The "mysql client in mysqld"(which is used by
replication and federated) should use alarms instead of setting
socket timeout value if the rest of the server uses alarm. By
always calling 'my_net_set_write_timeout'
or 'net_set_read_timeout' when changing the timeout value(s), the
selection whether to use alarms or timeouts will be handled by
ifdef's in those two functions.

This is minimal backport of patch for BUG#26664, which was pushed
to 5.0 and up.

Affects 4.1 only.


include/mysql_com.h:
  Move the net_set_*_timeout function declarations to mysql_com.h
sql-common/client.c:
   Use my_net_read_timeout or my_net_write_timeout when setting the timeouts
sql/mysql_priv.h:
  Move the net_set_*_timeout function declarations to mysql_com.h
