Once we do this, add support for VerifySig to pactest. We just check if

of VerifySig. The default is Never. pacman uses Always by default but
this is not suitable for pactest.

Noted in FS#23342. When the user attempts to install an ignored package
and answers no when asked whether to install it, pacman bails out with:
"error: target not found: packagename"
This is because satisfiers are not found for the package and execution
continues to process_group(), where the package is treated as a group
(which does not exist).
In addition, test ignore006.py is updated with PACMAN_RETCODE=0 since
saying no to installing an ignored package should not be considered an
error.

This makes all the pacman developers' jobs harder as we have to switch
files whenever running multiple pacman versions and are using newly
introduced options. Instead of erroring out, print warnings and continue
on.
This patch also fixes a const-correctness issue. We immediately cast a
'const char *' to a 'char *' in setrepeatingoption(), which is just
plain wrong as we manipulate the underlying string. Fix the types and
remove the now unnecessary variable.
Finally, a few messages change here for consistency and clarity and
because we continue parsing rather than bailing out on a problem.

Note that there is a behavior change here : if the same package name
appeared several times in the target list, the alpm_add_target interface
chooses the new package, while alpm_add_pkg returns PKG_DUP.
I don't see why we cannot unify the behavior of -S and -U, and just
choose one behavior that applies to both.
Otherwise, it's always possible to handle these different behaviors in
the frontend, it just requires more work.
Signed-off-by: Xavier Chantry <chantry.xavier@gmail.com>
This uses the new public functions to handle targets from the frontend,
like it used to be :
1) alpm_find_dbs_satisfier to find (optionally versioned) package or
provision
2) alpm_find_grp_pkgs to find members for a groups
3) alpm_add_pkg to finally add the pmpkg_t from 1 or 2
Of course, this adds more code to the frontend, but it completely
deprecates sync_target and sync_dbtarget interfaces.
This all-in-one interfaces felt wrong and left no control to the
frontend. A good frontend should just use alpm_add_pkg, with pkg coming
from alpm_db_get_pkg (for normal targets), alpm_find_dbs_satisfier (for
versioned provisions) or alpm_find_grp_pkgs (for groups).
This also opens the way to provide a better group handling in pacman
without constraint from libalpm and callbacks.
In ignore006, only the retcode changes, because no package was found to
satisfy the target (the only possible package is ignored).

If there are multiple providers in one db, pacman used to just stop at
the first one (both during dependency resolution or for pacman -S
'provision' which uses the same code).
This adds a new conversation callback so that the user can choose which
provider to install. By default (user press enter or --noconfirm), the
first provider is still chosen, so for example the behavior of sync402
and 403 is preserved. But at least the user now has the possibility to
make the right choice in a manual run.
If one of the provider is already installed, it is picked for
reinstall/upgrade, so that provision 002/003 pactest now pass.

Clean up some of the code by doing less string copying and printing. This is
accomplished by either doing it after we know we need it, or taking
advantage of the fact that some strings never change such as the root
directory prefix. Also, fix an issue where a file at the root level (e.g.
/foobar) could not be queried.
End result is a much faster user experience when combined with the
mbasename() changes. These timings are for looking up 113 files in /etc/,
some of which are owned and some which are not.
