The practice of buffering to a tempfile during a pushing contributes massively
to slow V2 push performance perception. The protocol was actually designed to
avoid precalculation, supporting cut-through data push. This means we can
assemble the layer, calculate its digest and push to the remote endpoint, all
at the same time.
This should increase performance massively on systems with slow disks or IO
bottlenecks.

Now scheduler makes order of events pretty random, so I added little
sleeps to make order intact. Also I renamed to test so name better
describes its nature.

This fixes two problems:
1. docker run --device /dev/sda:rw ubuntu bash doesn't work
2. --device /dev/zero:/dev/noro:ro doesn't show clear error message,
but fail when writing to cgroup file.

1. rename it from ValidateMountMode to ValidMountMode
Because it's a function simply check mount mode is valid or not.
2. remove the rw check return value
It's not supposed to be combined into this function, and we already
have a function for that check.

In particular I want to make sure that calling getEnv() when the same
var name appears more than once in the env list that we only pick up
the first one. PR #15182 counts on this
