This commit adds support for column breakpoints to lldb-dap.
To do so, support for the `breakpointLocations` request was
added. To find all available breakpoint positions, we iterate over
the line table.
The `setBreakpoints` request already forwarded the column correctly to
`SBTarget::BreakpointCreateByLocation`. However, `SourceBreakpointMap`
did not keep track of multiple breakpoints in the same line. To do so,
the `SourceBreakpointMap` is now indexed by line+column instead of by
line only.
See http://jonasdevlieghere.com/post/lldb-column-breakpoints/ for a
high-level introduction to column breakpoints.
The don't currently work (and they're also not particularly useful,
since all of the remote stuff happens inside lldb).
This saves us from annotating tests one by one.
assertEquals is a deprecated alias for assertEqual and has been removed
in Python 3.12. This wasn't an issue previously because we used a
vendored version of the unittest module. Now that we use the built-in
version this gets updated together with the Python version used to run
the test suite.
Rename lldb-vscode to lldb-dap. This change is largely mechanical. The
