queries to pass even when the node is not prepared to accept queries
(wsrep_ready=OFF). Added a test case.

Use host_or_ip instead of host as host may be 0
1. Do not use NULL `info' field in processlist to select the thread of
interest. This can fail if the read of processlist ends up happening after
REAP succeeds, but before the `info' field is reset. Instead, select on the
CONNECTION_ID(), making sure we still scan the whole list to trigger the same
code as in the original test case.
2. Wait for the query to really complete before reading it in the
processlist. When REAP returns, it only means that ack has been sent to
client, the reset of query stage happens a bit later in the code.

BUG#13627921 - MISSING FLAGS IN SQL_COMMAND_FLAGS MAY LEAD TO REPLICATION PROBLEMS
Flags in sql_command_flags[command] are not correctly set for the following
commands:
. SQLCOM_SET_OPTION is missing CF_CAN_GENERATE_ROW_EVENTS;
. SQLCOM_BINLOG_BASE64_EVENT is missing CF_CAN_GENERATE_ROW_EVENTS;
. SQLCOM_REVOKE_ALL is missing CF_CHANGES_DATA;
. SQLCOM_CREATE_FUNCTION is missing CF_AUTO_COMMIT_TRANS;
This may lead to a wrong sequence of events in the binary log. To fix
the problem, we correctly set the flags in sql_command_flags[command].
The reason for the failure was a bug in an include file on debian that causes 'struct stat'
to have different sized depending on the environment.
This patch fixes so that we always include my_global.h or my_config.h before we include any other files.
Other things:
- Removed #include <my_global.h> in some include files; Better to always do this at the top level to have as few
"always-include-this-file-first' files as possible.
- Removed usage of some include files that where already included by my_global.h or by other files.

CHECK.
Analysis:
----------
Issue here is, while creating or altering the InnoDB table,
if the foreign key defined on the table references a parent
table on which the user has no access privileges then the
table is created without reporting any error.
Currently the privilege level REFERENCES_ACL is unused
and is not used for access evaluation while creating the
table with a foreign key constraint or adding the foreign
key constraint to a table. But when no privileges are granted
to user then also access evaluation on parent table is ignored.
Fix:
---------
For DMLs, irrelevant of the fact, support does not want any
changes to avoid permission checks on every operation.
So, as a fix, added a function "check_fk_parent_table_access"
to check whether any of the SELECT_ACL, INSERT_ACL, UDPATE_ACL,
DELETE_ACL or REFERENCE_ACL privileges are granted for user
at table level. If none of them is granted then error is reported.
This function is called during the table creation and alter
operation.

The bug was that my_real_read() called net_before_header_psi() multiple times for long packets.
Fixed by adding a flag when we are reading a header.
Did also some cleanups to interface of my_net_read() to avoid unnecessary calls if performance schema is not used.
- Added my_net_read_packet() as a replacement for my_net_read(). my_net_read() is still in the client library for old clients.
- Removed THD->m_server_idle (not needed anymore as this is now given as argument to my_net_read_packet()
- Added my_net_read_packet(), which is a new version of my_net_read() with a new parameter if we are doing a read for a new command from the server.
- Added tests for compressed protocol and big packets

Bug#11756966 - 48958: STORED PROCEDURES CAN BE LEVERAGED TO BYPASS
DATABASE SECURITY
The problem was that CREATE PROCEDURE/FUCTION could be used to
check the existence of databases for which the user had no
privileges and therefore should not be allowed to see.
The reason was that existence of a given database was checked
before privileges. So trying to create a stored routine in
a non-existent database would give a different error than trying
to create a stored routine in a restricted database.
This patch fixes the problem by changing the order of the checks
for CREATE PROCEDURE/FUNCTION so that privileges are checked first.
This means that trying to create a stored routine in a
non-existent database and in a restricted database both will
give ER_DBACCESS_DENIED_ERROR error.
Test case added to grant.test.
