WARNING: O(N) cost

Call this to start a commit. this writes the new segments file, but writes an invalid checksum at the end, so that it is not visible to readers. Once this is called you must call #finishCommit to complete the commit or #rollbackCommit to abort it.

Note: #changed() should be called prior to this method if changes have been made to this SegmentInfos instance

Remove the SegmentCommitInfo at the provided index.

WARNING: O(N) cost

Replaces all segments in this instance, but keeps generation, version, counter so that future commits remain write once.
