c974b8b6ac cmd/go: diagnose import cycles better
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.

d00bd1d1f4 cmd/gc: better error messages for C-style if statements.
Given

The old message was
        x.go:6: syntax error: unexpected semicolon or newline before {
Now we see

bc6bb3efb4 math/big: fix nil bug in GobEncode
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.

24f302a69d cmd/dist: join with TMPDIR more carefully to avoid // in path.

a07c95a53c archive/tar: Fix support for long links and improve PAX support.
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.
