AOSP: libext2fs: merge contiguous data blocks when writing to sparse file

Sparse IO manager allocates one block at a time. This creates many
blocks in sparse file even though most of them are contiguous. As a
result, fastboot is extremely slow writing that many blocks. Merging
contiguous blocks reduces block count and flash time significantly.
