fix excessive relinking that results from rerunning
dtrace -G second time on the objects that come into 
static library. 
The reason for relinking is that dtrace -G changes 
timestamp for the object file, which in turn results
in re-archiving the mysys on next time make runs, 
which causes relinking of the whole mysql, because
everything depends on mysys.

The fix is to copy objects into temp before running 
dtrace -G in mysqld pre-build step. This way dtrace 
does not affect the object timestamp.

the ugly Solaris dtrace workarounds

Rerun dtrace -G on all  objects that can contan dtrace probes (also objects that are
part of static libs) before linking mysqld to produce dtrace_probes_all.o and link 
dtrace_probes_all.o with mysqld

This ugly workaround was inspired by handling dtrace using autotools.

Bug#35591 FLUSH PRIVILEGES caused a crash

A race condition on the privilege hash tables (proc_priv_hash
and func_priv_hash) caused one thread to try to delete elements
that had already been deleted by another thread.

The bug was caused by reading and saving the pointers to 
the hash tables outside mutex protection.  This led to an
inconsistency where a thread copied a pointer to a hash,
another thread did the same, the first thread then deleted
the hash, and the second then crashed when it in turn tried to
delete the deleted hash.

The fix is to ensure that operations on the shared hash structures
happens under mutex protection (moving the locking up a little)

empty element produces a warning)

Implemented a new INFORMATION_SCHEMA table, which is intended to
provide information about tablespaces.

mysql-test/r/information_schema.result:
  Updated test result according to WL#2511. With this WL
  I_S has new TABLESPACES schema.
mysql-test/r/information_schema_db.result:
  Updated test result according to WL#2511. With this WL
  I_S has new TABLESPACES schema.
mysql-test/r/mysqlshow.result:
  Updated test result according to WL#2511. With this WL
  I_S has new TABLESPACES schema.
mysql-test/suite/funcs_1/r/is_columns_is.result:
  Updated test result according to WL#2511. With this WL
  I_S has new TABLESPACES schema.
mysql-test/suite/funcs_1/r/is_tables_is.result:
  Updated test result according to WL#2511. With this WL
  I_S has new TABLESPACES schema.
sql/handler.h:
  Added SCH_TABLESPACES to enum_schema_tables.
sql/mysql_priv.h:
  Added human readable definitions for I_S.TABLESPACES field
  identifiers.
sql/sql_show.cc:
  Added I_S.TABLESPACES schema. The code which handles I_S.FILES
  is capable to handle I_S.TABLESPACES as well. Thus we reuse
  this code and let functions/variables have more generic names.
