12518e441b runtime cleanup.
* move memory code into $GOOS-specific directory.
  * allow printing of static strings < 256 bytes.
    (dynamic strings will bump maxstring as they are allocated.)
  * use cgo2c for runtime.mal.

08579c26dd runtime: if os/signal is not in use, crash on
most signals, so that ordinary programs
	can be killed, for example.

Fixes #434.

5a4a08fab8 Fix stack on FreeBSD / add stack check across the board
FreeBSD was passing stk as the new thread's stack base, while
stk is the top of the stack in go. The added check should cause
a trap if this ever comes up in any new ports, or regresses
in current ones.

0489a260da FreeBSD-specific porting work.
cgo/libmach remain unimplemented. However, compilers, runtime,
and packages are 100%. I still need to go through and implement
missing syscalls (at least make sure they're all listed), but
for all shipped functionality, this is done. Ship! ;)

3f7a32405d runtime: warn about SELinux based mmap failures on Linux.
SELinux will cause mmap to fail when we request w+x memory unless the
user has configured their policies. We have a warning in make.bash,
but it's quite likely that the policy will be reset at some point and
then all their binaries start failing.

This patch prints a warning on Linux when mmap fails with EACCES.

f529224039 Get the right sigaction struct for the 386 rt_sigaction system
call.  This uses the header files from a 32-bit Ubuntu Hardy
system.

The use of _LOOSE_KERNEL_NAMES seems right.  The
-D__ARCH_SI_UID_T works around a bug which appears to be fixed
in later Linux versions.

22a5c78f44 rename sys functions to runtime,
because they are in package runtime.

133a158bd8 8c, 8l dynamic loading support.
better mach binaries.
cgo working on darwin+linux amd64+386.
eliminated context switches - pi is 30x faster.
add libcgo to build.

on snow leopard:
  - non-cgo binaries work; all tests pass.
  - cgo binaries work on amd64 but not 386.

1b14bdbf1c changes to accommodate nacl:
* change ldt0setup to set GS itself; nacl won't let us do it.
  * change breakpoint to INT $3 so 8l can translate to HLT for nacl.
  * panic if closure is needed on nacl.
  * do not try to access symbol table on nacl.
  * mmap in 64kB chunks.

nacl support:
  * system calls, threading, locks.

bbcb91a3a7 convert 386 to use %gs instead of %fs for extern register.
required for nacl and may be nicer for ffi,

46e392e01c changed 5c calling convention to use stack exclusively for in
params. a number of fixes to assembly routines that assumed R0
had the first arg. one stack offset fix, arm pushes the link
register on stack top.
