Migrate all DB code to use PDO

All DB code currently uses the quickly aging mysql_* functions. These
functions are strongly discouraged and may eventually be deprecated.

Transition all code to utilize the PDO data access abstraction layer. PDO
allows for consistent query code across multiple databases. This could
potentially allow for someone to use a database other than MySQL with
minimal code changes.

All functions and behaviors are reproduced as faithfully as possible with
PDO equivalents and some changes in code.
