@brief Bison callback to report a syntax/OOM error
This function is invoked by the bison-generated parser
when a syntax error, a parse error or an out-of-memory
condition occurs. This function is not invoked when the
parser is requested to abort by semantic action code
by means of YYABORT or YYACCEPT macros. This is why these
macros should not be used (use MYSQL_YYABORT/MYSQL_YYACCEPT
instead).
The parser will abort immediately after invoking this callback.
This function is not for use in semantic actions and is internal to
the parser, as it performs some pre-return cleanup.
In semantic actions, please use my_syntax_error or my_error to
push an error into the error stack and MYSQL_YYABORT
to abort from the parser.

This part of the parser is about handling of the partition information.
It's first version was written by Mikael Ronström with lots of answers to
questions provided by Antony Curtis.
The partition grammar can be called from three places.
1) CREATE TABLE ... PARTITION ..
2) ALTER TABLE table_name PARTITION ...
3) PARTITION ...
The first place is called when a new table is created from a MySQL client.
The second place is called when a table is altered with the ALTER TABLE
command from a MySQL client.
The third place is called when opening an frm file and finding partition
info in the .frm file. It is necessary to avoid allowing PARTITION to be
an allowed entry point for SQL client queries. This is arranged by setting
some state variables before arriving here.
To be able to handle errors we will only set error code in this code
and handle the error condition in the function calling the parser. This
is necessary to ensure we can also handle errors when calling the parser
from the openfrm function.

Class should rather have a constructor which takes arguments,

This rule accepts just about anything. The reason is that we have
empty-producing rules in the beginning of rules, in this case
subselect_start. This forces bison to take a decision which rules to
reduce by long before it has seen any tokens. This approach ties us
to a very limited class of parseable languages, and unfortunately
SQL is not one of them. The chosen 'solution' was this rule, which
produces just about anything, even complete bogus statements, for
instance ( table UNION SELECT 1 ).
Fortunately, we know that the semantic value returned by
select_derived->value is NULL if it contained a derived table, and a pointer to
the base table's TABLE_LIST if it was a base table. So in the rule
regarding union's, we throw a parse error manually and pretend it
was bison that did it.
Also worth noting is that this rule concerns query expressions in
the from clause only. Top level select statements and other types of
subqueries have their own union rules.

This warning will be printed when

Printing the warning for [2] is intentional, to cover the
following scenario:
- A user define a SF 'foo' using MySQL 5.N
- An application uses select foo(), and works.
- MySQL 5.{N+1} defines a new native function 'foo', as
part of a new feature.
- MySQL 5.{N+1} documentation is updated, and should mention
that there is a potential incompatible change in case of
existing stored function named 'foo'.
- The user deploys 5.{N+1}. At this point, 'select foo()'
means something different, and the user code is most likely
broken (it's only safe if the code is 'select db.foo()').
With a warning printed when the SF is loaded (which has to occur
before the call), the warning will provide a hint explaining
the root cause of a later failure of 'select foo()'.
With no warning printed, the user code will fail with no
apparent reason.
Printing a warning each time db_load_routine is executed for
an ambiguous function is annoying, since that can happen a lot,
but in practice should not happen unless there *are* name
collisions.
If a collision exists, it should not be silenced but fixed.
