This bug happened due to incompleteness of the fix for bug 872735:
the occurrences of the fields in the conditions of correlated
subqueries were not taken into account when recalculating
covering keys bit maps.

This bug manifested itself with queries containing non-correlated
IN subqueries over materialized views/derived tables.  
The bug happened because the code of the function generate_derived_keys did
not take into account that the function could be called twice when the
optimizer was deciding whether in-exist transformation should be applied.

Print server version name to .err file on crash 

scripts/make_binary_distribution.sh:
  Remove extra MariaDB- from binary tar.gz file name
sql/mysqld.cc:
  Print server version name to .err file on crash (to ensure people paste also that when they report a crash)

Fixed wrong parameter type for --general-log. Now one can enable it with --general-log= 1 | true | on
Fixed that bool parameters can also take 'on' and 'off' as parameters. This is in line with the values assigned to them in mysqld.


mysys/my_getopt.c:
  Fixed that bool parameters can also take 'on' and 'off' as parameters.
sql/mysqld.cc:
  Fixed wrong info message for mysqld --general-log
  Fixed wrong parameter type for --general-log. Now one can enable it with --general-log= 1 | true | on

This bug happened because the maps of covering keys for mergeable derived
tables/views was not recalculated after the derived tables/vies had been
merged into the main query.
