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.

The ldconfig binary is not guaranteed to be in /sbin. Change to calling
just "ldconfig" rather than using the full path.
This removed the check that the ldconfig binary exists. However, it is
a reasonable assumption that it will exist if its configuration file
does.

This makes us more robust to utilities changing paths. There is no

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

There is duplicated code in the util.c files in the libalpm and pacman
source code. Split this into a separate file so that it can be shared
via a symlink. This prevents code divergence between the two code bases.
Also, move mbasename and mdirname from pacman/util.c into util-common.c
in preparation for the following patch that uses them to add an extension
to pacsave files.

The warning given for a signature timstamp being in the future compared
to the system time stated the opposite.
Also, move this warning to debug output. It is useless in its current
form as the package or database that is giving the error is not
mentioned and so other debug output is needed to find the offending
signature.

This is a bug that has been around since at least 2007. On a package
upgrade (either by -S or -U) a new directory could overwrite any file.
This is caused by the filelist difference calculation ignoring all
directories and thus no new directories were checked for conflicting
files on the filesystem.

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.

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.

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.

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
