/**
* Updating the database:
*
* The Update() method takes a series of chunks separated with control data,
* as described in
* http://code.google.com/p/google-safe-browsing/wiki/Protocolv2Spec
*
* It will iterate through the control data until it reaches a chunk. By
* the time it reaches a chunk, it should have received
* a) the table to which this chunk applies
* b) the type of chunk (add, delete, expire add, expire delete).
* c) the chunk ID
* d) the length of the chunk.
*
* For add and subtract chunks, it needs to read the chunk data (expires
* don't have any data). Chunk data is a list of URI fragments whose
* encoding depends on the type of table (which is indicated by the end
* of the table name):
* a) tables ending with -exp are a zlib-compressed list of URI fragments
* separated by newlines.
* b) tables ending with -sha128 have the form
* [domain][N][frag0]...[fragN]
* 16 1 16 16
* If N is 0, the domain is reused as a fragment.
* c) any other tables are assumed to be a plaintext list of URI fragments
* separated by newlines.
*
* Update() can be fed partial data; It will accumulate data until there is
* enough to act on. Finish() should be called when there will be no more
* data.
