• Remove flawed execute("ROLLBACK") approach; #reset! defaults to nothing

  Will need community help to fill out what #reset! should do for each adapter

• Fix failure to retain value of allow_concurrency

  - Also carry allow_concurrency value through to connection adapter
  (for postgresql)

• Add synchronization to connection pool also

• Introduce synchronization around connection pool access

  - use new active support Module#synchronize
  - allow_concurrency now switches between a null monitor and a
  regular monitor (defaulting to null monitor to avoid overhead)

• Module#synchronize: Add testcase to ensure that singleton methods can be wrapped

• Add method punctuation handling to #synchronize

• Adds Module#synchronize for easier method-level synchronization.

• Rename defined_connections to connection_pools

  - Distinguis meaning of "active_connections" to always mean connections
  associated with the current thread

• Initial conversion to connection pool

  So far so good, tests still run clean. Next steps: synchronize connection pool access
  and modification, and change allow_concurrency to simply switch a real lock for a
  null lock.

• Change all databases.rake adapter 'when' statements to use regexes.

  This is more friendly to JRuby/JDBC adapters (with names like 'jdbcmysql')
  and leaves the door open to alternate implementations of adapters in the
  future.
