- Fix embedded build
- Backport disable of fallocate, it creates too short ibdata1
when used with O_DIRECT on old kernels
- Do not disable innodb during .deb install, we need it for
mysql.rpl_slave_state table.
Users can set different repplication filter rules for each replication connection, in my.cnf or command line.
But the rules set online will not record in master.info, it means if users restart MySQL, these rules will lose.
So if users wantn't their replication filter rules lose, they should write the rules in my.cnf.
Users can set rules by 2 ways:
1. Online SET command, "SET connection_name.replication_filter_settings = rules;".
2. In my.cnf, "connection_name.replication_filter_settings = rules".
If no connection_name in my.cnf, this rule will apply for ALL replication connection.
If no connetion_name in SET statement, this rull will apply for default_connection_name.
The official Debian Wheezy MySQL packages have versions like 5.5.30+dfsg-xxx.
Such version is larger than 5.5.30-yyy, so apt prefers it.
So use instead 5.5.30+maria-yyy, which is larger and can be pulled in
automatically by apt.
Also included are a couple of fixes for test failures in buildbot.
Merge of 10.0-mdev26 feature tree into 10.0-base.
Global transaction ID is prepended to each event group in the binlog.
Slave connect can request to start from GTID position instead of specifying
file name/offset of master binlog. This facilitates easy switch to a new
master.
Slave GTID state is stored in a table mysql.rpl_slave_state, which can be
InnoDB to get crash-safe slave state.
GTID includes a replication domain ID, allowing to keep track of distinct
positions for each of multiple masters.

Syntax modified to allow statements:
ALTER TABLE ADD/DROP COLUMN
ALTER TABLE ADD/DROP INDEX
ALTER TABLE ADD/DROP FOREIGN KEY
ALTER TABLE ADD/DROP PARTITION
ALTER TABLE CHANGE COLUMN
ALTER TABLE MODIFY COLUMN
DROP INDEX
to have IF (NOT) EXISTS options.
Appropriate implementations added to mysql_alter_table().

The patch contributed by Konstantin Osipov applied.
Native comments:
Implement multiple user-level locks per connection.
GET_LOCK() function in MySQL allows a connection to hold at most
one user level lock. Taking a new lock automatically releases the
old lock, if any.
The limit of one lock per session existed since early versions
of MySQL didn't have a deadlock detector for SQL locks.
MDL patches in MySQL 5.5 added a deadlock detector,
so starting from 5.5 it became possible to take multiple locks
in any order -- a deadlock, should it occur, would be detected
and an error returned to the client which closed the wait chain.
This is exactly what is done in this patch: ULLs are moved
to use MDL subsystem.
This fixes that by default LOAD DATA INFILE will not generate the error:
"Multi-statement transaction required more than 'max_binlog_cache_size' bytes of storage..."
mysql-test/suite/sys_vars/r/max_binlog_cache_size_basic.result:

sql/sys_vars.cc:
Increase default value of max_binlog_cache_size and max_binlog_stmt_cache_size to ulonglong_max.

that's default to number of CPUs
mysql-test/suite/archive/discover.test:
move_file uses rename(2), which may end up
with "Invalid cross-device link"
mysql-test/suite/archive/partition_archive.test:
on Solaris the error message is different
Change Item_func_get_system_var::val_xxx functions to use that.
mysql-test/t/variables.test:
@@GLOBAL.INIT_CONNECT is never NULL anymore. Nor it ever was.
It was a bug that empty string system variables appeared as NULL
in the *integer context* (but not in a string, real, or decimal context!)
