The contents of `os.Stat` are rather fitted towards local package pools,
but the method is in the generic PackagePool interface. This moves it to
LocalPackagePool, and the use case of simply finding a file's size is
delegated to a new, more generic PackagePool.Size() method.

In some local tests w/ a slowed down filesystem, this massively cut down
on the time to clean up a repository by ~3x, bringing a total 'publish
update' time from ~16s to ~13s.

While updating mirror, if package file is already in pool path,
field `PoolPath` was left as empty which results in package file
being unavailable later on while publishing.
Local package pool now implements more generic package pool API.
The base idea is to never expose full paths to files, so that other
kinds of package pools (e.g. package pool in S3) could be used to implement
the same interface.
Files get into the pool only using `Import` method. `Import` method is
now more smart, it supports moving files into the pool, it can detect if
files reside on the same filesystem and use hardlinking instead of copying.
This will make direct mirror downloads still as fast as they were with previous
version which was performing download directly to package pool.
New package pool doesn't have two things implemented yet:
1. New file placement according to SHA256 or other configured hash
2. Calculate at least SHA256/MD5 for each imported files.
MD5 would be required for S3/Swift publishing
This is related to #506
As a first step, don't pass MD5 explicitly, pass checksum info object,
so that as a next step we can choose which hash to use.
There should be no functional changes so far.
Next step: stop returning explicit paths from public package pool.
