When a package is already partially downloaded in the cache, its download
size will only be of what's left to be downloaded. Since pkg->download_size
is what's used when calculating the total download size for the totaldl
callback, same thing apply.
However, the download progress callback was including this initial size,
which would thus lead to invalid values (and percentage) used in frontends.
That is, the progress bar could e.g. go further than 100%
In the case of pacman, there is a sanity check for different historical
reason (44a57c89), so before the possible "overflow" was noticed, the total
download size/progress reported was wrong. Once caught, the TotalDownload
option was ignored and it would use individual file download values as
fallback instead.

When calling open(), use O_CLOEXEC as much as possible to ensure the
file descriptor is closed when and if a process using libalpm forks.
For most of these cases, and especially in utility functions, the file
descriptor is opened and closed in the same function, so we don't have
too much to worry about. However, for things like the log file and
database lock file, we should ensure descriptors aren't left hanging
around for children to touch.
This patch is inspired by the problem in FS#36161, where an open file
descriptor to the current working directory prevents chroot() from
working on FreeBSD. We don't need this file descriptor in the child
process, so open it (and now several others) with O_CLOEXEC.
