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.

https://golang.org/cl/27206 fixed the dtoi function such that
it now properly parses negative number. Ironically, this causes
several other functions that depended on dtoi to now (incorrectly)
parse negative numbers.
For example, ParseCIDR("-1.0.0.0/32") used to be rejected prior to the
above CL, but is now accepted even though it is an invalid CIDR notation.
This CL fixes that regression.
We fix this by removing the signed parsing logic entirely from dtoi.
It was introduced relatively recently in https://golang.org/cl/12447
to fix a bug where an invalid port was improperly being parsed as OK.
It seems to me that the fix in that CL to the port handling logic was
sufficient such that a change to dtoi was unnecessary.

not a function or method call. I added a call to runtime.KeepAlive after
each such final reference (there were only three).
The code is safe today without the KeepAlive calls because the compiler
keeps arguments alive for the duration of the function. However, that is
not a language requirement, so adding the KeepAlive calls ensures that
this code remains safe even if the compiler changes in the future.

The Go HTTP/1 client will make as many new TCP connections as the user requests.
The HTTP/2 client tried to have that behavior, but the policy of
whether a connection is re-usable didn't take into account the extra 1
stream counting against SETTINGS_MAX_CONCURRENT_STREAMS so in practice
users were getting errors.
For example, if the server's advertised max concurrent streams is 100
and 200 concurrrent Go HTTP requests ask for a connection at once, all
200 will think they can reuse that TCP connection, but then 100 will
fail later when the number of concurrent streams exceeds 100.
Instead, recognize the "no cached connections" error value in the
shouldRetryRequest method, so those 100 will retry a new connection.
This is the conservative fix for Go 1.7 so users don't get errors, and
to match the HTTP/1 behavior. Issues #13957 and #13774 are the more
involved bugs for Go 1.8.
