30a9957aac bytes: minor optimization to lastIndexFunc
Before and after:
BenchmarkTrimSpace  20000000   81.3 ns/op
BenchmarkTrimSpace  50000000   58.0 ns/op

(most whitespace trimming is ASCII whitespace)

Same optimization appeared a handful of other places
in this file, but not here.

0592c44956 net: permit pollster DelFD to return whether to call Wakeup
This is necessary for systems that use select as the pollster,
such as Solaris (supported by gccgo).  It corresponds to the
bool returned by AddFD.  In general it's not clearly defined
what happens when a descriptor used in a select is closed, and
different systems behave differently.  Waking up the select
will cause the right thing to happen: the closed descriptor
will be dropped from the next iteration.

8c6489bc27 exp/cookiejar: infrastructure for upcoming implementation
This CL is the first of a handful of CLs which will provide
the implementation of cookiejar. It contains several helper
functions and the skeleton of Cookies and SetCookies.

Proper host name handling requires the ToASCII transformation
from package idna which currently lives in the go.net
subrepo. This CL thus contains just a TODO for this issue.

da35d42521 exp/inotify: close event channel before file descriptor
Closing the inotify file descriptor can take over a second
when running on Ubuntu Precise in an NFS directory, leading to
the test error in issue 3132.  Closing the event channel first
lets a client that does not care about the error channel move
on.

d1e16d06b4 net/http: fix Server blocking after a Handler's Write fails
If a Handle's Write to a ResponseWriter fails (e.g. via a
net.Conn WriteDeadline via WriteTimeout on the Server), the
Server was blocking forever waiting for reads on that
net.Conn, even after a Write failed.

Instead, once we see a Write fail, close the connection,
since it's then dead to us anyway.

572d984eaa cmd/gc: fix escape analysis
If the analysis reached a node twice, then the analysis was cut off.
However, if the second arrival is at a lower depth (closer to escaping)
then it is important to repeat the traversal.

The repeating must be cut off at some point to avoid the occasional
infinite recursion. This CL cuts it off as soon as possible while still
passing all tests.

5ae6a23731 syscall: regenerate ztype files for linux
This CL adds TCPInfo struct to linux/386,arm.
It's already added to linux/amd64.

Note that not sure the reason but cgo godefs w/ latest gcc
translates a flexible array member in structures correctly,
handles it as a non-incomplete, non-opaque type, on Go 1.
This CL reverts such changes by hand for the Go 1 contract.

they are both buggy behavior in the Go 1.0 versions; the old results

It was left over from when the compiler emitted more
aggressive set and not used errors, and it was keeping
the optimizer from removing a redundant zeroing of n
when n was a pointer or integer variable.
