TO INCONSISTENCY 

PROBLEM
--------
When we drop a partitoned table , we first gather the
information about partitions in the table from the 
table_name.par file and store it in an internal data 
structure.Then we delete this file and the data in 
the table. If the server crashes  after deleting the
file,then after recovering we cannot access the table
.Even we cannot drop the table ,because drop algorithm
requires par file to read the partition information.


FIX
---
1. We move the part of deleting par file after deleting 
   all the table data from the storage egine.
2. During drop operation if we detect that the par 
   file is missing then we delete the .frm file,since 
   there is no way of recovering without par file.
