sync:
As pointed out by Andrew Gregory there could be an error when adding
duplicates if they are two separate packages with the same name. Add a
check in alpm_add_pkg() to test whether the duplicate is actually the
same package, and if so, log a debug message and return success to skip
the package. If the duplicate is a different package return
ALPM_ERR_TRANS_DUP_TARGET and treat that error just like any other error
in pacman.
remove:
Change alpm_remove_pkg() to just log a debug message and return success
to skip duplicates. Remove the handling of ALPM_ERR_TRANS_DUP_TARGET in
pacman.
Also fixes FS#49377.

Many of these are pointless (e.g. there is no need to explicitly turn on
spellchecking and language dictionaries for the manpages by default).
The only useful modelines are the ones enforcing the project coding
standards for indentation style (and "maybe" filetype/syntax, but
everything except the asciidoc manpages and makepkg.conf is already
autodetected), and indent style can be applied more easily with
.editorconfig

Attempting to compile pacman with gcc8 results in several warnings like:
remove.c: In function ‘unlink_file.isra.4’:
remove.c:407:34: warning: ‘.pacsave.’ directive output may be truncated writing 9 bytes into a region of size between 1 and 4096 [-Wformat-truncation=]
Fix by adding checks to error out if snprintf tries to reserve a
truncated filename. Because the return values are checked, gcc delegates
the truncation response to our code instead of throwing warnings.

If the user replaces a directory with a symlink, libalpm would get
confused because the trailing slash causes system calls to resolve the
symlink. This leads to errors and a misleading message during upgrades.
Even though libalpm does not support this, it should not be giving
misleading errors.
Also adds an overflow check.

ALPM still adds a warning to the log, but doesn't emit an event about
said warning, instead using a specific event to let the frontend what
happened/how to inform the user.
Note that there are 2 cases for installing a .pacnew file, to not
overwrite user changes and because file is in NoUpgrade. In the later case
the warning was a bit different: it happened before and said "extracting"
instead of "installed." Now both happen after and are phrased the same.

Instead of using two void* arguments for all events, we now send one
pointer to an alpm_event_t struct. This contains the type of event that
was triggered.
With this information, the pointer can then be typecasted to the
event-specific struct in order to get additional arguments.

This ensures that important events will be logged and consistent
regardless of the frontend. The need for global context in the event
callback is also removed. The event is logged before any post_* scripts
run, so this also moves the post_* script output underneath the event in
the log.

Detecting indirect dependencies by traversing a package's entire
dependency tree is prohibitively slow for larger transactions. Instead
add local packages to the dependency graph. This additionally requires
delaying dependency ordering for sync operations so that removed
packages may be excluded from dependency detection.
tests/sync012.py was also updated to ensure that the dependency cycle
was actually detected.

Although technically correct, this results in my system taking ~30 seconds
to resolve all filelists when removing a package that has a directory not
owned by any package. The check for if any package own the empty directory
is a rare enough occurance, and it will be even rarer when that directory
has a directory symlink in its path, so just revert this at this stage.

alpm_filelist_contains was being used to search for resolved paths, but
searching in the unresolved paths, causing it to miss matches. We
always search unresolved paths and search the resolved paths if
available because _alpm_filelist_resolve is not public and requires
a context handle, so it can't be called from alpm_filelist_contains.

Arch Linux typically runs into this with /sys when upgrading the
filesystem package in build chroots, but LXC users might also run into
this, since their /sys is shared from the host and must, for security
reasons, be mounted RO.
I've neglected to add any tests for this because they would require root
in order to run. Current tests all pass with this patch and I've
confirmed the desired behavior in a VM. Incidentally, the first hunk of
this patch (skipping can_remove_file checks for directories) resolves the
case of API mountpoints being removed since they eventually fall into
unlink_file and fail with "contains files". However, this patch should
still be the Right Thing To Do™, as we can't possibly remove a directory
that is also a mountpoint.

Teach pacman to save backup files with extension .pacsave.n, where n is a
positive integer. The current backup file shall be saved as <name>.pacsave,
while existing .pacsave.n files will be renamed to <name>.pacsave.n+1
Example:
1. You have subversion installed in your local repo. /etc/conf.d/svnserve
is a file to be backed up. It contains local modifications
2. You remove subversion from your repo. /etc/conf.d/svnserve is backed up as
/etc/conf.d/svnserve.pacsave
2. You install subversion again
3. You edit /etc/conf.d/svnserve
4. You remove subversion. The existing /etc/conf.d/svnserve.pacsave is renamed
to /etc/conf.d/svnserve.pacsave.1 and /etc/conf.d/svnserve is backed up as
/etc/conf.d/svnserve.pacsave

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.
