Depending on the queries we use different data processing methods
and can lose some data in case of double (and decimal in 4.1) fields.

The fix consists of two parts:
1. double comparison changed, now double a is equal to double b 
if (a-b) is less than 5*0.1^(1 + max(a->decimals, b->decimals)). 
For example, if a->decimals==1, b->decimals==2, a==b if (a-b)<0.005
2. if we use a temporary table, store double values there as is 
to avoid any data conversion (rounding).

Added a test case for bug #6774 "Replication fails with Wrong usage of DB GRANT and GLOBAL PRIVILEGES"

and combined, they add a platform-specific warning.  The warnings 
are not the goal of the test, in any case.

 - Additional patch removing check for mysql_errno on already closed
   mysql1

files. This helps stability of multiple parallel automated test runs,
avoiding the situation where one bad build fills up disk with 1000s of
core files, causing failures in other test runs.
