commit eda4928ff122a0845baf5ade83b4aa29244a3a89
Author: Olivier Bertrand <bertrandop@gmail.com>
Date:   Mon Mar 9 22:34:56 2015 +0100

- Add discovery to JSON tables
  When columns are not defined, CONNECT analyses the json file to find column definitions.
  This wors only on table that are an array of objects. Pair keys are used to generate the
  column names and pair values are used for its definition. When the LEVEL option is defined
  as a not null integer, the eventual JPATH is scanned up to the LEVEL value.

From the current one:
- Fix MDEV-7521 when column names are utf8 encoded (not a general multi-charset fix)

- Adds more to JSON discovery processing and UDF's

- Use PlugDup everywhere it replaces PlugSubAlloc + strcpy.

  Handle longjmp's raised during json processing.

   the beginning. Defining the STRING class and begining to use it (MYSQL)

2) Change the xtrace, use_tempfile and exact_info connect variables from
   GLOBAL to SESSION. Remaining GLOBAL variables have been made readonly.

3) Take care of LEX_STRING variables. The .str should not be regarded as
   allways being 0 terminated. This is handled by the Strz functions that
   make sure to return 0 terminated strings.

Bug fix:
- When inserting in MYSQL table with special column(s) a query such as:
insert into t2 values(0,4,'new04'),(0,5,'new05');
failed saying: column id (the special column) not found in t2.
It is now accepted but must be counted in values (these 0 are ignored)
- ROWID was returning row numbers based 0. Now it is from base 1.

  The code was a legacy from the first versions of the XDB engine dating 2004
  and was not working anymore with recent versions of MySQL/MariaDB. A patch
  in create had been added but is was unsatisfying, recreating all indexes on
  any alter statement and sometimes doing nothing when it should have.
  This is a major update to be tested for stability. It was in most important
  cases et all current tests pass with this new version

  It is not enough to ignore the flags while populating the table. They have
  to be removed from the definition in pre_create. The issue is to pass the
  info from the selected table handler to the created table handler.
  It is done via the only common item between them: the GLOBAL structure.
