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.

Now we see

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.

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.

Rows.Close.
Previously, callers that followed the example code (but not call
rows.Close after "for rows.Next() { ... }") could leak statements if
the driver returned an error other than io.EOF.

This CL rearranges the call order for raw networking primitives like
the following;
- For dialers that open active connections, pollDesc.Init will be
called before syscall.Connect.
- For stream listeners that open passive stream connections,
pollDesc.Init will be called just after syscall.Listen.
- For datagram listeners that open datagram connections,
pollDesc.Init will be called just after syscall.Bind.
This is in preparation for runtime-integrated network pollster for BSD
variants.

I tried to make it absolutely correct but there are too many
conflicting definitions for the official list of time zones.
Since when we're parsing we know when to expect
a time zone and we know what they look like if not exactly
what the definitive set is, we compromise. We accept any
three-character sequence of upper case letters, possibly
followed by a capital T (all four-letter zones end in T).
There is one crazy special case (ChST) and the possibility
of a signed hour offset for GMT.
Fixes#3790
