Moved the key statistics update to info().
The table is not locked in open(). This made wrong stats possible.

No test case for the test suite.
This happens only with heavy concurrency.
A test script is added to the bug report.


mysql-test/r/heap_hash.result:
  Bug#10178 - failure to find a row in heap table by concurrent UPDATEs
  Updated test results to reflect the new  statistics behaviour.
mysql-test/t/heap_hash.test:
  Bug#10178 - failure to find a row in heap table by concurrent UPDATEs
  Added a FLUSH TABLES to avoid statistics differences between normal 
  and ps-protocol tests.
sql/ha_heap.cc:
  Bug#10178 - failure to find a row in heap table by concurrent UPDATEs
  Moved the key statistics update to info().
  The table is not locked in open(). This made wrong stats possible.
sql/ha_heap.h:
  Bug#10178 - failure to find a row in heap table by concurrent UPDATEs
  Added an element to track the validity of the key statistics.

include/my_global.h:
  an improvement (bug #7851: C++ 'new' conflicts with kernel header asm/system.h).
  redefine 'new' before #include <asm/atomic.h> in any case.

into mysql.com:/home/timka/mysql/src/4.1-bug-11185

The source of the problem is in Field_longlong::cmp. If 'this' is
an unsigned number, the method casts both the current value, and
the constant that we compare with to an unsigned number. As a
result if the constant we compare with is a negative number, it
wraps to some unsigned number, and the comparison is incorrect.

When the optimizer chooses the "range" access method, this problem
causes handler::read_range_next to reject the current key when the
upper bound key is a negative number because handler::compare_key
incorrectly considers the positive and negative keys to be equal.

The current patch does not correct the source of the problem in
Field_longlong::cmp because it is not easy to propagate sign
information about the constant at query execution time. Instead
the patch changes the range optimizer so that it never compares
unsiged fields with negative constants. As an added benefit,
queries that do such comparisons will execute faster because
the range optimizer replaces conditions like:
(a) (unsigned_int [< | <=] negative_constant) == FALSE
(b) (unsigned_int [> | >=] negative_constant) == TRUE
with the corresponding constants.
In some cases this may even result in constant time execution.


mysql-test/r/range.result:
  - Changed incorrect result of an old test
  - Added new results for BUG#11185
mysql-test/t/range.test:
  - Added new tests for BUG#11185
  - Deleted an old comment because now the problem is fixed
sql/opt_range.cc:
  Added a new optimization to the range optimizer where we detect that
  an UNSIGNED field is compared with a negative constant. Depending on
  the comparison operator, we know directly that the result of the
  comparison is either TRUE or FALSE for all input values, and we need
  not check each value.
  
  This optimization is also necessary so that the index range access
  method produces correct results when comparing unsigned fields with
  negative constants.
