lib/protoparser/native: fixes parseStream dead-lock (#2423) 
previously, if native block cannot be unmarshaled, wg.Done wasn't called by unmarshal work.
It leads to connection blocking and possible dead-lock at client side

vmctl verify-blocks command (#2390) 
* lib/protoparser: changes ParseStream for native format
uses reader instead of http.Request
updates app/vmagent and app/vmagent method usage

* app/vmctl: add verify-block subcommand
it allows to check exported from VictoriaMetrics data block in native format
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2362

Update app/vmctl/README.md

lib/bytesutil: split Resize() into ResizeNoCopy() and ResizeWithCopy() functions 
Previously bytesutil.Resize() was copying the original byte slice contents to a newly allocated slice.
This wasted CPU cycles and memory bandwidth in some places, where the original slice contents wasn't needed
after slize resizing. Switch such places to bytesutil.ResizeNoCopy().

Rename the original bytesutil.Resize() function to bytesutil.ResizeWithCopy() for the sake of improved readability.

Additionally, allocate new slice with `make()` instead of `append()`. This guarantees that the capacity of the allocated slice
exactly matches the requested size. The `append()` could return a slice with bigger capacity as an optimization for further `append()` calls.
This could result in excess memory usage when the returned byte slice was cached (for instance, in lib/blockcache).

lib/protoparser/prometheus: optimize GetRowsDiff() function

since the provided profile shows that the majority of CPU and memory is spent in this function
during `streamParse` when `-promscrape.noStaleMarkers` wasn't set.

f3e89754a9 lib/promscrape: reduce CPU usage for common case when calculating scrape_series_added metric 
Also reduce CPU usage when applying `series_limit` to scrape targets with constant set of metrics.

The main idea is to perform the calculations on scrape_series_added and series_limit
only if the set of metrics exposed by the target has been changed.
Scrape targets rarely change the set of exposed metrics,
so this optimization should reduce CPU usage in general case.

Previously VictoriaMetrics couldn't parse the following metric

    foo{bar="baz"} 123 # exemplar here

This commit fixes this. Note that VictoriaMetrics ignores the exemplar as for now.
