If an archive is corrupted (CRC error) retry the download

Browse Source 
Previously the CRC error was quite annoying to recover because
the user needed to manually delete the corrupted file from the
staging folder (without knowing the exact path of the file to
remove).

Now the IDE tries autonomously to resolve the situation by
removing the file and downloading it again.

Fixes #5394 #4303

* Fixed regression on command line upload.
* Bugifx installing libraries from command line: the IDE tries to update the libraries index but it
didn't use it straight away (this caused issues mainly on CI environments)
* Libraries and Boards Managers: if a download error happens (CRC error) the IDE tries to download the file again
without the need to remove the corrupted file manually.
[core]
* avr: set default values for "upload.verify" and "program.verify" (allows compatibility with older IDE). Thanks @per1234
