RFC 2616 doesn't forbid a 301 or 302 repsonse from having a body, and
servers exist in the wild that show this behavior. In order to prevent
pacman from showing a progress bar when we aren't actually downloading a
package (and merely following one of these pain in the butt redirects),
capture the server response code in the response header, rather than
waiting to peel it off the handle after the download has finished.

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

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

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.

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.

mountpoint added to our linked list versus when we actually load the fs
