"MySQL server does not detect if garbage chara at the end of query"
Allow the parser to see the garbage characters.
Garbage should cause the parser to report an error.
sql/sql_lex.cc:
Return END_OF_INPUT when at the end of the input buffer.
Allows the parser to determine if there is junk after a \0 character.

"MySQL server does not detect if garbage chars at the end of query":
Detect garbage chars at the end of the query or at the end of a query
for a prepared statement (which happens if mysql_real_query() or mysql_prepare()
were called with a too big 'length' parameter (bigger than the real intended
length of the query: then we receive a query + garbage characters from the
client). This resulted in garbage chars written into the binlog.
Now instead the client receives something like:
'You have an error in your SQL syntax. Check the manual that corresponds
to your MySQL server version for the right syntax to use near '!stmt'
at line 1' i.e. the server is pointing at the weird tail of the query
(this '!stmt' are the garbage chars sent by the client).
All tests pass, except mysqldump.test and ctype_utf8.test but they failed
before the patch.
sql/sql_parse.cc:
Detect garbage chars at the end of the query
(which happens if mysql_real_query() was called with a too big 'length'
parameter (bigger than the real intended length of the query: then
we receive a query + garbage characters from the client).
sql/sql_prepare.cc:
Detect garbage chars at the end of the query
(which happens if mysql_prepare() was called with a too big 'length'
parameter (bigger than the real intended length of the query: then
we receive a query + garbage characters from the client).
tests/client_test.c:
The change to sql_parse.cc and sql_prepare.cc rightfully gives many
syntax errors to tests/client_test.c which is full of
mysql_prepare(mysql, "SHOW TABLES", 100).
Correcting all these commands.

added setting of 'neg' in Item_param::set_time() (looks like the only forgotten
member).
It's the second place I find where 'neg' was forgotten.
The symptom was unexpected negative times in the binary log when running
tests/client_test.c (test_date() in fact):
# at 43009
#040210 15:46:42 server id 1 log_pos 43009 Query thread_id=1 exec_time=0 error_code=0
SET TIMESTAMP=1076424402;
INSERT INTO test_date VALUES('2000-01-10 11:16:20','-11:16:20' etc
sql/item.cc:
Don't forget to copy 'neg'.

Don't show PSEUDO_THREAD_ID in SHOW VARIABLES because:
- we don't want people to discover this variable as it could never do good to
set it (it was designed for use by mysqlbinlog only, so that a thread can have
several temp tables of the same name at the same time)
- if we show it in SHOW VARIABLES, Mysql Administrator will display it and
this will force us to put a description, so all MySQL Administrator user
will be aware of this variable, some may have the idea to set it with a SET
command, and then it will cause bad things.
The variable is still settable, and still visible with SELECT @@.
