 There are currently a lot of operations that can't be done by a custom
 frontend without directly accessing the MYSQL database. This means that
 any custom frontend will need a dependency on mysql client libraries. It
 also means that the mysql server will need to be reconfigured to listen on
 the network interface.

 I propose that a SQL_QUERY command be added to the mythtv protocol that
 can execute SQL and receive results from the mythtv database.

 Example:
 {{{
 SELECT * FROM recordedseek WHERE chanid=1003 AND starttime='2008-11-17
 21:00:00' LIMIT 3;
 +--------+---------------------+------+--------+------+
 | chanid | starttime           | mark | offset | type |
 +--------+---------------------+------+--------+------+
 |   1003 | 2008-11-17 21:00:00 |    0 |    376 |    9 |
 |   1003 | 2008-11-17 21:00:00 |   12 | 356072 |    9 |
 |   1003 | 2008-11-17 21:00:00 |   24 | 708760 |    9 |
 +--------+---------------------+------+--------+------+
 }}}
 Frontend sends
 {{{
 SQL_QUERY[]:[]SELECT * FROM recordedseek WHERE chanid=1003 AND
 starttime='2008-11-17 21:00:00' LIMIT 3
 }}}
 Backend sends
 {{{
 3[]:[]1003[]:[]2008-11-17
 21:00:00[]:[]0[]:[]376[]:[]9[]:[]1003[]:[]2008-11-17
 21:00:00[]:[]12[]:[]356072[]:[]9[]:[]1003[]:[]2008-11-17
 21:00:00[]:[]24[]:[]708760[]:[]9
 }}}
 The first param is the number of rows, the subsequent params are the row
 data.

 For INSERT, UPDATE, DELETE, the result will only have one param and that
 is the number of rows affected.

 On error it sends
 {{{
 -1[]:[]Error message here
 }}}
