Bug#25452 mysql_upgrade access denied

- Improve mysql_upgrade and add comments describing it's logic
 - Don't look for mysql and mysqlcheck randomly, use dir where mysql_upgrade
  was started from
 - Don't look for mysql_fix_privilege_tables.sql randomly, compile
  in the mysql_fix_privilege_tables.sql file and use that to upgrade
  the system tables of MySQL
 - Check for any unexpected error returned from runnning the mysql_fix_privilege_tables SQL
 - Fix bug#26639, bug#24248 and bug#25405


BitKeeper/etc/ignore:
  Added scripts/comp_sql scripts/mysql_fix_privilege_tables_sql.c to the ignore list
CMakeLists.txt:
  Build files also in scripts/
Makefile.am:
  Build scripts/ a little earlier to make
  the scripts/mysql_fix_privilege_tables_sql.c file available
  when client/ is built
client/mysql_upgrade.c:
  Updated version of mysql_upgrade with comments and logical functions
include/my_global.h:
  Move IF_WIN macro to my_global.h fr from sql/mysql_priv.h
mysql-test/r/mysql_upgrade.result:
  Update result
mysql-test/t/mysql_upgrade.test:
  Add more tests for different bugs related to mysql_upgrade
scripts/Makefile.am:
  Build comp_sql and mysql_fix_privilege_tables_sql.c
sql/mysql_priv.h:
  Move IF_WIN macro to my_global.h fr from sql/mysql_priv.h
scripts/CMakeLists.txt:
  New BitKeeper file ``scripts/CMakeLists.txt''
scripts/comp_sql.c:
  New BitKeeper file ``scripts/comp_sql.c''
