mysqltest checks if the stmt is one that should be run in ps mode,
  but regexp doesn't match if preceeded by /* */ comment.
Fix: match function will jump over /*..*/ if found at start

Backported use of setenv() from 5.5
This will remove the leak on systems that have setenv()
I have not fixed the string.c leak, it's a local variable
   that the cleanup function cannot access.

Fixed some errors
Added note about 'no' prefix to options
See also follow-up comment to bug report

Workaround: add --loose-skip-innodb-use-native-aio
Only on linux if explicitly using --mem or setting $OPT_MEM

Add check that there is a RHS of the expression
Added to mysqltest.test

Var's string value was not 0-terminated if intially null.
While at it, also removed some reported memory leaks
Added sanity check, setting val_len=0 if val==0

Added option --debug-common which sets 'd' debug flags to the suggested list

Problem: "read-only" option ignored if it's enabled in
the command line (or in the config file).

Fix: sync opt_readonly (which is used for checks) with 
read_only (global var) when all server options are handled.

I am not fixing the test failure
Adds printing of my_errno when commands fail, could hopefully help

The problem was that mysql_upgrade failed because DROP DATABASE
refused to drop the 'performance_schema' database when the 
mysql.proc table definition was made temporarily invalid
by dump import.

This patch fixes the problem by adding the error resulting
from opening a damaged mysq.proc table (ER_CANNOT_LOAD_FROM_TABLE),
to the list of errors DROP DATABASE will ignore when trying
to lock stored procedures and functions before deletion.

This problem was a regression introduced by the patch for
Bug#57663.

Test case added to sp-destruct.test.

MSI: Only call custom action if REMOVE=ALL is specified, this avoids accidential removing services if  feature states are modified (reported by Iggy)

Fixed as suggested in the .inc file and two tests
Could not reproduce problem, but tested tests on Windows

Stripping quotes in let was a bad idea, will not fix
Added code to strip quotes from rhs in comparisons

It does work in general, the problem here was that the test name
'alter_table' matches 'main.alter_table-big' which has already been found.
Fixed by matching more explicitly (with/without suite name)
