BUG#9826  Server crash on schema change ("drop table", "alter table") with NDB

See note on 10948 for detailed explanation.

struct a { void* a; long long b[1]; };

on PPC32 (and 32bit pa risc): 16
on x86: 12

so a malloc(sizeof(void*)+extra_bits) is wrong.

Assuming that the long long is 64 bit aligned as non-aligned 64bit accesses
are rather expensive on ppc.

Thanks to paulus for doing the PPC port of valgrind.
Without which I would no doubt still be trying to find this.

Ensure that 'null_value' is not accessed before val() is called in FIELD() functions
Fixed initialization of key maps. This fixes some problems with keys when you have more than 64 keys
Fixed that ROLLUP don't always create a temporary table. This fix ensures that func_gconcat.test results are now predictable

    - support additional platforms (OpenBSD, Darwin)
    - make use of /proc/cpuinfo CPU flag information
      (needed to distinguish EMT64 Xeons from normal ones)
    - chose the right CPU related options depending on 
      GCC version and target architecture
    - check if the chosen CPU type is actually supported
      by the GCC version , fallback to CPUs predecessor
      until test compile succeeds

Mainly cleanups for gcc 4.0. Some small pieces from looking at -Wall. Removed a number of dumb things in ha_tina.

Fixed two deadlocks.
