25ec63dbf5 libdebugger: Add string setting type.
- Needed in order to properly implement a settings description for
  a remote interface.

a9d53d9e7e Debugger: Fix regression introduced in hrev50534.
FunctionInstance:
- Add new state FUNCTION_SOURCE_SUPPRESSED. This signals that the user
  explicitly forced disassembly to be loaded despite source code being
  available.

LoadSourceCodeJob:
- When forced to disassembly, use the above suppressed state accordingly.

SourceView/TeamWindow/TeamDebugger:
- Adjust to take new state into account as needed.

TeamDebugInfo::GetActiveSourceCode:
- When looking at a function to decide whether to return line information
  based on source or disassembly, first examine the source code state. If
  the source has never been loaded for that function, but we have it available,
  set it on the function at that point. This lazily addresses the fact that
  LoadSourceCodeJob is called on behalf of a specific function, and
  consequently only sets the source code onto that function, and not all others
  present in the same file. This allows us to differentiate between the case
  where a function doesn't have source code available at all, versus a function
  that has simply been forced to disassembly view at this point in time.

The primary symptom of the above issue was that attempting to set a breakpoint
outside of the currently active function, but within the same file would result
in the breakpoints view indicating that the breakpoint was at line 0 rather
than the appropriate line, and breakpoints would also not be drawn in the
source view for such locations.

Thanks to Humdinger for the heads up!

b65adbdfbc Debugger: Fix #12940.
- Add new interface TeamFunctionSourceInformation. Currently this
  exposes a single function allowing one to query for the currently
  active source code given a FunctionDebugInfo instance.
- Implement TeamFunctionSourceInformation on TeamDebugInfo.
- Pass TeamFunctionSourceInformation to Dwarf{Team,Image}DebugInfo.
  In turn, make use of it in DwarfImageDebugInfo::GetStatement() in
  order to determine whether to return the corresponding assembly
  or source statement.

With this piece of information, the debugger is now correctly able to
determine that the user is currently looking at disassembly despite debug
info being available, and consequently adjust its stepping behavior based on
that. Previously, the source code statement was always used, leading to it
not being possible to single step assembly lines in such a circumstance
without manually using run to cursor.

Other related cleanups:
- TeamDebugInfo now inherits BReferenceable directly, rather than relying on
  indirectly inheriting it from TeamTypeInformation.
- Remove BReferenceable from TeamTypeInformation. The latter is only an
  interface anyways, and inheriting that base class from multiple locations
  was causing GCC5 trouble when resolving BReference<TeamDebugInfo>, even
  when virtual inheritance was used.

9c9c24ce08 libdebugger: Add accessor for cpu state size.
Architecture:
- Store and provide accessor for the size in bytes of the low-level
  debug_cpu_state size of the respective target CPU. Adjust subclasses
  to pass in the appropriate size information.

05fc1277c4 Debugger: Fix team restart request.
UserInterface:
- Add Clone() function to set of required virtuals. This asks the subclass
  to create a new instance of its respective type.

{CommandLine,Graphical,Report}UserInterface:
- Implement the above function.

TeamDebugger:
- Add accessor for the currently active UI.

TargetHostInterface:
- Set correct request type when setting up the options for a team restart.
- Ask the TeamDebugger for its user interface and clone it in order to fill
  in that aspect of the debug options. This fixes a regression introduced in
  commit 880a64, which inadvertently resulted in team restarts no longer
  working.

fce4895d18 Debugger: Split into core library and application.
- Add subfolder src/kits/debugger which contains the debugger's core
  functionality and lower layers. Correspondingly add headers/private/debugger
  for shared headers to be used by clients such as the Debugger application
  and eventual remote_debug_server. Adjust various files to account for
  differences as a result of the split and moves.
- Add libdebugger.so to minimal Jamfile.
