This changeset belongs to the fix of Bug#735 Prepared Statements: there is no support for Query Cache
  
- Create "--ps-protocol" and no "--<whatever>-protocol" variants of the former tests
  t/grant_cache.test and t/query_cache_sql_prepare.test.
- Some additional subtest and fixes of bugs
- Minor improvements 


mysql-test/include/grant_cache.inc:
  - Rename mysql-test/t/grant_cache.test to include/grant_cache.inc
  - Toplevel scripts running variants of this test are
       t/grant_cache_ps_prot.test (runs only with "--ps-protocol")
       t/grant_cache_no_prot.test (skipped if any protocol is assigned)
  - Modifications to include/grant_cache.inc:
    - Minor improvements like replace --error <number> by --error <name>
    - enable that some subtests are run with "--ps-protocol"
mysql-test/include/query_cache_sql_prepare.inc:
  - Rename t/query_cache_sql_prepare.test to include/query_cache_sql_prepare.inc
  - Toplevel scripts running variants of this test are
       query_cache_ps_ps_prot.test (skipped if other protocol than --ps-protocol is used.)
       query_cache_ps_no_prot.test (skipped if --<whatever>-protocol is used)   
  - Modifications to include/query_cache_sql_prepare.inc:
  - Minor improvements like add drop table
  - Add tests checking that 
    - another connection gets the same amount of QC hits
    - statements running via ps-protocol do not hit QC results of preceding sql EXECUTEs
mysql-test/r/grant_cache_no_prot.result:
  Updated result
mysql-test/r/query_cache_ps_no_prot.result:
  Updated result
tests/mysql_client_test.c:
  - correct wrong sized "for" loop
  - add some missing tests of query cache hit numbers
mysql-test/r/grant_cache_ps_prot.result:
  New BitKeeper file ``mysql-test/r/grant_cache_ps_prot.result''
mysql-test/r/query_cache_ps_ps_prot.result:
  New BitKeeper file ``mysql-test/r/query_cache_ps_ps_prot.result''
mysql-test/t/grant_cache_no_prot.test:
  Variant of the test grant_cache to be run without any "--<whatever>-protocol"
mysql-test/t/grant_cache_ps_prot.test:
  Variant of the test grant_cache to be run with "--ps-protocol" only
mysql-test/t/query_cache_ps_no_prot.test:
  Variant of the test query_cache_sql_prepare to be run without any "--<whatever>-protocol"
mysql-test/t/query_cache_ps_ps_prot.test:
  Variant of the test query_cache_sql_prepare to be run with "--ps-protocol" only

#
# Test grants with query cache
#
# Last update:
# 2007-05-03 ML - Move t/grant_cache.test to include/grant_cache.inc
# - Remove the disabling of the ps-protocol
# - minor improvements like error names instead of numbers
# - Create two toplevel tests sourcing this routine
#
# Running this test with and without "--ps-protocol" produces different
# Qcache_not_cached results because of the following reason:
# In normal protocol, a SELECT failing due to insufficient privileges
# increments Qcache_not_cached, while in ps-protocol, no.
# In detail:
# - In normal protocol,
# the "access denied" errors on SELECT are issued at (stack trace):
# mysql_parse/mysql_execute_command/execute_sqlcom_select/handle_select/
# mysql_select/JOIN::prepare/setup_wild/insert_fields/
# check_grant_all_columns/my_error/my_message_sql, which then calls
# push_warning/query_cache_abort: at this moment,
# query_cache_store_query() has been called, so query exists in cache,
# so thd->net.query_cache_query!=NULL, so query_cache_abort() removes
# the query from cache, which causes a query_cache.refused++ (thus,
# a Qcache_not_cached++).
# - In ps-protocol,
# the error is issued at prepare time;
# for this mysql_test_select() is called, not execute_sqlcom_select()
# (and that also leads to JOIN::prepare/etc). Thus, as
# query_cache_store_query() has not been called,
# thd->net.query_cache_query==NULL, so query_cache_abort() does nothing:
# Qcache_not_cached is not incremented.
#
# A run of this tests with sp/cursor/view protocol does not make sense
# because these protocols serve totally different purposes than this test.
