The monotonic clock patch changed all runtime times
to abstract monotonic time. As the result user-visible
MemStats.LastGC become monotonic time as well.
Restore Unix time for LastGC.
This is the simplest way to expose time.now to runtime that I found.
Another option would be to change time.now to C called
int64 runtime.unixnanotime() and then express time.now in terms of it.
But this would require to introduce 2 64-bit divisions into time.now.
Another option would be to change time.now to C called
void runtime.unixnanotime1(struct {int64 sec, int32 nsec} *now)
and then express both time.now and runtime.unixnanotime in terms of it.
Fixes#7852.

If systems actually read that much, using 2GB-1 will
result in misaligned subsequent reads. Use 1GB instead,
which will certainly keep reads aligned and which is
plenty large enough.

For gccgo we rename exported functions so that the compiler
will make them visible. This CL adds a #define so that C
functions that #include "cgo_export.h" can use the expected
names of the function.
The test for this is the existing issue6833 test in
misc/cgo/test. Without this CL it fails when using
-compiler=gccgo.

The vi bundled with OS X has a weird bug in that if you turn off

there is no way to get the correct pkgpath. The test is not

Previously we used strndup(3) to implement C.CString for gccgo. This
is wrong because strndup assumes the string to be null terminated,
and stops at the first null terminator. Instead, use malloc
and memmove to create a copy of the string, as we do in the
gc implementation.

ClientConn. I forgot ClientConn and ServerConn were even included
in Go 1! They should've been deleted.
Scare people away from using them. The net/http package does
not use them and they're unused, unmaintained and untouched in

I fixed this data race regression in two ways: in net/http itself, and also
partially reverting the change from https://golang.org/cl/77580046 .
Previously a Read from a strings.Reader or bytes.Reader returning 0 bytes
would not be a memory write. After 77580046 it was. This reverts that back
in case others depended on that. Also adds tests.
