godef[1][2] is a third party tool for printing information about
expressions, especially the location of their definition. This can be
used to implement a "jump to definition" function. Unlike
cross-language solutions like ctags, godef does not require an index,
operates on the Go AST instead of symbols and works across packages,
including the standard library.
This patch implements two new public functions: godef-describe (C-c
C-d) and godef-jump (C-d C-j). godef-describe describes the expression
at point, printing its type, and godef-jump jumps to its definition.

On NetBSD tv_sec is already an int64 so no need for a test.
On OpenBSD, semasleep expects a Unix time as argument,
and 1<<30 is in 2004.

Usually, there is no esc info when inlining, but there will be when generating inlined wrapper functions.
If we don't use this information, we get invalid addresses on the stack.

The example is the same as the FileServer one, but
it's relevant for both.
Also use strings.TrimPrefix while I'm here.

Now that revision 0c029965805f is in, it's easy
to guarantee that we never access a driver.Conn
concurrently, per the database/sql/driver contract,
so we can remove this overlarge mutex.

If LookPath in Command fails, sets a sticky error, and then
StdinPipe, StdoutPipe, or StderrPipe were called, those pipe
fds were never cleaned up.

The current SysAlloc implementation suffers from a signed vs unsigned
comparision bug. Since the error code from mmap is negated, the
unsigned comparision of v < 4096 is always false on error. Fix this
by switching to the darwin/freebsd/linux mmap model and leave the mmap
return value unmodified.

The rule is not concistently followed by gc.
It appears that gccgo is ignoring it. go/types
does not implement this rule. However, both
gccgo and now go/types can compile/type-check
the entire std library (and thus all the shift
expressions occuring in it) w/o errors. For
more details see the discussion in issue 4883.
Fixes#4880.

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

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.
