Update AskMonty and Atlassian references to MariaDB

Fix spelling: occurred, execute, which etc

There was a race between end_slave() and cleanup code at the end of
handle_slave_sql(). This could cause access to master_info_index and
global_rpl_thread_pool after they had been freed.

Fix by skipping that cleanup if server shutdown is in progress, as is done
in other parts of the code as well (the cleanup, which stops worker threads
that are not needed anymore, is redundant anyway when the server is shutting
down).

MDEV-9643: Don't emit any "deb-systemd-helper not found" warnings

Index access becomes range every once in a while. Masked the value in addition
to other already masked columns

on FreeBSD 10 jemalloc is in libc, no separate libjemalloc is needed

this simplifies merging of MySQL and TokuDB

"#include <math.h>" has "#define isfinite(X) ..."
while "#include <cmath>" does "#undef isfinite"

in -std=c++11 mode <cmath> is included, we need a workaround
to provide a usable isfinite()

            configured withtout username

Federated/spider/connect engines or replication threads connecting to other host
with empty user name may crash mysqld.

This is addition to original patch, which adds a test case and amends a macro.

This reverts commit 13884cf2.

Fixed in 5.6 (merged in the next commit)

At least on Linux test fails because too small buffer pool.

Add check to avoid NULL-pointer access and added warning if share->ib_table
is not what expected.

MDEV-9469: 'Incorrect key file' on ALTER TABLE

InnoDB needs to rebuild table if column name is changed and
added index (or foreign key) is created based on this new
name in same alter table.

"x86_64" is "amd64" on FreeBSD

mysql.cc:
Unlike the main MYSQL structure, kill_mysql did not have MYSQL_OPT_PROTOCOL set.

Move all connection-related settings to a separate function and
use it both for the main MYSQL and for kill_mysql.

MDEV-9390 Function found_rows() gives incorrect result where the previous SELECT contains ORDER BY clause

use the raw found_rows value only when SQL_CALC_FOUND_ROWS was specified

following InnoDB's logic, altering a comment or a default
field's value needs "NO_LOCK", not EXCLUSIVE

Only set Alter_inplace_info::ALTER_COLUMN_VCOL flag if
a vcol might be affected by the ALTER TABLE statement

Followup fix for bug#35074: update the second location where
max_used_connections is calculated (to be like the
first one).
