MXS-938: Recognize transaction start

Browse Source 
Now more information about a transaction start is provided. When
a transaction start statement is parsed, the type of the statement
with be QUERY_TYPE_BEGIN_TRX anded with QUERY_TYPE_READ or
QUERY_TYPE_WRITE if the transaction was explicitly started as READ
ONLY or READ WRITE.

Now also BEGIN WORK and [COMMIT|ROLLBACK] WORK are recognized.
"AND CHAIN" will still need to be recognized.
