This allows a frontend to define its own download algorithm so that the
libfetch dependency can be omitted without using an external process.
The callback will be used when if it is defined, otherwise the old
behavior applies.

If the user switches from unstable repo to a stable one, it is quite hard to
sync its system with the new repo (the user will see many "Local is newer
than stable" messages, nothing more). That's why I introduced -Suu, which
treats a sync package like an upgrade, iff the package version doesn't match
with the local one's.
I added a new pactest (sync104.py) to test this, and I updated the
documentation of -Su.

This happens for example if you install a new package, and one of its
backup config file is already on the file system.
If the local file was different, it was saved to .pacorig which is fine.
However if the local file and pkg file were the same, the pkg file
(temporarily extracted as .paccheck) was left on the system.

Additionally pacman can be more verbose when the extraction of the symlink

This fixes FS#14899. When running an -Sp operation without servers
configured for a repository, we would segfault, so add an assert to the
backend method returning the first server preventing a null pointer
dereference.
In addition, add a new error code to libalpm that indicates we have no
servers configured for a repository. This makes -Sy and -S <package>
operations fail gracefully and helpfully when a repo is set up with no
servers, as the default mirrorlist in Arch is provided this way.

"Foo replaces bar" simply means that "foo is a new version of bar".
So this patch refactors the code to use this "rule".
_alpm_sync_sysupgrade now does the following for each local package [bar]
(pseudo-code):
for db in syncdbs {
if(db contains bar) {check if db/bar is an upgrade; break;}
replacers = find(bar replacers in db);
if(replacers!=NULL) {ask_user; break;}
}
Note:
1. Replacers are grouped per repo. If more than one package replace bar in
a repo, all of them are considered ("package set of bar replacers").
2. If repo1/foo1 and repo2/foo2 both replaces bar, only repo1/foo1 is
considered (if repo1 stands before repo2 in pacman.conf). FS#11737 is fixed.
3. It can happen that pacman doesn't consider any replacer, if it found a
literal "earlier", so sync132.py modified accordingly (btw, that situation
should not appear irl).
The new sysupgrade code doesn't use sync_newversion(), so I removed the
"local is newer than repo" message, which was annoying with -Qu and
SyncFirst.

This fixes a bug introduced by my previous changes which changes the
behavior of IgnorePkg/IgnoreGroup to allow the user to remove unresolvable
packages from the transaction. The bug is that the target-list was no
longer being consulted first to resolve dependencies, which means that if
two packages in the sync database satisfied a dependency, and the user
explicitly requested one of those two packages in the sync, the other
package was still being pulled in.
A new test was added, sync993.py, to verify the desired behavior.

pmsyncpkg_t data sructure was removed:
1. pmpkg_t.reason is used instead of pmsyncpkg_t.newreason. (The target
packages come from sync repos, so we can use this field without any
problems. Upgrade transaction also uses this field to store this info.)
2. pmsyncpkg_t.removes was moved to pmpkg_t.removes.
This step requires careful programming, because we don't duplicate packages
when we add them to trans->packages. So we modify sync pkgcache when we
add this transaction-only info to our package. Hence it is important to
free this list when we remove any package from the target list
(remove_unresolvable, remove_conflicts, trans_free), otherwise this could
confuse the new sync transactions (with non-pacman GUI).
Overall, our code became ~100 line shorter, and we can call our helper
functions directly on trans->packages in sync.c, we don't need to maintain
parallel package lists.

From now on _alpm_db_find_fileconflicts() works with upgrade and remove
target lists (like checkdeps), which makes it transaction independent
(we still need a trans param because of the progressbar). This is a small
step towards the universal transaction. So we call this function directly
from sync.c before commiting the remove transaction. This is much safer,
but we can get false fileconflict error alarms in some tricky cases
("symlinks puzzle" etc).
The patch on find_fileconflict looks complex, but it is mainly an
"indent-patch", the new code-part can be found after the
/* check remove list ... */ comment, and I modified something around the
"file has changed hand" case (see comment modifications in the code).
Unfortunately sync.c became more ugly, because we have to create 2 parallel
internal transactions: to avoid duplicated work, upgrade transaction is
used to load package data (filelists). This problem will disappear, when
we finally get rid of internal transactions.

pm_errno.

is always freed in cleanup.)

This reverts commit 9558639d80.
This change was wrong, popen does require /bin/sh in a subchroot.
1) pacman -S lilo -r root
Notice no error
2) rm root/bin/sh ; pacman -S lilo -r root
Notice an error :
error: scriptlet failed to execute correctly
Actually, we already get an explicit error here, when popen is run, so there
is no need to check for bin/sh explicitely.
Besides this check was problematic in some cases. For example, bash itself
has a scriptlet, but only post_install and post_upgrade, no pre_install and
pre_upgrade. However, since bash has a scriptlet, runscriptlet will also be
called before bash is installed. It won't do anything since the scriptlet
has no pre_install function. But if we keep the check, we will still get
"error : no /bin/sh".

This is a bug I noticed 2 years ago :
http://www.nabble.com/Re%3A-logging-output-crazy-to11437357.html#a11479679
I thought I fixed it with 57d77eab32
But the bug was still here. Reading man fork, this part caught my attention:
* The child inherits copies of the parent's set of open file
descriptors. Each file descriptor in the child refers to the same open
file description (see open(2)) as the corresponding file descriptor in the
parent. This means that the two descriptors share open file status
flags, current file offset, and signal-driven I/O attributes (see the
description of F_SETOWN and F_SETSIG in fcntl(2)).
Since the open file descriptors are inherited, it is probably a good idea to
flush them before forking.

The from_md5 and to_md5 fields were a nice extra safety, which would avoid
trying to apply deltas on corrupted package files. However, they are not
strictly necessary, since xdelta should be able to detect that on its own.
The main problem is that it is impossible to compute these informations from
the delta only. So repo-add would not be able to compute the delta entry
based on just the delta file.

Enabled a new prompt to ask the user if they'd like to remove
unresolvable packages from the transaction rather than failing it.
Many pactest tests that used to fail now return success codes, because
pacman now issues a prompt allowing the user to cancel rather than
failing many transactions, and the pactest scripts always choose to
cancel with no error rather than failing. The only net effect is that
the return status of pacman is now 0 in cases where it used to be

We don't need to create the directories when local or sync dbs are
registered. For example, if a sync db does not exist, we cannot even do
"pacman -Q" as an user.
Instead, we can create the local db if needed during the db_prepare
