Yay's dependency resolving takes provides into account. When upgrading
AUR package 'foo', if a repo package provides 'foo' then yay would get
confused and pull in the package providing 'foo' instead of the AUR
package.
This commit ensures AUR upgrades always exclusively check the AUR.
This is simply implemented by looking up against all the args. No
conflicts are checked such as using -Ss and -Si at the same time or using
-u with -D.
Normaly we only pass --config to pacman if the user specifies it on the
command line. Otherwise we let pacman use it's default config location.
If the user has changed pacmanconf in Yay's config file then this could
cause a miss match between the config we use to init alpm and the config
pacman is using.
This allows us to support the Upgrade Usage option as well as relying on
alpm's logic instead of coming up with out own.
It is possible that this could lead to showing replaces in the upgrade
menu.
Bash seperates on whitespace, so the fish completion file
actually works for bash and zsh. So remove the concept of shells
entirley and just use the singular aur_sh.cache file.
If for some reason output without the repository data is needed, the
user could always just pipe it into awk like so
`yay -Pc | awk '{print $1}'`. Or perhaps a --quiet option could be added
where yay will strip the output itself.
The completion cache now updates when installing AUR packages. This is
done as a goroutine with no wait groups. This ensures the program will
never hang if there is a problem.
The completion is stil updated during -Pc but as long as an AUR package
has been installed recently it should not need to update.
The cache will now also wait 7 days instead of 2 before refreshing.
A refresh can be forced using -Pcc.
Currently we do not handle -Sp, this leads to yay trying a proper
install and failing. So instead pass it to pacman and exit. Ideally we
would extend -Sp to include AUR packages but for now don't bother.
