Return -1 if a path is too long to resolve or we run out of memory.

This applies to a case such as when /lib is a symlink to /usr/lib. If a
package is installed which contains /lib/libfoo.so, pacman will complain
if this package is then "fixed" to contain /usr/lib/libfoo.so. Since
these have the same effective path and it exists within the same
package, ignore the conflict.
Fixes FS#30681.

File paths are resolved if necessary during inter-package conflict
checks so that packages carrying the same effective file due to
directory symlinks on the filesystem are flagged as conflicting.

If a filename isn't resolved, the original can be used instead of strdup()ing
it.

The _alpm_filelist_resolve function takes a filelist and creates
a list with any symlinks in directory paths resolved.

Detect a conflict between a file/symlink in one package and a directory
in another when both are being installed at once.
A side effect is the creation of conflicts between a directory symlink
and a real directory (e.g lib -> usr/lib in pkg1 and /lib in pkg2).
Given we can not guarantee pkg1 is installed before pkg2, this is a
genuine conflict.

To improve conflict checking, we will need to make these functions
diverge to an extent where having two separate functions will be
preferable.

We have a few of these and might as well gather them together. This also
cleans up the code a bit by using an enum instead of integer values, as
well as makes a "search for file in filelist" function public so
frontends can do better than straight linear search of the filelists.
