Update for autoconf 2.52

into mysql.sashanet.com:/reiser-data/mysql-4.0

fixed a couple of bugs with SEQ_READ_APPEND cache
rpl000016 still has non-deterministic result, but I am going to commit and
push since what I have is now better than what is in the main repository

Faster 'read_first_row' (Fixes slow 'preparing' state)
Read constant tables earlier, which provides better optimzations when using tables with <=1 row.
This also fixes a complicated bug involving const tables.

fixed too quick timeout in mysql-test-run which caused a race with the
 new server getting started before the old one completely finished 
 shutdown. This should fix the pid warning we've been getting as well as
 inconsistent results when running tests with the manager

  Added a comment for Tfr; Test for Tom

  Add nore info to make InnoDB installation easier

  Update mirror listing

before I can push

first pull, merge,test, and get it to work.

The main change is the new replication code - now we have two slave threads
SQL thread and I/O thread. I have also re-written a lot of the code to 
prepare for multi-master implementation. 

I also documented IO_CACHE quite extensively and to some extend, THD class.
