1756d087cd Fix for BUG#59894 
"set optimizer_switch to e or d causes invalid memory writes/valgrind warnings":
due to prefix support, the argument "e" was overwritten with its full value
"engine_condition_pushdown", which caused a buffer overrun.
This was wrong usage of find_type(); other wrong usages are fixed here too.
Please start reading with the comment of typelib.c.

client/mysqldump.c:
  A bug: find_type() expects a bitmap as 3rd argument
  (each bit is a flag controlling a behaviour of the function);
  here it was instead passed the length of the string to search!
  That could give random behaviour of find_type()
  depending on the string.
  We rather need to pass a correct flag to find_type().
  The correct flag is FIND_TYPE_BASIC (0).
  Flag 8 is not needed as buff cannot have a comma (see how buff is filled).
  Flag 1 looks like a superfluous restriction.
  Flag 4 is not user-friendly (why use
  --compatible=2 rather than --compatible=mysql40 ?, and
  we probably not commit to "2" always meaning "mysql40"
  until the end of times).
include/mysql.h.pp:
  This isn't a problematic API change as we go from char* to const char*:
  existing code will run unchanged.
include/typelib.h:
  named constants. Not an enum to not significantly change
  the declaration of find_type() which would be an API change
  (typelib.h is included in mysql.h).
mysql-test/r/mysqldump.result:
  correct result (see the two requested modes in SQL_MODE)
mysql-test/suite/sys_vars/t/optimizer_switch_basic.test:
  test for BUG#59894. The second SET used to crash.
mysql-test/t/mysqldump.test:
  we had no test for multiple modes in --compatible, which is
  supported according to --help
mysys/typelib.c:
  Fix for BUG#59894. parse_name() is asked to match "e" with a row
  of the TYPELIB (the TYPELIB lists permitted flags of optimizer_switch;
  and comes from optimizer_switch_names[] of sys_vars.cc).
  find_type() is capable of supporting prefixes, but if it is not
  passed flag 2 in third argument, it will overwrite its first
  argument (the string to search for) with the complete name,
  here overwriting "e" with "engine_condition_pushdown". But
  as this "e" was a buffer allocated in an Item, it was not big
  enough to host the longer name, thus the crash.
  We don't need to know the complete flag's name; the output used
  from find_type() is just the flag's number (== function's return
  code). So we can pass flag 2 to find_type() in parse_name().
  After doing this fix and the other fixes in this patch, all usages
  of find_type() were using flag 2; in most usages the string to search for,
  is not guaranteed to be long enough to host the complete name
  (it is either directly from argv, or from alloc_root/my_malloc
  done in an earlier call).
  Thus, flag 2 is here made implicit: callers need not pass it anymore,
  it is always automatically turned on.
  This allows to eliminate an oddity: parse_name() took a const char**,
  and then removed "const" before calling find_type(), which could
  theoretically modify the pointed data, thus lying on constness.
  Last, constants for find_type() are now named.
sql-common/client.c:
  Two bugs:
  1) The enum was not in sync with the array (due to a bad porting of WL 1054;
  the extra OPT_ values are about options present in 5.1 and deleted in 5.5);
  added a compile_time_assert() to make sure this doesn't happen again
  2) find_type() was writing past the end of opt_arg; as opt_arg was allocated
  with alloc_root() with no extra space, this was an overrun; it could be seen
  when
  ** building with -DWITH_VALGRIND -DHAVE_purify -DEXTRA_DEBUG
  ** making execution go through the faulty code; this faulty
  code is executed only if the client asks to read a configuration
  file like this:
    mysql_options(mysql, MYSQL_READ_DEFAULT_FILE, "/tmp/cnf.cnf");
  so by adding such line to the start of mysql_client_test.c::client_connect(),
  we could see the valgrind warning:
  ==30548== Invalid write of size 1
  ==30548==    at 0x4C2624C: strcpy (mc_replace_strmem.c:303)

  ==30548==    by 0x463A7F: main (mysql_client_test.c:19902)
  This is fixed by having find_type() not overwrite anymore.
