  Delete: libmysqld/ha_blackhole.cc
include/my_global.h:
  Don't use PATH_MAX for FN_REFLEN as this uses too much stack space.
  (With a PATH_MAX of 4096, we use 80K for opening a table as there is several objects of size FN_REFLEN on stack)
mysql-test/r/federated.result:
  Update results after error message changes
mysql-test/r/grant.result:
  Update results after error message changes
mysql-test/r/grant2.result:

  Remove quotes around error string for federated as two quotes in the output looks strange
sql/sql_base.cc:
  More correct stack size
sql/sql_parse.cc:
  Set thread_stack before store_globals()
sql/unireg.h:
  More correct MAX_DBKEY_LENGTH
