7e6bec87c1 MDEV-398: Sergv related to spacial queries
- index_merge/intersection is unable to work on GIS indexes, because:
  1. index scans have no Rowid-Ordered-Retrieval property
  2. When one does an index-only read over a GIS index, they do not 
     get the index tuple, because index only contains bounding box of the geometry.
     This is why key_copy() call crashed.
This patch fixes #1, which makes the problem go away. Theoretically, it would 
be nice to check #2, too, but SE API semantics is not sufficiently precise to do it.

d4d3ca204f Fixed lp:997460 Truncate table on partitioned Aria table fails with ER_ILLEGAL_HA
Fix is done by doing an autocommit in truncate table inside Aria

storage/maria/ha_maria.cc:
  Force a commit for TRUNCATE TABLE inside lock tables
  Check that we don't call TRUNCATE with concurrent inserts going on.
  Make ha_maria::implict_commit faster when we don't have Aria tables in the transaction.
  (Most of the patch is just re-indentation because I removed an if level)

22e793639a Added new options to KILL. New syntax is KILL [HARD|SOFT] [CONNECTION|QUERY] [ID | USER user_name]
- If USER is given, all threads for that user is signaled
- If SOFT is used then the KILL will not be sent to the handler. This can be used to not interrupt critical things in the handler like 'REPAIR'.

Internally added more kill signals. This gives us more information of why a query/connection was killed.
- KILL_SERVER is used when server is going down. In this case the users gets ER_SHUTDOWN as the reason connection was killed.
- Changed signals to number in correct order, which makes it easier to test how the signal should affect the code.
- New error message ER_CONNECTION_KILLED if connection was killed by 'KILL CONNECTION'. Before we got error ER_SHUTDOWN.

b95d2778aa Fixes bugs found by testcase for lp:815022 and lp:726374 "ma_blockrec.c:3000: write_block_record: Assertion `cur_block[1].page_count == 0' failed with a multi-index Aria workload"
The issues was:
- For some tables with a lot of not packed fields, we didn't allocate enough memory in head page which caused DBUG_ASSERT's
- Removed wrong DBUG_ASSERT()
- Fixed a problem with underflow() where it generates a key page where all keys didn't fit.
- Max key length is now limited by block_size/3  (was block_size /2).  This is required for underflow() to work with packed keys.




mysql-test/lib/v1/mysql-test-run.pl:
  Remove --alignment=8 as this doesn't work on 64 bit systems
mysql-test/suite/maria/r/small_blocksize.result:
  Test case for Aria bug
mysql-test/suite/maria/t/small_blocksize-master.opt:
  Test case for Aria bug
mysql-test/suite/maria/t/small_blocksize.test:
  Test case for Aria bug
storage/maria/ha_maria.cc:
  Fixed comment
storage/maria/ma_bitmap.c:
  Fixed wrong variable usage in find_where_to_split_row() where we allocated too little memory for head page.
  We did not take into account space for head extents (long VARCHAR) when trying to split row on head page. This caused us to allocate too little space from bitmap which lead to ASSERT failures later.
storage/maria/ma_blockrec.c:
  Made some argument const (to ensure they was not accidently changed)
  Removed wrong DBUG_ASSERT()
storage/maria/ma_blockrec.h:
  Removed not used variable
storage/maria/ma_delete.c:
  Added my_afree() in case of error
  More comments and DBUG_ASSERT() for underflow()
storage/maria/ma_open.c:
  Make keyinfo->underflow_block_length smaller for packed keys. This has to be done as for long packed keys, underflow() otherwise generates a key page where all keys didn't fit.
storage/maria/ma_page.c:
  New DBUG_ASSERT()
storage/maria/ma_write.c:
  Fixed comment
storage/maria/maria_def.h:
  We have to have space for at least 3 keys on a key page.
  (Otherwise the underflow() code doesn't work for packed keys, even when we have an underflow() for an empty key page)
