6bbd12f176 exp/cookiejar: make cookie sorting deterministic.
Re-enable TestUpdateAndDelete, TestExpiration, TestChromiumDomain and
TestChromiumDeletion on Windows.

Sorting of cookies with same path length and same creation
time is done by an additional seqNum field.
This makes the order in which cookies are returned in Cookies
deterministic, even if the system clock is manipulated or on
systems with a low-resolution clock.

The tests now use a synthetic time: This makes cookie testing
reliable in case of bogus system clocks and speeds up the
expiration tests.

556dd0bfbd runtime: fix sigaction struct on freebsd
Fix the sa_mask member of the sigaction struct - on FreeBSD this is
declared as a sigset_t, which is an array of four unsigned ints.
Replace the current int64 with Sigset from defs_freebsd_GOARCH, which
has the correct definition.

Unbreaks the FreeBSD builds.

The O(n+m) complexity is obtained probabilistically
by using Rabin-Karp algorithm, which provides the needed complexity
unless exceptional collisions occur, without memory allocation.

6d888f1e1b build: clang support
This works with at least one version of clang
that existed at one moment in time.
No guarantees about clangs past or future.

To try:
        CC=clang all.bash

It does not work with the Xcode clang,
because that clang fails at printing a useful answer
to:
        clang -print-libgcc-file-name
The clang that works prints a full path name for
that command, not just "libgcc.a".

Fixes #4713.

c7f7bbbf03 runtime: fix build on linux
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.

f3407f445d runtime: fix running under nohup
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.

Fixes #4491.

5b20a18f3b crypto/x509: support IP SANs.
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.

ea0292c61b misc/dashboard/builder: record build result on dashboard
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
