Fixed bugs found by buildbot:

- Use -Wno-uninitialized if -DFORCE_INIT_OF_VARS is not used, to avoid warnings about not initialized variables.
- Fixed compiler warnings
- Added a name for each thr_lock to get better error messages (This is needed to find out why 'archive.test' sometimes fails)


BUILD/SETUP.sh:
  Use -Wno-uninitialized if -DFORCE_INIT_OF_VARS is not used, to avoid warnings about not initialized variables.
BUILD/build_mccge.sh:
  Use -Wno-uninitialized if -DFORCE_INIT_OF_VARS is not used, to avoid warnings about not initialized variables.
client/mysqltest.cc:
  Fixed bug in remove_files_wildcards (the orignal code never removed anything)
extra/libevent/devpoll.c:
  Fixed compiler warning
include/thr_lock.h:
  Added a name for each thr_lock to get better error messages.
mysql-test/suite/maria/t/maria3.test:
  Speed up test.
mysys/thr_lock.c:
  Added a name for each thr_lock to get better error messages.
  Added a second 'check_locks' to find if something goes wrong in 'wake_up_waiters'.
sql/lock.cc:
  Added a name for each thr_lock to get better error messages.
storage/xtradb/fil/fil0fil.c:
  Fixed compiler warning
