- Replaced StatementAtLine() by GetStatementLocationRange(), which doesn't
return a statement (i.e. also target addresses), but just a range in the
source code. This can also be implemented by FileSourceCode, which can
therefore be used for more than one instance of a function.
- Added GetStatementAtLocation() which kind of is also a replacement for
StatementAtLine(), but is optional and only provided by
DisassembledSourceCode.
- Added GetSourceFile(), which has to be provided when
GetStatementAtLocation() is not implemented.
- Kicked the statement stuff out of FileSourceCode. It only knows source
ranges, now.
* Team: Added GetStatementAtSourceLocation(), which is the real replacement for
SourceCode::StatementAtLine() in cases where a statement is actually
needed. It uses SourceCode::GetStatementAtLocation(), if available and
otherwise finds a function at the source location, and gets a statement for
one of its instances.
* TeamDebugInfo: Does now manage a source file -> functions map allowing to
look up functions at source file locations.
* DwarfImageDebugInfo:
- Switched the path in the source code hash table key for a LocatableFile,
which is cheaper to hash and to compare.
- Fixed bugs where the relocation delta was ignored.
- Replace a -1 in the SourceLocation column component by 0 to avoid
mismatches.
* SourceLocation: Changed component types from uint32 to int32. Otherwise -1 is
not representable.
Things mostly work as before starting the refactoring to support function
instances. All is not well yet, though. E.g. we don't merge the source code
information for common source files (like headers) provided by different
compilation units (or even images) yet. We need to do that, since the debug
info for a compilation unit only contains line number information for inline
functions (in headers) that are actually used.

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.

* Added StringUtils with string hash functions.
* Added Locatable{Entry,File,Directory} and FileManager classes to manage the
mapping from debug info/target file names to local file names.
* Image does now have a LocatableFile referring to the image's shared object
file. Added listening to location changes of these files to TeamDebugger. No
action is taken yet (should trigger reloading the debug info).

* Added TeamDebugInfo which serves as factory for ImageDebugInfos.
* Added the DWARF code to the build again. It's not used yet, though.

the jobs accordingly.
* Added a view to list the source files and functions for an image.
