/*
Find a handler for the given errno.
This is called from all error message functions (e.g. push_warning,
net_send_error, et al) when a sp_rcontext is in effect. If a handler
is found, no error is sent, and the the SP execution loop will instead
invoke the found handler.
This might be called several times before we get back to the execution
loop, so m_hfound can be >= 0 if a handler has already been found.
(In which case we don't search again - the first found handler will
be used.)
Handlers are pushed on the stack m_handler, with the latest/innermost
one on the top; we then search for matching handlers from the top and
down.
We search through all the handlers, looking for the most specific one
(sql_errno more specific than sqlstate more specific than the rest).
Note that mysql error code handlers is a MySQL extension, not part of
the standard.
SYNOPSIS
sql_errno The error code
level Warning level
RETURN
1 if a handler was found, m_hfound is set to its index (>= 0)
