They are making the build die. I want to be able to see that everything else is okay.

It used to not mark parameters as escaping if only one of the
fields it points to leaks out of the function. This causes
problems when importing from another package.

This provides a way to generate core dumps when people need them.
The settings are:
GOTRACEBACK=0 no traceback on panic, just exit
GOTRACEBACK=1 default - traceback on panic, then exit
GOTRACEBACK=2 traceback including runtime frames on panic, then exit
GOTRACEBACK=crash traceback including runtime frames on panic, then crash
Fixes#3257.

CL 7799045 relaxed the restriction in cmd/go on ~ in GOPATH
to allow paths with ~ in the middle while continuing to
protect against the common mistake of using GOPATH='~/home'
instead of GOPATH=~/home. Unfortunately go/build still
filters these paths out:
$ GOPATH=/tmp/test~ing go build
test.go:22:2: cannot find package "test" in any of:
/usr/lib/go/test (from $GOROOT)
($GOPATH not set)
So relax the requirement in go/build, too.

NEGL does a negation of the bottom 32 bits and then zero-extends to 64 bits,
resulting in a negative 32-bit number but a positive 64-bit number.
NEGQ does a full 64-bit negation, so that the result is negative both as
a 32-bit and as a 64-bit number.
This doesn't matter for the functions that are declared to return int32.
It only matters for the ones that return int64 or void* [sic].
This will fix the current incorrect error in the OpenBSD/amd64 build.
The build will still be broken, but it won't report a bogus error.

The database/sql/driver docs make this promise:
"Conn is a connection to a database. It is not used
concurrently by multiple goroutines."
That promises exists as part of database/sql's overall
goal of making drivers relatively easy to write.
So far this promise has been kept without the use of locks by
being careful in the database/sql package, but sometimes too
careful. (cf. golang.org/issue/3857)
The CL associates a Mutex with each driver.Conn, and with the
interface value progeny thereof. (e.g. each driver.Tx,
driver.Stmt, driver.Rows, driver.Result, etc) Then whenever
those interface values are used, the Locker is locked.
This CL should be a no-op (aside from some new Lock/Unlock
pairs) and doesn't attempt to fix Issue 3857 or Issue 4459,
but should make it much easier in a subsequent CL.
Update #3857

thread_GOOS.c becomes os_GOOS.c.
signal_GOOS_GOARCH.c becomes os_GOOS_GOARCH.c,
but with non-GOARCH-specific code moved into os_GOOS.c.
The actual arch-specific signal handler moves into signal_GOARCH.c
to avoid per-GOOS duplication.
New files signal_GOOS_GOARCH.h provide macros for
accessing fields of the very system-specific signal info structs.
Lots moving, but nothing changing.
This is a preliminarly cleanup so I can work on the signal
handling code to fix some open issues without having to
make each change 13 times.
Tested on Linux and OS X, 386 and amd64.
Will fix Plan 9, Windows, and ARM after the fact if necessary.
(Plan 9 and Windows should be fine; ARM will probably have some typos.)
Net effect: -1081 lines of code.

An earlier CL disallowed ~ anywhere in GOPATH, to avoid
problems with GOPATH='~/home' instead of GOPATH=~/home.
But ~ is only special in the shell at the beginning of each of
the paths in the list, and some paths do have ~ in the middle.
So relax the requirement slightly.

The new build tag "go1.1" will be satisfied by any Go 1.z release >= 1.1.
In general, the build tag "go1.x" will be satisfied by any Go 1.z release >= 1.x.
What happens when we reach Go 2 is yet to be decided.
The tags "go1" or "go1.0" are missing, because +build tags did not exist
before then, and also because the Go 1.0 releases do not recognize them.
The new -installsuffix flag gives access to the build context's InstallSuffix
(formerly named InstallTag, but not part of Go 1.0), for use in isolating
builds to custom directories. For example -race implies -installsuffix race,
and an AppEngine-specific build might use -tags appengine -installsuffix appengine.
Fixes#4116.
Fixes#4443.
