Series trace2: discard new traces if the target directory contains too many files | expand

Commit Message

Move the description of trace2's target-directory behavior into the
shared trace2-target-values file so that it is included in both the
git-config and api-trace2 docs. Leave the SID discussion only in
api-trace2 since it's a technical detail.
