In thread.c, we need to cast to whatever the native
size of intptr is on the system, but we only have
uintptr available. They're the same size, but can't
do signed casts without this one :).

the signal handling stack is a different size than
the normal stack, so it cannot be allocated using
the backup stack allocator.
Fixes#250.

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! ;)

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.

selfree maintains a cache of Select structures for several sizes. In
newselect, we'll use an entry from the cache if one is found. However,
the Scase structures corresponding to a send may have been allocated
for the wrong size. In this case we'll write off the end of the Scase
into random memory and, generally, read some amount of junk in the
receive.
This patch fixes the issue by removing the cache, on the advice of
rsc.

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.

* in 6l, -K already meant check for stack underflow.
add -KK to mean double-check stack overflows
even in nosplit functions.
* comment out print locks; they deadlock too easily
but are still useful to put back for special occasions.
* let runcgo assembly switch to scheduler stack
without involving scheduler directly. because runcgo
gets called from matchmg, it is too hard to keep it
from being called on other stacks.
