+ adopted signal to be as close as possible to 5.1...

Very complex select statements can create temporary tables
that are too big to be represented as a MyISAM table.

This was not checked at table creation time, but only at
open time. The result was an attempt to delete the 
"impossible" table.

But if the server is built --with-raid, MyISAM tries to 
open the table before deleting the files. It needs to find 
out if the table uses the raid support and how many raid 
chunks there are. This is done with an open "for repair",
which will almost always succeed.

But in this case we have an "impossible" table. The open
failed. Hence the files were not deleted. Also the error
message was a bit unspecific.

I turned an open error in this situation into the assumption 
of having no raid support on the table. Thus the normal data 
file is tried to be deleted. This may however leave existing 
raid chunks behind.

I also added a check in mi_create() to prevent the creation
of an "impossible" table. A more decriptive error message is
given in this case.

No test case. The required select statement is way too
large for the test suite. I added a test script to the
bug report.

- correction of previous patch

- make sure to allocate just enough pages in the fragments by using the actual
  row count from the backup, to avoid over allocation of pages to fragments, and
  thus avoid the bug

  An UNIQUE KEY consisting of NOT NULL columns
  was displayed as PRIMARY KEY in "DESC t1".
  According to the code, that was intentional
  behaviour for some reasons unknown to me.
  This code was written before bitkeeper time,
  so I cannot check who and why made this.
  After discussing on dev-public, a decision
  was made to remove this code

  Disable the simplistic auto dependency scan for test/bench (bug#20078)

This bug in Field_string::cmp resulted in a wrong comparison 
with keys in partial indexes over multi-byte character fields.
Given field a is declared as a varchar(16) collate utf8_unicode_ci
INDEX(a(4)) gives us an example of such an index.
  
Wrong key comparisons could lead to wrong result sets if 
the selected query execution plan used a range scan by 
a partial index over a utf8 character field.
This also caused wrong results in many other cases.

Using MAX()/MIN() on table with disabled indexes (by ALTER TABLE)
results in error 124 (wrong index) from storage engine.

The problem was that optimizer use disabled index to optimize
MAX()/MIN(). Normally it must skip disabled index and perform
table scan.

This patch skips disabled indexes for min/max optimization.

Fixes bug#17264, for alter table on win32 for successfull operation completion
it is used TL_WRITE(=10) lock instead of TL_WRITE_ALLOW_READ(=6), however here
in innodb handler TL_WRTIE is lifted to TL_WRITE_ALLOW_WRITE, which causes
race condition when several clients do alter table simultaneously.
