Pushbuild fixes: 
 - Make MAX_SEL_ARGS smaller (even 16K records_in_range() calls is 
   more than it makes sense to do in typical cases)
 - Don't call sel_arg->test_use_count() if we've already allocated 
   more than MAX_SEL_ARGs elements. The test will succeed but will take
   too much time for the test suite (and not provide much value).

 - GRANT and REVOKE statments didn't have the "updating" flag set and
   thus statements with a table specified would not replicate if
   slave filtering rules where turned on.
   For example "GRANT ... ON test.t1 TO ..." would not replicate.

 - Post-review fixes

Thanks to Martin Friebe for finding and submitting a fix for this bug!

A table with maximum number of key segments and maximum length key name
would have a corrupted .frm file, due to an incorrect calculation of the
complete key length.  Now the key length is computed correctly (I hope) :-)

MyISAM would reject a table with the maximum number of keys and the maximum
number of key segments in all keys.  It would allow one less than this total
maximum.  Now MyISAM accepts a table defined with the maximum.  (This is a
very minor issue.)

- Added PARAM::alloced_sel_args where we count the # of SEL_ARGs
  created by SEL_ARG tree cloning operations.
- Made the range analyzer to shortcut and not do any more cloning 
  if we've already created MAX_SEL_ARGS SEL_ARG objects in cloning.
- Added comments about space complexity of SEL_ARG-graph 
  representation.

- Define Sql_alloc::operator new() as thow() so that C++ compiler
  handles NULL return values
(there is no testcase as there is no portable way to set limit on the 
amount of memory that a process can allocate)

  Don't use explicit calls to mysql-test-run in spec

            causes incorrect duplicate entries

Keys for BTREE indexes on ENUM and SET columns of MEMORY tables
with character set UTF8 were computed incorrectly. Many
different column values got the same key value.

Apart of possible performance problems, it made unique indexes
of this type unusable because it rejected many different
values as duplicates.

The problem was that multibyte character detection was tried
on the internal numeric column value. Many values were not
identified as characters. Their key value became blank filled.

Thanks to Alexander Barkov and Ramil Kalimullin for the patch,
which sets the character set of ENUM and SET key segments to
the pseudo binary character set.

 to 0 causes wrong (large) length to be read
 from the row in _mi_calc_blob_length() when 
 storing NULL values in (e.g) POINT columns.
 This large length is then used to allocate
 a block of memory that (on some OSes) causes
 trouble.
 Fixed by calling the base class's 
 Field_blob::reset() from Field_geom::reset()
 that is called when storing a NULL value into
 the column.
