real_sleep use the value from opt_sleep as number of seconds to sleep

DESCRIPTION
sleep <seconds>

The difference between the sleep and real_sleep commands is that sleep
uses the delay from the --sleep command-line option if there is one.
(If the --sleep option is not given, the sleep command uses the delay
specified by its argument.) The real_sleep command always uses the
delay specified by its argument. The logic is that sometimes delays are
cpu-dependent, and --sleep can be used to set this delay. real_sleep is
used for cpu-independent delays.

NOTE
Sometimes in a test the client starts before
the server - to solve the problem, we try again
after some sleep if connection fails the first
time
This function will try to connect to the given server
"opt_max_connect_retries" times and sleep "connection_retry_sleep"
seconds between attempts before finally giving up.
This helps in situation when the client starts
before the server (which happens sometimes).
It will only ignore connection errors during these retries.

Read one "line" from the file
SYNOPSIS
read_line
buf buffer for the read line
size size of the buffer i.e max size to read
DESCRIPTION
This function actually reads several lines and adds them to the
buffer buf. It continues to read until it finds what it believes
is a complete query.
Normally that means it will read lines until it reaches the
"delimiter" that marks end of query. Default delimiter is ';'
The function should be smart enough not to detect delimiter's
found inside strings surrounded with '"' and '\'' escaped strings.
If the first line in a query starts with '#' or '-' this line is treated
as a comment. A comment is always terminated when end of line '\n' is
reached.

--timer-file=<filename> is given. The timer result is written
to that file when the result is available. To not confuse
mysql-test-run with an old obsolete result, we remove the file
before executing any commands. The time we measure is
- If no explicit 'start_timer' or 'end_timer' is given in the
test case, the timer measure how long we execute in mysqltest.
- If only 'start_timer' is given we measure how long we execute
from that point until we terminate mysqltest.
- If only 'end_timer' is given we measure how long we execute
from that we enter mysqltest to the 'end_timer' is command is
executed.
- If both 'start_timer' and 'end_timer' are given we measure
the time between executing the two commands.
