Log command to the general log table

Log given command to the general log table.

Parameters:

event_time	command start timestamp
user_host	the pointer to the string with user info
user_host_len	length of the user_host string. this is computed once and passed to all general log event handlers
thread_id	Id of the thread, issued a query
command_type	the type of the command being logged
command_type_len	the length of the string above
sql_text	the very text of the query being executed
sql_text_len	the length of sql_text string

Returns:

This function attempts to never call my_error(). This is necessary, because general logging happens already after a statement status has been sent to the client, so the client can not see the error anyway. Besides, the error is not related to the statement being executed and is internal, and thus should be handled internally (

Todo:

: how?). If a write to the table has failed, the function attempts to write to a short error message to the file. The failure is also indicated in the return value.

Return values:

FALSE	OK
TRUE	error occured

Implements Log_event_handler.
