1, IMO, the fatal error "regfree: not a register" from 5g when
compiling runtime/debug.go is due to gcc miscompile, it doesn't
show up when compiled with -O0. But I still haven't thought of
a way to fix this, should all ARM builds be built with -O0?
2, fixed mksysnum_linux.pl, so zsysnum_linux_arm.go no longer
needs to be hand-generated.
3, regen all in pkg syscall for Linux/ARM on Debian 6.0
This CL is somewhat big, I'd like to split it if necessary.

This was an implementation detail that snuck into the public interface.
*Writer.Create gives you an io.Writer, the *Writer itself was never
meant to be written to.

Makes files like src/pkg/syscall/ztypes_linux_amd64.go easier to read.
(The copy that is checked in predates the //line output mode,
so this also preserves the status quo.)

Also update build to be able to run mkbuiltin again.
The export form has changed a little, so builtin.c has
more diffs than unsafe.go.
In CL 5650069, I just edited the documentation, a rarely
successful method of change.

Restore package os/signal, with new API:
Notify replaces Incoming, allowing clients
to ask for certain signals only. Also, signals
go to everyone who asks, not just one client.
This could plausibly move into package os now
that there are no magic side effects as a result
of the import.
Update runtime for new API: move common Unix
signal handling code into signal_unix.c.
(It's so easy to do this now that we don't have
to edit Makefiles!)
Tested on darwin,linux 386,amd64.
Fixes#1266.

1) Remove the Reset() member in crypto/aes and crypto/des (and
document the change).
2) Turn several empty error structures into vars. Any remaining error
structures are either non-empty, or will probably become so in the
future.
3) Implement SetWriteDeadline for TLS sockets. At the moment, the TLS
status cannot be reused after a Write error, which is probably fine
for most uses.
4) Make crypto/aes and crypto/des return a cipher.Block.

one trie lookup per rune is needed. See forminfo.go for a description
of the new format. Also included leading and trailing canonical
combining class in decomposition information. This will often avoid
additional trie lookups.

hammerCompareAndSwapPointer64 was only passing on
little-endian systems. hammerCompareAndSwapPointer32 was
writing 8 bytes to a uint32 value on the heap.
