instrumentation of the of 'base' and 'base + len' in a "if (len !=
0) statement, even for cases where either 'base' or 'base + len'
are not instrumented -- because they have been previously
instrumented. Simplify the logic by putting all the statements
instrument 'base + len' inside a sequence, and then insert that
sequence right before the current insertion point. Then, to
instrument 'base + len', just get an iterator on that statement.
And do not forget to update the pointer to iterator the function
received as argument.

The mmap() call which reserves the arena should have MAP_NORESERVE
flag as in typical cases this memory will never be (fully) needed.
This matters in environments which do not do Linux style memory
overcommit, such as OpenIndiana/OpenSolaris/Solaris.
The MAP_NORESERVE flag does not exist on all operating systems
(for example FreeBSD). Therefore we define it to zero value in
case it does not exist.
Fixes issue 21.
