As we've dropped support for Mac OS X 10.5, I think the generated .pkg
     should reflect that decision.
     But this CL make it impossible to generate pkg on Mac OS X 10.6, at least
     for me.

The generated syscall files for Windows are still breaking "go tool api"
(unknown function []byte); I'll look at fixing that separately.

1) The -D argument should always be a pseudo-import path,
like _/Users/rsc/foo/bar, never a standard import path,
because we want local imports to always resolve to pseudo-paths.

2) Disallow local imports in non-local packages.  Otherwise
everything works but you get two copies of a package
(the real one and the "local" one) in your binary.

To make sure that there is no resource leak,
I suggest to fix the 'fakedb' driver such as it fails when any
Stmt is not closed.
First, add a check in fakeConn.Close().
Then, fix all missing Stmt.Close()/Rows.Close().
I am not sure that the strategy choose in fakeConn.Prepare/prepare* is ok.
The weak point in this patch is the change in Tx.Query:
  - Tests pass without this change,
  - I found it by manually analyzing the code,
  - I just try to make Tx.Query look like DB.Query.

In a transaction, on a Stmt.Query error, it was possible for a
connection to be added to a db's freelist twice. Should use
the local releaseConn function instead.

Thanks to Gwenael Treguier for the failing test.

Also in this CL: propagate driver errors through releaseConn
into *DB.putConn, which conditionally ignores the freelist
addition if the driver signaled ErrBadConn, introduced in a
previous CL.

We should check the CRC32s of files on EOF, even if there's no

We now always write the "optional" streaming data descriptor
signature, which turns out to be required for OS X.

Also, handle reading the data descriptor with or without the
signature, per the spec's recommendation. Fix data descriptor
reading bugs found in the process.

It may have to switch stacks, since we are calling
a DLL instead of a system call.

badcallback says where it is, because it is being called

When a very low-level system call that should never fail
does fail, we call notok, which crashes the program.
Often, we are then left with only the program counter as
information about the crash, and it is in notok.
Instead, inline calls to notok (it is just one instruction
on most systems) so that the program counter will
tell us which system call is unhappy.

doc: convert to use godoc built-in templates

tmpltohtml is gone, to avoid having a second copy of the code.
Instead, godoc -url /doc/go1.html will print the actual HTML
served for that URL.  "make" will generate files named go1.rawhtml
etc, which can be fed through tidy.

It can be hard to tell from the codereview diffs, but all the
tmpl files have been renamed to be html files and then
have "Template": true added.
