Split UPGRADING

Split the upgrade instructions into several files, one file per version
in order to keep them small, readable and to avoid merge conflicts.

+1. Drop foreign keys from the "Sessions" table:
+
+`ALTER TABLE Sessions DROP FOREIGN KEY Sessions_ibfk_1;` should work in most
+cases. Otherwise, check the output of `SHOW CREATE TABLE Sessions;` and use the
+foreign key name shown there.
+
+2. Run the following MySQL statements:
+
+----
+ALTER TABLE Sessions
+	ADD FOREIGN KEY (UsersID) REFERENCES Users(ID) ON DELETE CASCADE;
+ALTER TABLE PackageDepends
+	ADD FOREIGN KEY (PackageID) REFERENCES Packages(ID) ON DELETE CASCADE,
+	ADD FOREIGN KEY (DepPkgID) REFERENCES Packages(ID) ON DELETE CASCADE;
+ALTER TABLE PackageSources
+	ADD FOREIGN KEY (PackageID) REFERENCES Packages(ID) ON DELETE CASCADE;
+ALTER TABLE TU_VoteInfo
+	ADD FOREIGN KEY (SubmitterID) REFERENCES Users(ID) ON DELETE CASCADE;
+ALTER TABLE TU_Votes
+	ADD FOREIGN KEY (VoteID) REFERENCES TU_VoteInfo(ID) ON DELETE CASCADE,
+	ADD FOREIGN KEY (UserID) REFERENCES Users(ID) ON DELETE CASCADE;
+ALTER TABLE PackageComments
+	MODIFY DelUsersID INTEGER UNSIGNED NULL DEFAULT NULL;
+UPDATE PackageComments SET DelUsersID = NULL WHERE DelUsersID = 0;
+ALTER TABLE Packages
+	MODIFY SubmitterUID INTEGER UNSIGNED NULL DEFAULT NULL,
+	MODIFY MaintainerUID INTEGER UNSIGNED NULL DEFAULT NULL;
+UPDATE Packages SET SubmitterUID = NULL WHERE SubmitterUID = 0;
+UPDATE Packages SET MaintainerUID = NULL WHERE MaintainerUID = 0;
+----
+
+3. (optional) If you converted your database from MyISAM to InnoDB during the
+upgrade process from 1.7.0 to 1.8.0 or from 1.8.0 to 1.8.1 without completely
+rebuilding the database from the MySQL schema, you should additionally run the
+following MySQL statements to add missing foreign keys:
+
+----
+ALTER TABLE Users
+	ADD FOREIGN KEY (AccountTypeID) REFERENCES AccountTypes(ID) ON DELETE NO ACTION;
+ALTER TABLE Packages
+	ADD FOREIGN KEY (CategoryID) REFERENCES PackageCategories(ID) ON DELETE NO ACTION,
+	ADD FOREIGN KEY (SubmitterUID) REFERENCES Users(ID) ON DELETE NO ACTION,
+	ADD FOREIGN KEY (MaintainerUID) REFERENCES Users(ID) ON DELETE NO ACTION;
+ALTER TABLE PackageVotes
+	ADD FOREIGN KEY (UsersID) REFERENCES Users(ID) ON DELETE CASCADE,
+	ADD FOREIGN KEY (PackageID) REFERENCES Packages(ID) ON DELETE CASCADE;
+ALTER TABLE PackageComments
+	ADD FOREIGN KEY (UsersID) REFERENCES Users(ID) ON DELETE CASCADE,
+	ADD FOREIGN KEY (DelUsersID) REFERENCES Users(ID) ON DELETE CASCADE,
+	ADD FOREIGN KEY (PackageID) REFERENCES Packages(ID) ON DELETE CASCADE;
+ALTER TABLE CommentNotify
+	ADD FOREIGN KEY (PkgID) REFERENCES Packages(ID) ON DELETE CASCADE,
+	ADD FOREIGN KEY (UserID) REFERENCES Users(ID) ON DELETE CASCADE;
