIQUE_PTR(TYPE)" macro.

Jim Ingham 2995077d8a Add "target.process.stop-on-shared-library-events" setting, and make it work.
Add the ability to give breakpoints a "kind" string, and have the StopInfoBreakpoint
print that in the brief description if set.  Also print the kind - if set - in the breakpoint
listing.
Give kinds to a bunch of the internal breakpoints.
We were deleting the Mac OS X dynamic loader breakpoint as though the id we had stored away was
a breakpoint site ID, but in fact it was a breakpoint id, so we never actually deleted it.  Fixed that.

Greg Clayton 93d3c8339c The DynamicLoader plug-in instance now lives up in lldb_private::Process where
it should live and the lldb_private::Process takes care of managing the 
auto pointer to the dynamic loader instance.

Also, now that the ArchSpec contains the target triple, we are able to 
correctly set the Target architecture in DidLaunch/DidAttach in the subclasses,
and then the lldb_private::Process will find the dynamic loader plug-in 
by letting the dynamic loader plug-ins inspect the arch/triple in the target.

So now the ProcessGDBRemote plug-in is another step closer to be purely 
process/platform agnostic.

I updated the ProcessMacOSX and the ProcessLinux plug-ins accordingly.

Greg Clayton ed8a705cea General command line help cleanup:
- All single character options will now be printed together
- Changed all options that contains underscores to contain '-' instead
- Made the help come out a little flatter by showing the long and short
  option on the same line.
- Modified the short character for "--ignore-count" options to "-i"
