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.

5328df6534 runtime: check for preemption due to garbage collection
in various already expensive routines.

helps keep cpu utilization up when GOMAXPROCS > 1,
but not a full solution.

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.

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

another step to enforcing package boundaries.

fa40c856ac convert string runtime to use cgo.
now that cgo2c can handle it,
merge x.c and x_go.cgo into
a single x.cgo, for x=float,malloc,sema.
