new option --maria-force-start-after-recovery-failures=N; number of consecutive recovery failures (failures
of log reading or recovery processing, anything in [translog_init(),maria_recovery_from_log()])
is stored in the control file; if at a Maria start they are more than N, logs are removed. This is for automated
systems which have to run whatever happens. As tables risk staying corrupted, --maria-recover should also
be used on them: this revision makes maria-recover work (it was disabled).
Fixed bug in translog_is_log_files(). translog_init() now prints message to error log if failed.
Removed \0 in the output of SHOW ENGINE MARIA LOGS; removed hard-coded engine name there.

KNOWN_BUGS.txt:
  As option --maria-force-start-after-recovery-failures is added, it corresponds to the wish "we should fix that if this happens etc".
  LOAD INDEX is not ignored since a few weeks. Listed concurrency bugs have been fixed some time ago.
  Recovery of fulltext and GIS indexes works since a few weeks.
mysql-test/include/maria_make_snapshot.inc:
  configurable prefix in table's name (so far 't' or 't_corrupted')
mysql-test/include/maria_make_snapshot_for_comparison.inc:
  configurable prefix in table's name (so far 't' or 't_corrupted')
mysql-test/include/maria_make_snapshot_for_feeding_recovery.inc:
  configurable prefix in table's name (so far 't' or 't_corrupted')
mysql-test/include/maria_verify_recovery.inc:
  configurable prefix in table's name (so far 't' or 't_corrupted')
mysql-test/lib/mtr_report.pl:
  new test maria-recover.test generates expected corruption warnings in the error log. maria-recovery.test's corrupted table is renamed to t_corrupted1 instead of t1.
mysql-test/r/maria-preload.result:
  result update. maria_pagecache_read* values are similar to the previous version of this file, though a bit bigger
  because using the information_schema and the join leads to some internal maria temp table being used, and thus some
  blocks of it being read.
mysql-test/r/maria-purge.result:
  engine's name in SHOW ENGINE MARIA LOGS changed.
mysql-test/r/maria-recover.result:
  result for new test. We see corruption messages at first SELECT and then none at second SELECT, expected.
mysql-test/r/maria-recovery.result:
  result update
mysql-test/r/maria.result:
  new variables show up
mysql-test/t/disabled.def:
  BUG#34911 is not fixed but the test had been made independent of the bug (workaround). A new bug (crash) has popped recently, so it has to stay
  disabled (BUG#35107).
mysql-test/t/maria-preload.test:
  Work around BUG#34911 "FLUSH STATUS doesn't flush what it should":
  compute differences in status variables before and after relevant queries
mysql-test/t/maria-recover-master.opt:
  test --maria-recover
mysql-test/t/maria-recover.test:
  Test of the --maria-recover option (build a corrupted table and see if it is auto-repaired)
mysql-test/t/maria-recovery-big.test:
  update for new API of include/maria*.inc
mysql-test/t/maria-recovery-bitmap.test:
  update for new API of include/maria*.inc
mysql-test/t/maria-recovery.test:
  update for new API of include/maria*.inc. Corrupted table t1 renamed to t_corrupted1, so that mtr_report.pl
  does not blindly remove all corruption messages for t1 which is
  a common name.
storage/maria/ha_maria.cc:
  Enabling maria-recover.
  Adding option and global variable --maria_force_start_after_recovery_failures: ha_maria_init()
  calls mark_recovery_start() and mark_recovery_success() to keep track of failed consecutive recoveries
  and remove logs if needed.
  Removed \0 in the output of SHOW ENGINE MARIA LOGS; removed hard-coded engine name there.
storage/maria/ma_checkpoint.c:
  new prototype
storage/maria/ma_control_file.c:
  Storing in one byte in the control file, the number of consecutive recovery failures.
storage/maria/ma_control_file.h:
  new prototype
storage/maria/ma_init.c:
  new prototype
storage/maria/ma_locking.c:
  Need to update open_count on disk at first write and close for transactional tables, like we already did for
  non-transactional tables, otherwise we cannot notice that the table is dubious.
storage/maria/ma_loghandler.c:
  translog_is_log_files() is made more generic to serve either to search or to delete logs (the latter is
  for --maria-force-start-after-recovery-failures). It also had a bug (always returned FALSE).
storage/maria/ma_loghandler.h:
  export function because ha_maria::mark_recovery_start() needs it
storage/maria/ma_recovery.c:
  changing name of maria_recover() to distinguish from the maria-recover option.
storage/maria/ma_recovery.h:
  changing name of maria_recover() to distinguish from the maria-recover option.
storage/maria/ma_test_force_start.pl:
  Test of --maria-force-start-after-recovery-failures (and also, to be realistic, of --maria-recover).
  This is standalone because mysql-test-run does not support testing that multiple mysqld restarts expectedly failed.
  I'll have to run it on my machine and also on a Windows machine.
storage/maria/unittest/ma_control_file-t.c:
  adding recovery_failures to the test
storage/maria/unittest/ma_test_loghandler_multigroup-t.c:
  fix for compiler warning (unused variable in non-debug build)
