It was pthread_mutex_t in mi_static.c and 
mysql_mutex_t in my_thr_init.c

Solaris linker complains about different size of the 
symbol.

Fix : use mysql_mutex_t everywhere.

Post-merge fix: wait for statement result before disconnecting. Otherwise the statement might affect unrelated tests. mysql-test/t/lock_multi.test, Reap statement status

Remove per-project SAFEMALLOCs definitions, as they result in malloc/free mismatches.

Updated suppressed warning messages.

Added extra checks of 64-bit atomic support on GCC and Solaris, also added 64-bit support in solaris.h which was missing

BUG#49591, Fixed version string in SHOW CREATE TABLE to accomodate for column list partitioning and new function to_seconds

The test allowed random coincidence of connection ids for two concurrent
sessions performing CREATE/DROP temp tables.

Fixed with correcting the test. The sessions connection ids are not changed
from their defaults anymore.

                  
When compressed myisam files are opened, they are always memory mapped
sometimes causing memory swapping problems.

When we mmap the myisam compressed tables of size greater than the memory 
available, the kswapd0 process utilization is very high consuming 30-40% of 
the cpu. This happens only with linux kernels older than 2.6.9

With newer linux kernels, we don't have this problem of high cpu consumption
and this option may not be required.
 
The option 'myisam_mmap_size' is added to limit the amount of memory used for
memory mapping of myisam files. This option is not dynamic.

The default value on 32 bit system is 4294967295 bytes and on 64 bit system it
is 18446744073709547520 bytes.

Note: Testcase only tests the option variable. The actual bug has be to 
tested manually.
