Debugger (and some friends): 64 bit fixes

Expose the stack pointer and frame pointer via CPUState.

* Register:
- Added a type constant describing the format of the register value.
- Added flag "is callee-preserved" indicating whether the ABI requires the
register to be preserved by a called function.
* CpuState: Added SetRegisterValue(), made GetRegisterValue() const.
* Added RegisterMap interface for mapping register indices between different
models.
* Architecture:
- Added CreateCpuState() version to create a clean CpuState.
- Added GetDwarfRegisterMaps(), which returns to RegisterMaps, converting
from and to DWARF register indices.
- Added ReadValueFromMemory() reading a value from the target team's memory.
The value type is specified by a type constant and the value return via a
BVariant.
- CreateStackTrace: No longer decide whether to adjust the instruction pointer
of the previous CPU state depending on who created the CPU state. Instead
compare it with the return address of the next frame. If they are equal it
obviously has to be adjusted.

* Added StackFrame classification as syscall frame and added correct
identification for x86.
* For non-top stack frames adjust the instruction pointer so that it points to
the calling function instead of the return address.
* SourceView: Consider a syscall frame a non-top frame (the arrow is drawn
differently).

* Added DebuggerInterface::GetSymbolInfos() to get the symbols for an image.
* Added the beginnings of the debug info abstraction. Currently we can only load
the symbols via the debugger.
* Added a job to retrieve debug info for an image. Extended the GetStackTraceJob
to support waiting for image debug info to be loaded.
* Extended ImageInfo by text/data address and size.
* Removed StackFrameX86 and made StackFrame a simple non-polymorphic class
featuring all the needed data. The really architecture-dependent is in the
referenced CpuState already. Added Image* and FunctionDebugInfo* attributes,
referring to the image respectively debug info for the function hit by the
instruction pointer.
* Switched StrackTrace's StackFrame management from DoublyLinkedList to
BObjectList. This makes it more comfortable to use.
* Changed the code for creating stack traces:
- The creation of the StackTrace object and the main loop to collect the
frames are now located in the no longer virtual
Architecture::CreateStackTrace().
- The decision how to create a StackFrame is based on the instruction pointer.
If it hit a function for which debug info is available, the respective
DebugInfo::CreateStackFrame() is used, otherwise we fall back to the new
virtual Architecture::CreateStackFrame().
* Adjusted the stack trace view to also show function names (mangled ATM).

Renamed Variant to BVariant and moved it to libshared.a.

Some work towards getting stack traces:
* Added a virtual Architecture::CreateStackTrace() and added a basic
implementation in ArchitectureX86. Fleshed out StackTrace/StackFrame a bit
and added StackFrameX86. This needs to be organized differently, though, so
that we can get the maximum available information for each stack frame,
depending on what info is available for the respective function.
* Added job to get the stack trace for a thread.
* Added stack trace related handling in TeamDebugger. Reorganized the thread
state/CPU state/stack trace change handling a bit -- we're using a
Team::Listener now, and do things asynchronously.
* Added a StackTraceView to display the stack trace of the current thread. No
function name available yet, otherwise working fine.

More work on the architecture abstraction, particularly regarding information
about what registers the architecture has and how to get them from the CpuState.
Implemented the respective x86 part.
