Detailed Description

Class representing a buffer of zero or more diagnostics that
have been reported to a diagnostic_context, but which haven't
yet been flushed.

A diagnostic_buffer can be:

* flushed to the diagnostic_context, which issues
the diagnostics within the buffer to the output format
and checks for limits such as -fmax-errors=, or

* moved to another diagnostic_buffer, which moves the diagnostics
within the first buffer to the other buffer, appending them after any
existing diagnostics within the destination buffer, emptying the
source buffer, or

* cleared, which discards any diagnostics within the buffer
without issuing them to the output format.

Since a buffer needs to contain output-format-specific data,
it's not possible to change the output format of the
diagnostic_context once any buffers are non-empty.

To simplify implementing output formats, it's not possible
to change buffering on a diagnostic_context whilst within a
diagnostic group.

Lazily get the output formats to create their own kind of buffers.
We can't change the output sinks on a context once this has been called
on any diagnostic_buffer instances for that context, since there's no
way to update all diagnostic_buffer instances for that context.
