        This is a prerequisite to ECDHE support in crypto/tls.

The other operating systems already ignore write failures.

Fixes #1279.

This support code helps in generating the handshake scripts
which are used for testing.

It was only used by exp/4s, and even if it is general purpose, I think
it belongs in a graphics library atop exp/draw, not in exp/draw itself.

This is largely based on ality's CL 2747042.

crypto/rc4: API break in order to conform to crypto/cipher's
Stream interface

cipher/cipher: promote to the default build

Since CBC differs between TLS 1.0 and 1.1, we downgrade and
support only 1.0 at the current time. 1.0 is what most of the
world uses.

Given this CL, it would be trival to add support for AES 256,
SHA 256 etc, but I haven't in order to keep the change smaller.

The recent linker changes broke NaCl support
a month ago, and there are no known users of it.

The NaCl code can always be recovered from the
repository history.

- Skip the gccgo tests if we don't have it
- Add -lm so nbody.c will compile
- Pass 2098 to the meteor test (cf. the shootout site)

This Flush is equivalent to zlib's Z_SYNC_FLUSH.
The addition of the explicit Writer type opens the
door to adding a PartialFlush if needed for SSH
and maybe even FullFlush.  It also opens the door
for a SetDictionary method to be added.

http://www.bolet.org/~pornin/deflate-flush.html
documents the various intricacies of flushing a
DEFLATE stream.

The code used interfaces in a pretty, pedagogical way but not efficiently.
Remove unnecessary interface code for significant speedups.
Before:

	regexp.BenchmarkLiteral	 1000000	      2629 ns/op
	regexp.BenchmarkNotLiteral	  100000	     18131 ns/op
	regexp.BenchmarkMatchClass	  100000	     26647 ns/op
	regexp.BenchmarkMatchClass_InRange	  100000	     27092 ns/op
	regexp.BenchmarkReplaceAll	  100000	     27014 ns/op

After:

	regexp.BenchmarkLiteral	 1000000	      2077 ns/op
	regexp.BenchmarkNotLiteral	  100000	     13738 ns/op
	regexp.BenchmarkMatchClass	  100000	     20418 ns/op
	regexp.BenchmarkMatchClass_InRange	  100000	     20999 ns/op
	regexp.BenchmarkReplaceAll	  100000	     21825 ns/op

There's likely more to do without major surgery, but this is a simple, significant step.
