a58d20053d win32: compilation failures, maria.test failure
include/my_global.h:
  enable compile_time_assert for all compilers
include/waiting_threads.h:
  1. don't #extern "C" system includes, they don't like it.
  2. remove any padding from WT_RESOURCE_ID structure - we want
  to compare it with memcmp
mysys/waiting_threads.c:
  assert that WT_RESOURCE_ID can be compared with memcmp
  and has no random padding bytes

27dadbd895 wt: don't support a key as a union { ulonglong, void* }. Although convenient,
it forces the user to bzero a key before setting it as a pointer, otherwise
it'll have random content on architectures where
sizeof(void*) < sizeof(ulonglong).

Declaring a key as ulonglong only (not a union) makes this user mistake
impossible.

include/waiting_threads.h:
  WT_RESOURCE_ID::value is an ulonglong, not a union
mysys/waiting_threads.c:
  WT_RESOURCE_ID::value is an ulonglong, not a union
storage/maria/ma_write.c:
  WT_RESOURCE_ID::value is an ulonglong, not a union
storage/maria/trnman.c:
  WT_RESOURCE_ID::value is an ulonglong, not a union

  relax the checks - auto init thd in will_wait_for,
  allow to destroy uninited thd (=noop),
  allow a "release" an unexistent resource (=noop),
sql/sql_class.cc:
  move wt* maintainance from maria to the server.
  do THD::cleanup after ha_close_connection() and plugin_thdvar_cleanup().

651f61fc1f wt_thd_cond_timedwait() now allows the list of blockers to change after
wt_thd_will_wait_for() was called. That is a caller doesn't need to hold a
mutex all the time preventing blockers from releasing a resource.
