Rewrote the logic for pre-filtering files based on timestamps/metadata to be more verbose and well documented.
Fixed an issue where `--check-filetime-only` also checked the file size, which was not present due to the reduced query used to grab only the lastmodified information.
Fixed a problem where the check for existing metadata was wrong and produced a warning.
This fixes#3204
This handles some of #3194
Changed a few things on the way, removing the log process

First attempt at merging all changes from 2016-10-08 to now :/
A simple backup that specifies --deleted-files causes a Fatal error.
Shortened repro steps:
(See Github comment for full repro steps)
>duplicati.commandline.exe backup file://C:\data\local\testchangedfiles\destination "C:\data\local\testchangedfiles\source\\" --encryption-module="none" --no-encryption="true" --dbpath="testchangedfiles.sqlite" --compression-module="zip" --keep-versions=-1 --no-auto-compact="true"
>del source\file6.txt
>duplicati.commandline.exe backup file://C:\data\local\testchangedfiles\destination "C:\data\local\testchangedfiles\source\\" --changed-files="C:\data\local\testchangedfiles\source\file1.txt;C:\data\local\testchangedfiles\source\file2.txt" --deleted-files="C:\data\local\testchangedfiles\source\file6.txt" --encryption-module="none" --no-encryption="true" --dbpath="testchangedfiles.sqlite" --compression-module="zip" --keep-versions=-1 --no-auto-compact="true"
Results in:
Fatal error => Input string was not in a correct format.
System.FormatException: Input string was not in a correct format.

With this patch, backup completes successfully.
- Don't use Vacuum() just before PurgeLogData (which performs vacuum() already)
- Removed unncessary poorly performning query (after optimizing it I found out it's unused)
- Correctly log calls for ExecuteScalarInt64
Now we only look at the timestamp from the previous fileset, instead of for the last time the file was seen.
This should improve lookup times, and thus the running time for backups with many files.
This change means that the following sequence of operations will react differently:
- backup
- delete file
- backup
- undelete file
- backup
Prior to this commit, the undeleted file would be seen with the original timestamp and thus can avoid being scanned for changes.
After this commit, the file will be treated as a new file, even if it has the previous timestamp and will thus be scanned for changes.
An additional switch has been introduced, --check-filetime-only that improves the lookup further by not looking at the metadata or filesize, and thus makes a much lighter call to the database, where fewer tables need to be touched.
Some changes were required for this merge,
now the StreamBlockSplitter process will take in any stream, store the blocks and return the blockset ID.
This makes it compatible with the changes for metadata handling where they support more than a single block of metadata.

- Fixed SQL to create temp table for lookup of last backup's file
entries
- Removed temp table by writing directly to internal lookup struct.
- Direct lookup of single file entries from DB
