locks all rows (BUG #3300). When using innobase_locks_unsafe_for_binlog
option InnoDB does not take locks for those rows which do not
belong to the result set or werent changed by the query. This fix removes
unnecessary locks also from SELECT and DELETE queries.
Fix bug #3478: InnoDB's FOREIGN KEY tables treated table and database names as case-insensitive; RENAME TABLE t to T would hang in an endless loop if t had a foreign key constraint defined on it

Fix bug #3478: InnoDB's FOREIGN KEY tables treated table and database names as case-insensitive; RENAME TABLE t to T would hang in an endless loop if t had a foreign key constraint defined on it; fix also a hang that would occur if one tried in ALTER TABLE or RENAME TABLE to create a foreign key constraint name that collided with another existing name
Link adaptive hash index entries to the buffer page, so that we can remove them quickly without knowing the record structure on that page; this was requested by Marko for the compact InnoDB table format; note that the adaptive hash index memory overhead grows by 67 %, maybe we have to tune this later somehow
Print more warnings to the .err log if ALTER TABLE ... IMPORT TABLESPACE fails for some reason
os0file.c:
Do not call exit(1) if os_file_delete() fails; remove unused parameter from
handle_error_no_exit()
fil0fil.c:
Allow DROP TABLE even if the .ibd file for the table does not exist
Add typecast from ulint to ssize_t in pread and pwrite, so that the type is according to the Linux man page; this will probably not help to fix the HP-UX 32-bit pwrite failure, since the compiler should do the appropriate typecasts anyway
Simple optimzations and cleanups
Removed compiler warnings and fixed portability issues
Added client functions 'mysql_embedded()' to allow client to check if we are using embedded server
Fixes for purify
If innodb_thread_concurrency would be exceeded, let a thread sleep 10 ms before entering the FIFO queue; previously, the value was 50 ms, which Peter Z considered too long
X-locks on duplicates also on LOAD DATA...REPLACE clause and
fixes a bug #6086 adding --disable_warnings and --enable_warnings around
the create table clauses in ctype_utf8 tests for InnoDB.
Fix bug #5960: if one updated a column so that its size changed, or updated it to an externally stored (TEXT or BLOB) value, then ANOTHER externally stored column would show up as 512 bytes of good data + 20 bytes of garbage in a consistent read that fetched the old version of the row
If one tries to drop an InnoDB table without an .ibd file, print to .err log that we DID remove the table from the internal data dictionary of InnoDB, and return DB_SUCCESS so that MySQL will delete the .frm file; the drawback in this is that then DROP TABLE returns success, and the user is not alerted; maybe it could return a warning
Fix bug #5137: if innodb_file_per_table was specified, CREATE TEMPORARY TABLE ... TYPE=InnoDB said that cannot find path specified, and made mysqld to exit(1)
