Ian Lance Taylor 1635eab367 runtime: Fix defer of unlock thread at program startup.
Don't free stack allocated defer block.  Also ensure we have a
Go context in a few more places before freeing the block.

Ian Lance Taylor 05a7d56678 compiler, runtime: Use runtime functions to pass closure value.
This changes the compiler and runtime to not pass a closure
value as the last argument, but to instead pass it via
__go_set_closure and retrieve it via __go_get_closure.  This
eliminates the need for function descriptor wrapper functions.
It will make it possible to retrieve the closure value in a
reflect.MakeFunc function.

Ian Lance Taylor b0c5dc1655 runtime: Handle allocating memory in cgo/SWIG function.
A function that returns an interface type and returns a value

appearing to be in a syscall.  This patch lets that work.

Ian Lance Taylor fdbc38a6e8 compiler, runtime: Use function descriptors.
This changes the representation of a Go value of function type
from being a pointer to function code (like a C function
pointer) to being a pointer to a struct.  The first field of
the struct points to the function code.  The remaining fields,
if any, are the addresses of variables referenced in enclosing
functions.  For each call to a function, the address of the
function descriptor is passed as the last argument.

This lets us avoid generating trampolines, and removes the use
of writable/executable sections of the heap.

Ian Lance Taylor 3ab98a471c runtime: Do not reserve huge amount of swap on 32 bit architectures.
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.
