Nils Adermann dd527a4049 Remove weak rules
Since we no longer have suggest/recommend rules and no longer use any update
or feature rules so packages are removed by default, we do not need weak rules
anymore.

Nils Adermann bd66c27ff6 We mark packages as uninstallable by removing them from the repo
As it is faster to remove packages from the repos and keep them out of the
package pool to begin with, we don't need an installable() method on the
policy.

Everything is driven by jobs now.

Nils Adermann 64a451eaf9 Remove dontFix feature for local packages and explicit fix command
This made sense for the libzypp, so your kernel doesn't get deleted
just cause it thinks something is broken, but it doesn't really make
sense for composer.

Nils Adermann 1ee5d99405 When changing watched literals of a rule, update the parent's next pointer
The previous rule was not previously updated to point to the next rule when
removing a middle rule from the watch tree for a literal. This resulted in
jumping from one literal's watch tree to another's, which could then jump
back to the original and cause infinite loop in a case like #265.

Justin Rainbow 7eda0a8823 PHP 5.3.2 segmentation fault fix
For some reason, using the SqlFixedArray causes a Segmentation Fault during
an install or update.  Changing to a simple array fixes this issue, but in
turn uses more memory.  Which is why there is the version test.

Nils Adermann 61ad71b624 Reverse the transaction instruction order.
Early decisions cause later ones through dependencies. So in order to
perform the earlier decisions the later ones must be fulfilled first.

Nils Adermann bc672deb32 Moving rule iteration logic to a separate RuleSet and RuleSetIterator class 13 years ago
Nils Adermann 498125adbe Assertions are now properly decided before running the main solver.
Updating does not work yet. The test case works fine for installing/removing
the correct packages however. Weak (update/feature) rules are entirely ignored
so far.

Watches are on literal ids rather than literals to save on function calls
and memory usage. So a few methods for literals now have an id counter part.
This should probably be refactored to have the literal versions call the
id ones instead.
