Add function 'mtr_rmtree' it will try 'rmtree' and if that fails (most likely
due to permission problems we will fun File::find to chmod all files and dirs
to 0777 and then delete.

This is a performance bug, affecting in particular the bison generated code
for the parser.
Prior to this fix, the grammar used a long chain of reduces to parse an
expression, like:
bit_expr -> bit_term
bit_term -> bit_factor
bit_factor -> value_expr
value_expr -> term
term -> factor
etc
This chain of reduces cause the internal state automaton in the generated
parser to execute more state transitions and more reduces, so that the
generated MySQLParse() function would spend a lot of time looping to execute
all the grammar reductions.
With this patch, the grammar has been reorganized so that rules are more
"flat", limiting the depth of reduces needed to parse <expr>.
Tests have been written to enforce that relative priorities and properties
of operators have not changed while changing the grammar.
See the bug report for performance data.

Currently the Last_query_cost session status variable shows
only the cost of a single flat subselect. For complex queries
(with subselects or unions etc) Last_query_cost is not valid
as it was showing the cost for the last optimized subselect.
Fixed by reseting to zero Last_query_cost when the complete
cost of the query cannot be determined.
Last_query_cost will be non-zero only for single flat queries.

Fix typo, "next_con" -> "con"
client/mysqltest.c:
Reuse "find_connection_by_name" both from "do_close_connection" and "do_send_quit"
Adjust alignment of comment
Fix typo in "do_close_connection", it used the global variable "next_con" instead
of local variable "con"
to perform this analyzis)
client/mysqltest.c:
Add function 'show_query' and use it to output some debug queries when
"sync_with_master" has failed.
mysql-test/mysql-test-run.pl:
Move "analyze_testcase_failure" to mysqltest
- Merge sslaccept and sslconnect.
- Atomically "reset" vio to VIO_TYPE_SSL when the SSL connection has
succeeded, this avoids having to revert anything and thus protects
against "close_active_vio" in the middle.
- Add some variance to the testcase
mysql-test/t/rpl_ssl.test:
Add some variance by running two selects before stopping the slave
Check that number of records in t1 are equal on master and slave
vio/viossl.c:
Rewrite sslconnect and sslaccept to automically "reset" the vio
to VIO_TYPE_SSL. Also use the fd from 'SSL_get_fd' to avoid
setting vio->sd to -1, that previously occured when "close_active_vio"
was called during connect/accept.
Merge the two function since they were exactly the same except for one line.
Update the DBUG printouts to be generic(i.e use peer instead of client/server).
The optimization that uses a unique index to remove GROUP BY, did not
ensure that the index was actually used, thus violating the ORDER BY
that is impled by GROUP BY.
Fixed by replacing GROUP BY with ORDER BY if the GROUP BY clause contains
a unique index. In case GROUP BY ... ORDER BY null is used, GROUP BY is
simply removed.

filesort also, in which case we can no longer gurantee correct ordering.

If, after the tables are locked, one of the conditions to read from a
HANDLER table is not met, the handler code wrongly jumps to a error path
that won't unlock the tables.
The user-visible effect is that after a error in a handler read command,
all subsequent handler operations on the same table will hang.
The fix is simply to correct the code to jump to the (same) error path that
unlocks the tables.
mysql-test/r/handler.result:
Bug#30632 test case result
mysql-test/t/handler.test:
Bug#30632 test case
sql/sql_handler.cc:
Always unlock the internal and external table level locks if any of the conditions
(including errors) to read from a HANDLER table are not met.
The problem from a user's perspective: user creates table A, and then tries
to CREATE TABLE a SELECT from A - and this causes a deadlock error, a hang,
or fails with a debug assert, but only if the storage engine is InnoDB.
The origin of the problem: InnoDB uses case-insensitive collation
(system_charset_info) when looking up the internal table share, thus returning
the same share for 'a' and 'A'.
Cause of the user-visible behavior: since the same share is returned to SQL
locking subsystem, it assumes that the same table is first locked (within the
same session) for WRITE, and then for READ, and returns a deadlock error.
However, the code is wrong in not properly cleaning up upon an error, leaving
external locks in place, which leads to assertion failures and hangs.
Fix that has been implemented: the SQL layer should properly propagate the
deadlock error, cleaning up and freeing all resources.
Further work towards a more complete solution: InnoDB should not use case
insensitive collation for table share hash if table names on disk honor the case.

locking subsystem detects a deadlock error.
- "mysql" and "mysqlcheck" should not read defaults file
client/mysql_upgrade.c:
Instruct "mysql" and "mysqlcheck" that is invoked by "mysql_upgrade" not
to read defaults file, they should get all the parameters they need from
mysql_upgrade(that read the default file)
- Chop off .libs/ part of path if running in non installed builddir
using libtool
client/mysql_upgrade.c:
Chop off .libs part of path to avoid executing "non relinked" binaries
that would use the system installed dynamic libraries instead of the
newly built ones.
1) Ensure "init_db.sql" and "test_db-sql" really get built.
2) Ensure the "*.def" files with NetWare linker options get distributed to the proper directories.
netware/BUILD/compile-netware-END:
Ensure the "*.def" files are built for NetWare.
This is a backport of a 5.1 fix which may not be needed in 5.0 but cannot do any harm:
the general "link_sources" step might fall victim to a cleanup which would be fatal
just for NetWare, because of problems in the ordering of SUBDIR entries.
netware/Makefile.am:
1) The scripts "init_db.sql" and "test_db.sql" must be built in the NetWare phase.
2) Use "basename", not sed.
- Move increment of "i" to "increment section" of for loop
- Protect against writing after end of "buff"(backport from 5.1)
sql/sql_show.cc:
- Move the increment of i to "increment" section of for loop. Since "i"
was initially 0 the for loop exited immediately
- Add protection for writing after end of "buff"
