I would like opinions on whether this is a good idea for 1.1.
On the one hand it's a moderately important issue. On the
other hand this introduces at least the possibility of
external linker errors due to the additional relocations and
it may be better to wait.
I'm fairly confident that the behaviour is unchanged when not
using an external linker.
Update #5221
This CL is tested lightly on 386 and amd64 and fixes the cases
I tested. I have not tested it on Darwin or Windows.

PC-relative needs a signed offset; others need unsigned.
Also fix signedness of 32-bit relocation on Windows.

Some 64-bit fields were run through 32-bit words, some counts were
not checked for overflow, and relocations must fit in 32 bits.
Tests to follow.

A few places in the linker pushed 64-bit values through 32-bit holes,
including in relocation.
Clean them up, and check for a few other overflows as well.
Tests to follow.

runtime.setmg() calls another function (cgo_save_gm), so it must save
LR onto stack.
Re-enabled TestCthread test in misc/cgo/test.

The refcounting of driver Conns was completedly busted and
would leak (be held open forever) with any reasonable
load. This was a significant regression from Go 1.0.
The core of this patch is removing one line:
s.db.addDep(dc, s)
A database conn (dc) is a resource that be re-created any time
(but cached for speed) should not be held open forever with a
dependency refcount just because the Stmt (s) is alive (which
typically last for long periods of time, like forever).
The meat of the patch is new tests. In fixing the real issue,
a lot of tests then failed due to the fakedb_test.go's paranoia
about closing a fakeConn while it has open fakeStmts on it. I
could've ignored that, but that's been a problem in the past for
other bugs.
Instead, I now track per-Conn open statements and close them
when the the conn closes. The proper way to do this would've
been making *driverStmt a finalCloser and using the dep mechanism,
but it was much more invasive. Added a TODO instead.
I'd like to give a way for drivers to opt-out of caring about
driver.Stmt closes before a driver.Conn close, but that's a TODO
for the future, and that TODO is added in this CL.
I know this is very late for Go 1.1, but database/sql is
currently nearly useless without this.
I'd like to believe all these database/sql bugs in the past
release cycle are the result of increased usage, number of
drivers, and good feedback from increasingly-capable Go
developers, and not the result of me sucking. It's also hard
with all the real drivers being out-of-tree, so I'm having to
add more and more hooks to fakedb_test.go to simulate things
which real drivers end up doing.

We have to reset the global lineno variable before
processing each file otherwise line numbers will be
offset by the number of lines in the previous file.
The following examples are from the beginning of the
ztime_linux_amd64.c file which is generated from
time.goc in the runtime package.
Before:
#line 2483 "/home/apm/src/go/src/pkg/runtime/time.goc"
static Timers timers;
static void addtimer ( Timer* ) ;
void
time·Sleep(int64 ns)
{
#line 2492 "/home/apm/src/go/src/pkg/runtime/time.goc"
After:
#line 16 "/home/apm/src/go/src/pkg/runtime/time.goc"
static Timers timers;
static void addtimer ( Timer* ) ;
void
time·Sleep(int64 ns)
{
