Arguably if this happens the program is buggy anyway,
but letting the panic continue looks better than interrupting it.
Otherwise things like this are possible, and confusing:
$ go run x.go
panic: $ echo $?
0

To make sure that Go code will work when moved to a
system with a case-insensitive file system, like OS X or Windows,
reject any package built from files with names differing
only in case, and also any package built from imported
dependencies with names differing only in case.

This is the same logic used in the standard tracebacks.
The caller pc is the pc after the call, so except in the
fake "call" caused by a panic, back up the pc enough
that the lookup will use the previous instruction.

Before, the mheap structure was in the bss,
but it's quite large (today, 256 MB, much of
which is never actually paged in), and it makes
Go binaries run afoul of exec-time bss size
limits on some BSD systems.

In addition to the compile failure fixed in signal*.c,
preserving the signal mask led to very strange crashes.
Testing shows that looking for SIG_IGN is all that
matters to get along with nohup, so reintroduce
sigset_zero instead of trying to preserve the signal mask.

There are two ways nohup(1) might be implemented:
it might mask away the signal, or it might set the handler
to SIG_IGN, both of which are inherited across fork+exec.
So two fixes:
* Make sure to preserve the inherited signal mask at
minit instead of clearing it.
* If the SIGHUP handler is SIG_IGN, leave it that way.

Subject Alternative Names in X.509 certificates may include IP
addresses. This change adds support for marshaling, unmarshaling and
verifying this form of SAN.
It also causes IP addresses to only be checked against IP SANs,
rather than against hostnames as was previously the case. This
reflects RFC 6125.

This is part one of two changes intended to make it easier to debug builder failures.
runOutput allows us to control the io.Writer passed to a subcommand. The intention is to add additional debugging information before and after the build which will then be capture and sent to the dashboard.
In this proposal, the only additional information is the build status. See http://build.golang.org/log/e7b5bf435b4de1913fc61781b3295fb3f03aeb6e

Benchmark results are greatly improved:
benchmark old ns/op new ns/op delta
BenchmarkSortString1K 564397 445897 -21.00%
BenchmarkSortInt1K 270889 221249 -18.32%
BenchmarkSortInt64K 26850765 21351967 -20.48%
Eyeballing a sampling of the raw number of comparisons shows a drop
on the order of 20-30% almost everywhere. The test input data that
doesn't match that are some of sawtooth/rand/plateau distributions,
where there is no change in the number of comparisons; that is,
there are no situations where this makes *more* comparisons.
