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.

If a pacakge has a directory symlink (e.g. /lib -> usr/lib), do not
allow it to be removed if any other package is trying to install a
file into that path (e.g. /lib/foo). This is because the local
database can become invalidated if the symlink is removed after the
package with file /lib/foo is installed (sync702.py). If the symlink
is removed before the file is installed (sync701.py), the upgrade is
actually a success, but we can not guarantee the ordering so both
cases should fail.

If we have a symlink to a directory (e.g. /lib -> usr/lib), then
we can not remove it if a local package thinks it has files in the
symlink directory (e.g. /lib/foo), because this will invalidate the
local file database.

With glibc-2.16, using -D_FORTIFY_SOURCE requires that optimization (-O)
be used or it will prodice a warning message. Enable -Werror in our
test for _FORTIFY_SOURCE support to catch when a users specifies CFLAGS
without optimization.
The line to set CFLAGS="" when no CFLAGS are specified (either due to
being unset or geniunely empty) is required as autoconf will use
"-O2 -g" for its tests by defult when CFLAGS is unset, but will not add
them to the CFLAGS used...

74274b5dc3 which added the real_line_size to the buffer struct
didn't properly account for what happens when archive_fgets has to loop
more than once to find the end of a line. In most cases, this isn't a
problem, but could potentially cause a longer line such as PGP signature
to be improperly read.
This patch fixes the oversight and focuses on only calculating the line
length when we hit the end of line marker. The effective length is then
calculated via pointer arithmetic as:
(start_of_last_read + read_length) - start_of_line

When checking if a package owns a directory, it is important to check
not only that all the files in the directory are part of the package,
but also if the directory is part of a package. This catches empty
subdirectories during conflict checking for directory to file/symlink
replacements.

When two packages own an empty directory, pacman finds no conflict when
one of those packages wants to replace the directory with a file or a
symlink. When it comes to actually extracting the new file/symlink,
pacman sees the directory is still there (we do not remove empty
directories if they are owned by a package) and refuses to extract.
Detect this potential conflict early and bail. Note that it is a
_potential_ conflict and not a guaranteed one as the other package owning
the directory could be updated or removed first which would remove
the conflict. However, pacman currently can not sort package installation
order to ensure this, so this conflict requires manual upgrade ordering.

This function is the reverse of human_to_size, and converts integer byte
sizes to human readable SI prefixed values.
A logical extension of this might be to mimic the formatter that pacman
uses and allow a second argument to be passed in which can coerce the
size, rather than reducing until the unit count is below 1024.

Only load filesystem details for the mount points that we're actually
going to write to. This reduces our syscall count considerably. In the
case of installation, we would actually stat every mountpoint twice (an
extra round for download diskspace) which means (on my system) a total
of 60 syscalls to write to 3 partitions when installing the kernel
package. This change reduces the 60 syscalls down to the expected 3.
A slight debug output change is added here to discern between a
mountpoint added to our linked list versus when we actually load the fs
info.
