Make the panic detectable, and use that in ioutil.ReadFile to
give an error if the file is too big.

This fixes the bug Rob ran into when editing package bytes.
Regexp imports regexp/syntax, which imports bytes, and
regexp/syntax was not being properly recompiled during a
test of a change to package bytes.

summary:     gc: fix infinite recursion for embedded interfaces

This is causing 'interface type loop' errors during compilation
of a complex program.  I don't understand what's happening
well enough to boil it down to a simple test case, but undoing
this change fixes the problem.

The change being undone is fixing a corner case (uses of
pointer to interface in an interface definition) that basically
only comes up in erroneous Go programs.  Let's not try to
fix this again until after Go 1.

Unfixes issue 1909.

        We already use GOHOSTOS to represent the host OS that the toolchain
        will be run on, so no need to resort to uname(1) to get that (and
        use uname(1) will make cross-compiling for another host impossible).

- use proper Win64 gcc calling convention when
  calling initcgo on amd64
- increase g0 stack size to 64K on amd64 to make
  it the same as 386
- implement C.sleep
- do not use C.stat, since it is renamed to C._stat by mingw
- use fopen to implement TestErrno, since C.strtol
  always succeeds on windows
- skip TestSetEnv on windows, because os.Setenv
  sets windows process environment, while C.getenv
  inspects internal C runtime variable instead

instead of the origin.

This makes YCbCr match the other image types (e.g. RGBA, Gray) in
that an image's bounds is not restricted to the positive quadrant.

Also optimize the YCbCr draw code by hoisting some computation
outside of the loop.

benchmark              old ns/op    new ns/op    delta
draw.BenchmarkYCbCr      2544418      2373558   -6.72%

Like https://golang.org/cl/4681044/ I don't think a gofix is
feasible. People will have to make manual changes. On the other hand,
directly manipulating YCbCr images is relatively rare, compared to
RGBA images, and if other code just uses the jpeg and draw packages
instead of messing directly with a YCbCr's []byte representations,
then things should just continue to work.

Remove NewMD5, NewSHA1 and NewSHA256 in favor of using New and
explicitly importing the used hash-function. This way when using, for
example, HMAC with RIPEMD there's no md5, sha1 and sha256 linked in
through the hmac package.

A gofix rule is included, and applied to the standard library (3 files
altered).

This change is the result of a discussion at
https://golang.org/cl/5550043/ to pull the discussion about
deprecating these functions out of that issue.
