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

mysys/my_wincond.c:
  race condition: block gate could be left open forever, if cond_broadcast
  was done right after the last thread left WaitForMultipleObjects() on timeout
mysys/thr_rwlock.c:
  make rwlocks behave similar to their distant linux/solaris relatives

It was a forgotten rw_unlock(), due to the deadlock detector feature (so bug was only in 5.1-maria, not
6.0-maria).

mysql-test/suite/maria/r/maria3.result:
  result, all fine
mysql-test/suite/maria/t/maria3.test:
  Test of BUG#39697: two scenarios (transactional tables, and non-transactional table but dynamic row format so still taking the rwlock) where the hang happened.
  t2 added by this test was masked by a temporary table created earlier in the test, which we forgot to drop.
storage/maria/ha_maria.cc:

storage/maria/ma_blockrec.c:

storage/maria/ma_init.c:

storage/maria/ma_open.c:

storage/maria/ma_write.c:
  if local_lock_tree is true, we have acquired keyinfo->root_lock so need to release it before "goto err".
  A pair of assertions so that our usage of TrIDs is kept sensible.
storage/maria/maria_def.h:
  A macro so that changes of MARIA_HA::trn can be tracked with --debug. It helped to understand in what cases,
  in maria_write(), we could have !(info->dup_key_trid == info->trn->trid) && !share->now_transactional
  (answer: ALTER TABLE adding UNIQUE index on transactional table).

mysys/lf_alloc-pin.c:
  workaround for gcc 4.1.0 strict-aliasing bug.
  and yes, I mean a *bug* - as union (in alloc_free) is a
  documented way to access type-punned pointers. and it helps in
  newer gcc, but fails in 4.1.0

automake *must* know all sources in advance, listing a file in EXTRA_DIST
doesn't make it a source, which breakes dependency tracking
(.Po files aren't included)

it forces the user to bzero a key before setting it as a pointer, otherwise

impossible.

(sanja's patch)

There is no test cases as it's not trivial to do a test case for this.
The new code for Maria is however executed by the test case in the bug report.

mysql-test/mysql-test-run.pl:
