Bumped up version number to 0.2.1

1) Buffer Pool size now defaults to 1GB and a minimum of 64MB
2) Log files are 3 by default and each 128MB in size
3) Removed innodb-file-io-threads config variable since no longer used
4) Set read io and write io threads to 8 by default for better default performance
5) Set log buffer size to 16 MB by default and minimum to 2MB
6) Set additional memory buffer pool to 8 MB and minimum to 2MB
7) Set max dirty percent to 75% and decreased to 99% to never allow a completely dirty buffer pool
8) Increased io capacity to 200 for a good default

Changed defaults on Solaris and Forte to be CC and cc instead of cc-5.0

Replaced abs_top_srcdir with top_srcdir, not sure it's an
improvement but at least it's known that abs_top_srcdir
in cases have a problem and this is a more common variable
to use for the same purpose.

Use AC_TRY_RUN instead of AC_TRY_LINK when checking for x86 PAUSE instruction support, due to http://bugs.opensolaris.org/bugdatabase/printableBug.do?bug_id=6478684 .

etc.  The sparc_* are defined only for sparc, but the sun_* are generic for x86
and sparc (and are defined empty for any other platform).

include/probes_mysql_nodtrace.h:
  Regenerated with dheadgen.pl
scripts/dheadgen.pl:
  Set the executable bit.
sql/Makefile.am:
  Since libndb.la is a libtool library, we should process objects in .libs/.
  Removed '-n' from the echo command since the Solaris version does not understand it.
  Changed the order of dependencies so that dtrace_files and dtrace_providers are
  created before probes_all.o

the magic script.

Disabling ndb DTrace probes temporarily
Hacking some DTrace Makefile magic to make it work
All temporary solutions to make it work quickly

for files in tar command as part of make of a source distribution.
Only 99 characters are supported. Abbreviated performance version
by pv thus. Should be ok since shorter than ndb, and if MySQL Cluster
Carrier Grade Edition has thus 1 character longer version names.

of standard malloc.

Removed instance manager from builds

platforms and emphasize the fact that gcc is the default
compiler on all platforms.

Make it possible to say --compiler=SunStudio instead of
--compiler=forte

Fix a bug that lost an important flag for C++ builds.

for those cases when gcc, cc-5.0, icpc or icc isn't in the path.

Fixed handling of 32 and 64 bits.

Downgraded Solaris builds on Forte to use -xO2 rather than -xO3.

Made it possible to build 64-bits on Mac OS X

Fixed some bugs in setting CC, CXX, ASFLAGS, LDFLAGS

Fixed bugs relating to use of SunStudio/Forte in check-cpu

Reorganized code a bit

Removed the use of --with-fast-mutexes since they aren't really
fast, rather slow.

Added -static-libgcc when using gcc

Added optimising compilation flags on BSD

Added use of curses library on Solaris

Removed the use of MY_ATOMIC_MODE_RWLOCKS which removed use of
atomic instructions

Added support for Forte on Solaris/x86

removed from SHOW ENGINE InnoDB STATUS
