FunctionInstance does now also have a (DisassembledCode) source code
attribute. Function keeps its attribute, but it explicitly is a
FileSourceCode now.
* SourceCode:
- Removed GetStatementAtLocation(). Instead DisassembledCode has a
StatementAtLocation() now. As well as a StatementAtAddress() and
StatementAddressRange(). Rather cast to the subclass (in two instances)
instead of having those methods in the base class. In most cases we already
have the subclasses now, anyway.
- Added Lock()/Unlock(), which are implemented in FileSourceCode. The
statement ranges are no longer immutable, so we have to lock.
* TeamDebugModel:
- Revived GetBreakpointsInAddressRange().
- GetBreakpointsForSourceCode(): Optimized for DisassembledCode and fixed
in the FileSourceCode case. We need to compare with the functions' source
file instead of their source code, since they might not have the source
code set yet. Fixed two instances of the same problem in SourceView. Setting
breakpoints in functions that have no associated source code yet, works now.
* Team:
- GetStatementAtAddress(): Optimized by using the DisassembledCode, if
available.
- GetStatementAtSourceLocation(): If the supplied source code is
DisassembledCode, we have to get the statement from it directly, since
we can't get that information from the image debug info.
* TeamDebugInfo: Added LoadSourceCode() and DisassembleFunction(), the new way
to get FileSourceCode respectively DisassembledCode. SpecificTeamDebugInfo
has lost LoadSourceCode() and gained service methods AddSourceCodeInfo() and
ReadCode(). This avoids unnecessary code duplication in the subclasses.
Moreover it allows for joining source location info source files from
different images (and compilation units) -- interesting for inline functions
in headers.
* Adjusted LoadSourceCodeJob and TeamDebugger::FunctionSourceCodeRequested()
accordingly.

a good part of the source tree, so I rather get those changes into the
repository before continuing.
The general aim of the work is to deal with multiple instances of the same
function, e.g. inlined or non-inlined inline functions or those weird duplicates
gcc (4 at least) seems to be generating for no apparent reason.
* Added classes FunctionInstance (wrapping FunctionDebugInfo) and Function.
FunctionInstance represents a physical instance of a function (e.g. inlined
function at a particular address). A Function collects all FunctionInstances
referring to the same source code location.
* Moved the SourceCode property from FunctionDebugInfo to Function accordingly.
* Since SourceCode is no longer associated with a concrete function instance,
several methods dealing with statements have been removed and the
functionality has been provided through other means (e.g. TeamDebugModel or
SpecificImageDebugModel). This part is not yet completed.
* Introduced UserBreakpoint and UserBreakpointInstance. The user sets a
breakpoint at a source code location, which is represented by a
UserBreakpoint. Since that source location can be mapped to one address per
instance of the respective function, UserBreakpoint has a
UserBreakpointInstance per such function instance, which in turn refers to a
Breakpoint (an actual breakpoint at an address).
* Adjusted Breakpoint, BreakpointManager, and TeamDebugger accordingly.

* Created "types" subdirectory for basic types and moved Types.h,
SourceLocation, TargetAddressRange there.
* Added TargetAddressRangeList, representing a list of address ranges.
* Array: Added copy constructor and assignment operator.
* Added DwarfFunctionDebugInfo.
* ElfFile: Also read the program headers and provide access to the segment
information.
* DWARF:
- Some work on DIECompileUnitBase and DIESubprogram to handle attributes we
need.
- Added DwarfUtils class which provides static utility methods. Currently some
to get DIE names. Only provisionally implemented yet.
- Read range list attribute values from the .debug_ranges section. Extended
AttributeValue to handle them correctly (ref-counting).
* DwarfImageDebugInfo:
- Implemented GetFunctions() for real, i.e. we return functions for all
subprogram debug info entries we find (those that refer to actual
functions, that is).
- Implemented the fallback part of LoadSourceCode() (reading the code from the
file and disassembling it).
Things should hopefully work as before, just a bit slower and with less accurate
function names, if DWARF debug info is available. Promising, eh? ;-)

Extended the event mechanism respectively.
* Added support to SourceView to display breakpoints and manipulate them.
* Extended TeamDebugger to install/uninstall breakpoints.
