This patch collects all previous patches into one.
The main problem was due to that there is are two variables -
dflt_key_cache and sql_key_cache with have more or less duplicate
function. The reson for the bug was that the default value in the key
cache hash was set to dflt_key_cache, then sql_key_cache was set to a
new key cache object, and then dflt_key_cache was set to sql_key_cache
which was different from the dflt_key_cache_var. After sending SIGHUP,
the server was using the original default value for the key cache hash,
which was different from the actual key cache object used for the
default key cache.
of concurrent connections for the same account)"
Added support of account specific max_user_connections limit. Made all
user limits to be counted per account instead of the old behavior,
which was per user/host accounting. Added option which enables the old
behavior. Added testing of these to the test suite.
(After review version).

tables requires privileges for them if some table or column level grants
present" (with after-review fixes).
We should set SELECT_ACL for implicitly opened tables in
my_tz_check_n_skip_implicit_tables() to be able to bypass privilege
checking in check_grant(). Also we should exclude those tables from
privilege checking in multi-update.
Added auto-correct of field length for enum/set tables for ALTER TABLE
This is becasue of a bug in previous MySQL 4.1 versions where the length for enum/set was set incorrectly after ALTER TABLE
results." a.k.a. "Proper cleanup of subqueries is missing for SET and DO
statements". (Version #2 with after-review fixes).
To perform proper cleanup for statements that can contain subqueries
but don't have main select we must call free_undelaid_joins().
- ndb_use_exact_count
- ndb_autoincrement_prefetch_sz
- ndb_use_transactions
- ndb_force_send
moved "inlined" functions to .cc file since they are virtual anyways
enabled printout od ndb errors in warnings even if mapping existst to mysql error code
