The file permissions in our cross platform packages were all over the
place. Problems included:
- Executable text files
- Executable MSIL files
- Files not readable by world or group
In addition to just looking bad, it could cause problems in cases where
someone takes the tarballs and copies them to a global location (as
root) because now the deps file was not readable by non root users.
Add an additional step when setting everything up to put sensible
permissions on everything before building os specific packages and
tarballs.
Fixes#2004
dotnet host muxer does not support pre-release CLI SDK when no global.json
file is present. So fixing the CLI layout to be in production version
layout. THIS IS A TEMP HACK.
As a part of Package init create all the SharedFx, SharedHost and CLI SDK
layouts. This way all other package targets can take a dependency only on
InitPackage.
