Lukas Fleischer b44411fb53 Use gitnamespaces for efficient storage
Instead of using one Git repository per package, use a single large
object storage for space efficiency. The refs of the individual package
bases are divided using gitnamespaces(7) which allows for exposing each
namespace as an independent repository easily. Also, git-serve is
modified to create a branch for each package, allowing to browse the
large repository with cgit.

3. Reset the packager field of all package bases:
----
UPDATE PackageBases SET PackagerUID = NULL;
----
4. Create a new table for package base co-maintainers:
----
CREATE TABLE PackageComaintainers (
UsersID INTEGER UNSIGNED NOT NULL,
PackageBaseID INTEGER UNSIGNED NOT NULL,
Priority INTEGER UNSIGNED NOT NULL,
INDEX (UsersID),
INDEX (PackageBaseID),
FOREIGN KEY (UsersID) REFERENCES Users(ID) ON DELETE CASCADE,
FOREIGN KEY (PackageBaseID) REFERENCES PackageBases(ID) ON DELETE CASCADE
