* Introduced SourceCode::LineLengthAt(index) and respective implementations in FileSourceCode and DisassembledCode for getting the cached length of the line at the given index.
* Use LineLengthAt in various places in SourceView::TextView to avoid having to calculate string lengths on the fly.
* Clamp the size of the drag and drop rect to the window size. Otherwise in cases of large selections, said rect would get quite large.
* Add support for double click word and triple click line selection.
* Fix problems with tracking state which would erroneously cause the mouse entering the view while dragging on a scroll bar to initiate a drag and drop if there was selected text.
* Add Select All menu/keyboard shortcut and implement corresponding functionality in SourceView::TextView.

subclasses, though they don't do much yet. SourceCode is now associated with a
SourceLanguage.

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.

- 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.

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