Joe Tsai b03129aa27 compress/flate: make library RFC1951 compliant 
Corrected several issues:
 * RFC1951 section 3.2.7 dictates that it is okay for the HDist tree to have a
single code of zero bits. Furthermore, the behavior of the C zlib library
permits empty trees even when there are more than one codes.
 * RFC1951 section 3.2.5 shows that HLit codes 286 and 287 are invalid. Thus,
Go's implementation should choke on inputs using these codes.
 * RFC1951 section 3.2.5 and 3.2.7 are ambiguous about whether the number of
HDist codes can be greater than 30. The C zlib library (which is the canonical
reference implementation) performs this check here:
62d6112a79/inflate.c (L906)

In addition, a number of test cases were added to the unit tests that exercises
these edge cases. The test cases listed in TestStreams will either fail or
succeed in a manner matching the behaviour of the C zlib version. Given that the
C zlib implementation is the reference for the world, Go's implementation should
match C zlib behaviour.

Fixes #11030

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin

See https://golang.org/doc/install or doc/install.html for more details.
