Merge of 5.1-main into 5.1-maria. There were no changes to storage/myisam, or mysql-test/t/*myisam*.

However there were three new tests mysql-test/suite/parts/t/partition*myisam.test, of which I make here
copies for Maria.

 /*
+  There was a problem on MacOSX with a shared object ha_example.so.
+  It used hash_search(). During build of ha_example.so no libmysys
+  was specified. Since MacOSX had a hash_search() in the system
+  library, it built the shared object so that the dynamic linker
+  linked hash_search() to the system library, which caused a crash
+  when called. To come around this, we renamed hash_search() to
+  my_hash_search(), as we did long ago with hash_insert() and
+  hash_reset(). However, this time we made the move complete with
+  all names. To keep compatibility, we redefine the old names.
+  Since every C and C++ file, that uses HASH, needs to include
+  this file, the change is complete. Both names could be used
+  in the code, but the my_* versions are recommended now.
