to pick up some new security fixes that are in it.

Patch provided by Georgi Kodinov.

Update the year in the copyright notice, file "README".

$SUBJ$
1. Took a diff between the previous base version and the
mysql sources.
2. Added the new 2.1.4 base version.
3. Reviewed and re-applied the diff from step #1.

AND 5.5 YASSL FIXES.

Took the 5.5 yassl code and applied it to the 5.0 codebase, keeping the
compilation files.

Fix for #36428/#38364 backported into 5.0.

SMALL KEY CACHE

The server crashed on division by zero because the key cache was not
initialized and the block length was 0 which was used in a division.

The fix was to not allow CACHE INDEX if the key cache was not initiallized.
Thus never try LOAD INDEX INTO CACHE for an uninitialized key cache.

Also added some windows files/directories to .bzrignore.

Buffer over-run on all platforms, crash on windows, wrong result on other platforms,
when rounding numbers which start with 999999999 and have
precision = 9 or 18 or 27 or 36 ...

Bug#11765687 (MySQL58677): No privilege on table / view, but can know #rows / underlying table's name

1 - If a user had SHOW VIEW and SELECT privileges on a view and
this view was referencing another view, EXPLAIN SELECT on the outer
view (that the user had privileges on) could reveal the structure
of the underlying "inner" view as well as the number of rows in
the underlying tables, even if the user had privileges on none of
these referenced objects.

This happened because we used DEFINER's UID ("SUID") not just for
the view given in EXPLAIN, but also when checking privileges on
the underlying views (where we should use the UID of the EXPLAIN's
INVOKER instead).

We no longer run the EXPLAIN SUID (with DEFINER's privileges).
This prevents a possible exploit and makes permissions more
orthogonal.

2 - EXPLAIN SELECT would reveal a view's structure even if the user
did not have SHOW VIEW privileges for that view, as long as they
had SELECT privilege on the underlying tables.

Instead of requiring both SHOW VIEW privilege on a view and SELECT
privilege on all underlying tables, we were checking for presence
of either of them.

We now explicitly require SHOW VIEW and SELECT privileges on
the view we run EXPLAIN SELECT on, as well as all its
underlying views. We also require SELECT on all relevant
tables.

Backport a fix for Bug 57094 from 5.5.

# message:
#   Fix for Bug 57094 (Copyright notice incorrect?).
#   
#   The fix is to:
#     - introduce ORACLE_WELCOME_COPYRIGHT_NOTICE define to have a single place
#       to specify copyright notice;
#     - replace custom copyright notices with ORACLE_WELCOME_COPYRIGHT_NOTICE
#       in programs.

The buffer was simply too small.
In 5.5 and trunk, the size is 311 + 31,
in 5.1 and below, the size is 331

Follow-up patch that adds the newly added header file to
Makefile.am noinst_HEADERS.

CLIENT TOOLS
      
The fix is to backport part of revision:
        
  - alexander.nozdrin@oracle.com-20101006150613-ls60rb2tq5dpyb5c
      
from mysql-5.5. In detail, we add the oracle welcome notice
header file proposed in the original patch and include/use it
in client/mysqlbinlog.cc, replacing the existing and obsolete
notice.
