At the end of recovery, we initialize the transaction manager's
trid generator with the maximum trid seen during the REDO phase.
This ensures that trids always grow (needed for versioning),
even after a crash.
This patch is only preparation, as ma_recover() is not called
from ha_maria yet.
storage/maria/ha_maria.cc:
trnman_init() needs argument now (soon trnman_init() will rather
be done via ma_recover() and thus it will not be 0)
storage/maria/ma_recovery.c:
During the REDO phase, remember the max long trid of transactions
which we have seen (both in the checkpoint record and the
LOGREC_LONG_TRANSACTION_ID records)
storage/maria/ma_test1.c:
trnman_init() needs argument now
storage/maria/ma_test2.c:
trnman_init() needs argument now
storage/maria/trnman.c:
new argument to trnman_init() so that caller can decide which
value the generator of trids starts from.
storage/maria/trnman_public.h:
trnman_init() needs argument now
storage/maria/unittest/trnman-t.c:
trnman_init() needs argument now

a function to store information about transactions into buffers,
is added to the transaction manager, and called by the Checkpoint module.
storage/maria/ma_checkpoint.c:
"collecting info about transactions" moves to trnman.c
storage/maria/trnman.c:
a function to store information about the active transactions list
and committed transactions list, into buffers, for use by the
Checkpoint module.
This function needs to know how many trns there are in the committed
list, so we introduce a counter, trnman_committed_transactions.
m_string.h is needed for LEX_STRING.
storage/maria/trnman.h:
A function to store information about the active transactions list
and committed transactions list, into buffers, for use by the
Checkpoint module.
storage/maria/unittest/trnman-t.c:
trnman.h needs LEX_STRING so m_string.h
(lockmanager still fails unit tests)
