DISTINCT wasn't optimized away and caused creation of tmp table in wrong
case. This result in integer overrun and running out of memory.

Fix backported from 4.1. Now if optimizer founds that in result be only 1
row it removes distinct.

  1. it's wrong to use memcpy() for overlapped areas;
  2. we use it only once.
During merge to 4.1 will remove a memcpy_overlap() call 
from strings/ctype-tis620.c as well in order to fix 
bug #10836: ctype_tis620 test failure with ICC-compiled binaries on IA64.

When fixing Item_func_plus in ORDER BY clause field c is searched in all
opened tables, but because c is an alias it wasn't found there.

This patch adds a flag to select_lex which allows Item_field::fix_fields() 
to look up in select's item_list to find aliased fields.

   spec file (the $RBR variable did not get expanded, thus leaving old build
   roots behind)

Second platform fix for floating point rounding.

Reduced the precision of the test numbers.
Not all platforms could reproduce the exact numbers.

The problem was an ab-use of last_rkey_length.
Formerly we saved the packed key length (of the search key)
in this element. But in certain cases it got replaced by 
the (packed) result key length.
Now we use a new element of MI_INFO to save the packed key 
length of the search key.

  Delete: man/which.2

Ignored some generated files

Enlarged the counter variables to ulonglong.

Solution for 4.0 and 4.1.
If the caller cannot re-open table(s), it gives a NULL
'refresh' argument to open_table(). We used to ignore
flushes then. Now we ignore drops too.
