go/doc: steps towards collecting methods of embedded types
No visible external changes yet. The current approach is
a stop-gap approach: For methods of anonymous fields to be
seen, the anonymous field's types must be exported.
Missing: computing the actual MethodDocs and displaying them.
(Depending on the operation mode of godoc, the input to go/doc
is a pre-filtered AST with all non-exported nodes removed. Non-
exported anonymous fields are not even seen by go/doc in this
case, and it is impossible to collect associated (even exported)
methods. A correct fix will require some more significant re-
engineering; AST filtering will have to happen later, possibly
inside go/doc.)

template: better error message for empty templates
New("x").ParseFiles("y") can result in an empty "x" template.
Make the message clearer that this is the problem. The error
returns from both template packages in this case were
confusing.
I considered making the method use "x" instead of "y" in
this case, but that just made other situations confusing
and harder to explain.

vim: fix go filetype detection
The filetype needs to be set during BufRead in order for the did_filetype() check to prevent the file being detected as a conf file. One example where this can occur is if a cgo file has a #include at the top of the file. The # is detected in vim's generic configuration (conf file) toward the bottom of filetype.vim
