fetch2/__init__: Disable pseudo in runfetchcmd()
If a fetcher, e.g., git, is run when pseudo is active it will think it is running as root. If it in turn uses ssh (as git does), ssh too will think it is running as root. This will cause it to try to read root's ssh configuration from /root/.ssh which will fail. If ssh then needs to ask for credentials it will hang indefinitely as there is nowhere for it to ask the user for them (and even if there was it would not access the correct private keys). The solution to the above is to temporarily disable pseudo while executing any fetcher commands. There should be no reason for them to be executed under pseudo anyway so this should not be a problem. RP Ammendum: We finally did get more information about how to reproduce this problem, something needs to trigger bb.fetch2.get_srcrev() in a pseudo context, for example when AUTOREV is in use or the recipe doesn't have a defined SRCREV. That SRC_URI needs to be using protocol=ssh. This would trigger an ls-remote of the remote repo and if that happens under pseudo, the wrong ssh credentials may be attempted which can hang.
