Implementing Lookup/LookupId is not done, which would
require parsing /adm/users. It is unclear of how much benefit

The net package consists of thin three layers like the follwoing;
- Exposed API, that contains net.Dial, net.DialUDP, net.DialUnix
- Socket and network file descriptor, that contains net.netFD and
its methods, helper functions such as dialUDP, dialUnix
- Network pollster, that contains net.pollDesc and its methods
This CL removes redundant argument check which is already done by
API layer.

Update the original change but do not read interface types in
the arguments area. Once the arguments area is zeroed as the
locals area is we can safely read interface type values there
too.

machine http://play.golang.org/p/GrNFakAYLN
rv1 := reflect.ValueOf(complex128(0))
rt := rv1.Type()
rv2 := rv1.Convert(rt)
rv3 := reflect.New(rt).Elem()
rv3.Set(rv2)
Running the code fails with the following:
panic: reflect: internal error: storeIword of 16-byte value
I've tested on a 64bit machine and verified this fixes the panic. I
haven't tested on a 32bit machine so I haven't verified the other
cases, but they follow logically.

Add eq, lt, etc. to allow one to do simple comparisons.
It's basic types only (booleans, integers, unsigned integers,
floats, complex, string) because that's easy, easy to define,
and covers the great majority of useful cases, while leaving
open the possibility of a more sweeping definition later.

This is potentially an API-breaking change, but it is an important bug fix.
The CL https://golang.org/cl/7305072/ added stuff to make
the tar file look more like a file system internally, including providing an
implementation of os.FileInfo for the file headers within the archive.
But the code is incorrect because FileInfo.Name is supposed to return
the base name only; this implementation returns the full path. A round
trip test added in the same shows this in action, as the slashes are
preserved as we create a header using the local implementation of
FileInfo.
The CL here changes the behavior of the tar (and zip) FileInfo to honor
the Go spec for that interface. It also clarifies that the FileInfoHeader
function, which takes a FileInfo as an argument, will therefore create
a header with only the base name of the file recorded, and that
subsequent adjustment may be necessary.
There may be code out there that depends on the broken behavior.
We can call out the risk in the release notes.
Fixes#6180.
