Since 2a8c81ff handshake messages are not written directly to wire but
buffered.  If an error happens at the wrong time the alert will be
written to the buffer but never flushed, causing an EOF on the client
instead of a more descriptive alert.

Thanks to Brendan McMillion for reporting this.

When cmd/compile generates position-independent code on linux
(the -shared flag), it refers to runtime.tlsg as a TLS IE variable.

When cmd/link is linking a PIE executable internally, all TLS IE
relocations are generated by cmd/compile, and the variable they
refer to, runtime.tlsg, is local to the binary. This means we can
optimize this particular IE case to LE, and thus implement IE
support when internally linking.

To do this optimization in the linker, we need to rewrite the
PC-relative MOVD to a constant load. This may seem like an
unconscionable act born of enthusiasm, but it turns out this is
standard operating procedure for linkers. GNU gold does exactly
the same optimization. I spent some time reading it and documented
at least one missing feature from this version.

Also, flesh out the baked-in /etc/services table for LookupPort a bit.

This services map moves from a unix-specific file to a portable file
where nacl can use it.

Also, remove the duplicated entries in the protocol map in different
cases, and just canonicalize the input before looking in the map. Now
it handles any case, including MiXeD cAse.

In the process, add a test that service names for LookupPort are case
insensitive. They were on Windows, but not cgo. Now there's a test and
they're case insensitive in all 3+ paths. Maybe it breaks plan9. We'll
see.

This CL adds a script to run vet on std and cmd.

There are a considerable number of false positives,
mostly from legitimate but unusual assembly in
the runtime and reflect packages.

There are also a few false positives that need fixes.
They are noted as such in the whitelists;
they're not worth holding this CL for.

The unsafe pointer check is disabled.
The false positive rate is just too high to be worth it.

There is no cmd/dist/test integration yet.
The tentative plan is that we'll check the local platform
during all.bash, and that there'll be a fast builder that
checks all platforms (to cover platforms that can't exec).
