When the coverage report file is older than the file we're
showing the coverage report for, then we show a simple message
to state this fact.

In the crash stack trace race cgocall() calls endcgo(),
this means that m->racecall is wrong.
Indeed this can happen is a goroutine is rescheduled to another M
during race call.
Disable preemption for race calls.

Before this CL, the import stack was a) not printed and b) overwritten later
in the build, destroying the information about the cycle. This CL fixes both.
I made time depend on os (os already depends on time) and with this CL the error is:
/Users/r/go/src/pkg/fmt/print.go:10:2: import cycle not allowed
package code.google.com/p/XXX/YYY:
imports fmt
imports os
imports time
imports os
Doesn't give line numbers for the actual imports, as requested in the bug, but
I don't believe that's important.
Fixes#4292.

Update #5305.
This handles the case where the nil pointers are inside a slice.
A top-level nil pointer is harder, maybe fundamentally broken by gob's model.
Thinking required.
However, a slice is the important case since people don't expect to be sending
top-level nils much, but they can arise easily in slices.

The shell's -e doesn't work across "eval"; need to error-check by hand.
The recent spate of Darwin build failures pointed out that if the first
run of cmd/dist fails, we keep going. We shouldn't.

This might fix the mkdtemp problem on the darwin builders if they
have TMPDIR set to a path ending in a slash; at worse this will
result in cleaner path names.

The tar/archive code from golang has a problem with linknames with length >
100. A pax header is added but the original header still written with a too
long field length.
As it is clear that pax support is incomplete I have added missing
implementation parts.
This commit contains code from the golang project in the folder tar/archiv.
The following pax header records are now automatically written:
- gname)
- linkpath
- path
- uname
The following fields can be written with PAX, but the default is to use the
star binary extension.
- gid (value > 2097151)
- size (value > 8589934591)
- uid (value > 2097151)
The string fields are written when the value is longer as the field or if the
string contains a char that is not encodable as 7-bit ASCII value.
The change was tested against a current ubuntu-cloud image tarball comparing
the compressed result.
+ added some automated tests for the new functionality.
Fixes#6056.

The limit is 500. There is no way to change it.
This primarily affects name resolution.
If a million goroutines try to resolve DNS names,
only 500 will get to execute cgo calls at a time.
But in return the operating system will not crash.

Jumps to the same file will use the original buffer, not the
coverage buffer. Making it work for the coverage buffer isn't
worth the trouble, especially because it would break as soon as
you jump to a different file and back.

When the packages the tested package depends on don't build,
we weren't getting out early. Added a simple check for a successful
build to an existing early out.
There may be other ways that double compilation arises, but
this fixes the one listed in the issue.

The goal is to stop only those programs that would keep
going and run the machine out of memory, but before they do that.
1 GB on 64-bit, 250 MB on 32-bit.
That seems implausibly large, and it can be adjusted.
