innodb_force_recovery is set. Fill in bogus data for those indexes

This patch doesn't get rid of the need to acquire the dict_sys->mutex but
reduces the need to keep the mutex locked for the duration of the query
to fsp_get_available_space_in_free_extents() from ha_innobase::info().

The callers should indicate that the dictionary is locked or not using
the trx->dict_operation_lock_mode == RW_X_LATCH mode. Checking explicitly
for system tables is unnecessary.

Fix a debug assertion that was missed in svnrev:2380 (fix for Bug# 35352).

Approved by Marko on IRC

Remove a bogus debug assertion that triggered the bug.
Add assertions precisely where records must not be delete-marked.
And a comment to clarify when the record is allowed to be delete-marked.

  Currently we do a full validation of AHI whenever check tables is

Problem: The original patch didn't compile on debug_werror
due to wrong format in printf("%d") for size_t variables.

Fix: Adding cast to (int).

/*![:version:] Query Code */, where [:version:] is a sequence of 5 
digits representing the mysql server version(e.g /*!50200 ... */),
is a special comment that the query in it can be executed on those 
servers whose versions are larger than the version appearing in the 
comment. It leads to a security issue when slave's version is larger 
than master's. A malicious user can improve his privileges on slaves. 
Because slave SQL thread is running with SUPER privileges, so it can
execute queries that he/she does not have privileges on master.

This bug is fixed with the logic below: 
- To replace '!' with ' ' in the magic comments which are not applied on
  master. So they become common comments and will not be applied on slave.

- Example:
  'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /*!99999 ,(3)*/
  will be binlogged as
  'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /* 99999 ,(3)*/

mysql-test/suite/rpl/t/rpl_conditional_comments.test:
  Test the patch for this bug.
sql/mysql_priv.h:
  Rename inBuf as rawBuf and remove the const limitation.

  To replace '!' with ' ' in the magic comments which are not applied on
  master.
sql/sql_lex.h:
  Remove the const limitation on parameter buff, as it can be modified in the function since

  Add member function yyUnput for Lex_input_stream. It set a character back the query buff.

  Remove the const limitation on parameter part_buff, as it can be modified in the function since

to mysql-5.1-innodb plugin.

Do not attempt to test the innodb plugin with the embedded server,
it's not supported for now.

Problem: The functions my_like_range_xxx() returned
badly formed maximum strings for Asian character sets,
which made problems for storage engines.

Fix: 
- Removed a number my_like_range_xxx() implementations,
  which were in fact dumplicate code pieces.
- Using generic my_like_range_mb() instead.
- Setting max_sort_char member properly for Asian character sets
- Adding unittest/strings/strings-t.c, 
  to test that my_like_range_xxx() return well-formed 
  min and max strings.

Notes:

- No additional tests in mysql/t/ available.
  Old tests cover the affected code well enough.

InnoDB Plugin 1.0.10 has been released with MySQL 5.1.49.

Bug#49542 - Do as the comment suggests and downgrade directory errors from find_file() to a warning unless they happen during a SHOW command.
