Version for 5.0. Committed for merge.
If the result table is one of the select tables in INSERT SELECT,
we must not disable the result tables indexes before selecting.
Now the preparation is split into two prepare methods.
The first detects the situation and defers some preparations
until the second phase.

  BUG#6034 - Error code 124:  Wrong medium type.
  Added a new method for deferred preparation actions.
sql/sql_insert.cc:
  BUG#6034 - Error code 124:  Wrong medium type.
  If the insert table is one of the select tables, a part 
  of the result table preparations like disabling indexes
  has to be done after the select phase.
  This is now done in the new method select_insert::prepare2().
sql/sql_select.cc:
  BUG#6034 - Error code 124:  Wrong medium type.
  The result table preparation is now split into prepare() and
  prepare2(). Disabling indexes and other preparation stuff
  is deferred until after the selection phase.

macros.

It does not fixes any bugs in 4.0. But it prevents from future error in
any bugfixes that may use these macros. Also after merging into 4.1 tree
this cleanup will fix bug #7884 "Able to add invalid unique index on
TIMESTAMP prefix".


sql/field.h:
  Since FIELDFLAG_INTERVAL, FIELDFLAG_BITFIELD, FIELDFLAG_BLOB and
  FIELDFLAG_GEOM flags occupy the same space as number of decimals for
  FIELDFLAG_NUMBER fields, it is safer to check in "f_is_geom()"-type
  macros that we have non-number field, like we already do in f_is_blob()
  macro.

not default_charset_into. It fixes the
problem that in some cases numbers where
treated as CHAR(N), not as BINARY(N), e.g.
wrong 'charsetnr' when sent to the client side.
2. IFNULL didn't aggregate argument charsets
and collations, so IFNULL(1,'a') produced
a CHAR(N). Now produces a BINARY(N).
3. SELECT PROCEDURE ANALIZE now returns
BINARY columns, which is much better than it worked
previously: CHAR with the default character set.
But in the future it's worth to fix the fields
'Field_name' and 'Optimal_fieldtype' to use UTF8,
and 'Min_value' and 'Max_value' to inherit their charsets
from the original items. But it is not important,
and BINARY(N) is OK for now.
4. Tests were fixed accordingly. No new tests were
made, as the old onces cover everything.
