update + test with latest release-candidates for AR 4.x
[mysql] initial hacks to allow running with non-official JDBC driver
allow running tests using `rake test_mysql DRIVER=MariaDB`
correct git ref matching in Gemfile
better jdbc- gem summaries + READMEs
[mysql] adapter.version (server version) that works with non-official driver(s) as well
[postgres] quote fix failure with ColumnDefinition on AR 4.0.6.rc2
do not assume MySQL official JDBC driver internals in test
hopefully there's no need to hack around rake (anymore)
allow to require jdbc/postgresql (maintain conventions) even as the gem name is f*cked
jdbc-mariadb gem initial setup (using MariaDB Java Client 1.1.7)
[mysql] updated so that we can run with non-official driver (+ against MariaDB)
+ includes preliminary `adapter: mariadb` support
- MariaDB driver does not return modified row count on execute - adapt those tests
fill-in History for 1.3.8
publicize constructors + allow access to ALLOCATORs for potential overriders
re-implement `jndi_config?` helper as a native method
re-implement connection factory setup in "native" Java code (back-compat)

- jndi: connection configuration now allow for username/password overrides
refactor jndi (derby) tests - we'll be likely adding some more
do not require eagerly driver.rb - likely won't be used
no need to eagerly load the type converter - not needed with most adapters
some more JNDI testing - now with MySQL as well
