Russ Cox 5963dbac08 runtime: turn divide by zero, nil dereference into panics
tested on linux/amd64, linux/386, linux/arm, darwin/amd64, darwin/386.
freebsd untested; will finish in a separate CL.

for now all the panics are errorStrings.
richer structures can be added as necessary
once the mechanism is shaked out.

Russ Cox 718be3215f in C and asm, replace pkg·name with ·name
(eliminate assumption of package global name space,
make code easier to move between packages).

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

Fixes #434.

Devon H. O'Dell 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.

Adam Langley 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.

Ian Lance Taylor 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.

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

Russ Cox 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.

Russ Cox 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.

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