as seen at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113

d88fa5ebe4 Adds windows build (#1040) 
* fixes windows compilation,
adds signal impl for windows,
adds free space usage for windows,
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/70
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1036

NOTE victoria metrics database still CANNOT work under windows system,
only vmagent is supported.
To completly port victoria metrics, you have to fix issues with separators,
parsing and posix file removall

* rollback separator

* Adds windows setInformation api,
it must behave like unix, need to test it.
changes procutil

* check for invlaid param

* Fixes posix delete semantic

* refactored a bit

* fixes openbsd build

* removed windows api call

* Fixes code after windows add

* Update lib/procutil/signal_windows.go

b8a5ee2e93 lib/{mergeset,storage}: allow merging smaller number of small parts 
While this may increase CPU and disk IO usage needed for background merge,
this also recudes CPU usage during queries in production. This is because
such queries tend to read recently added data and it is better to have lower number
of parts for such data in order to reduce CPU usage.

The filter arg has been removed in the commit c7ee2fabb8
because it was preventing from caching the number of matching time series per each tf.

Now the cache contains duration for tf execution, so the filter shouldn't break such caching.
