  Fixing non-deterministic test results

sql/sql_yacc.yy
  Initializing fname_first using get_tok_end() instead of get_ptr().
  The latter is grammar-dependant. The former is not.

Difficult to debug due to lacking report
This does not solve the real issue, but extracts server log when it happens
Forst commit was incomplete, didn't cover all cases

This was affected by same problem as append_file etc.
Added Q_ERROR to special handling, and added small test

Tried to use an expression inside ""
Go via variable, and add $exe to the output

Disallow (and don't use) space in combination names

 - Remove the "hack" from mtr.pl that skipped searching for the .dll files
  when embedded and windows. Now the variables will be preoperly initialized.
 - Make the tests detect that they can't run on windows+embedded
