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.

The problem is not actually related to 2byte collation IDs.
The same crash happens if you change the collation ID in
mysql-test/str_data/Index.xml to a value smaller than 256.

Crash happened in SQL parser, because the "ident_map" and "state_map"
arrays were not initialized in loadable utf8 collations.

Fix: adding proper initialization of the "ident_map" and "state_map"
members for loadable utf8 collations.
