util.array: Fix new() library function Backport of ffe4adbd2af9 since new was added in the 0.12 branch

mod_tokenauth: Fix revoking a single token without revoking whole grant This appears to have been a copy-paste of the grant revocation function, or maybe the other way around. Either way, it deleted the whole grant instead of the individual token as might be expected.

util.array: Fix new() library function

tests: Add hack to test only a single storage driver Fixes that LuaDBI being unavailable makes these produce nothing but endless stack overflows in luarocks.

tests: Update storagemanager tests for prosody.* namespace change Part of an attempt to make these tests work again. Previously they would just explode in a million luarocks stack overflows

mod_storage_sql: Spell out missing dependencies Using util.dependencies appeared to cause problems with running tests in Busted, so this also removes that and uses pcall directly.

mod_storage_sql: Pass variables as arguments instead of upvalues Probably a workaround for the lack of argument passing when using xpcall in Lua 5.1, no longer relevant.

util.sql: Remove unused String() and Integer() functions According to MattJ, leftovers from an earlier vision for util.sql

util.sqlite3: Clean up unused variables Many leftovers from the earlier version of util.sql this was based on and cleanup applied there since then.

util.datamanager: Always reset index after list shift Shifting the index does not work reliably yet, better to rebuild it from scratch. Since there is minimal parsing involved in that, it should be more efficient anyway.
