Don't use PATH_MAX for FN_REFLEN as this uses too much stack space

Larger stack size neaded for open table on x86 64 bit
Fix failing test cases
Deleted symlink from bk


BitKeeper/etc/ignore:
  added libmysqld/ha_blackhole.cc
BitKeeper/deleted/.del-ha_blackhole.cc~727c69ef7846623a:
  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:
  Update results after error message changes
sql/ha_federated.cc:
  Fix error messages to be more consistent
sql/mysql_priv.h:
  Stack size to have when opening a table
  (This was needed on x86 64 bit Linux)
sql/share/errmsg.txt:
  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
