This rolls back https://golang.org/cl/27117 partly, softening it so it
only retries POST/PUT/DELETE etc requests where there's no Body (nil
or NoBody). This is a little useless, since most idempotent requests
have a body (except maybe DELETE), but it's late in the Go 1.8 release
cycle and I want to do the proper fix.
The proper fix will look like what we did for http2 and only retrying
the request if Request.GetBody is defined, and then creating a new request
for the next attempt. See https://golang.org/cl/33971 for the http2 fix.

The combination of two prior CLs can cause panics:
* CL/17873: make chained multiReader Read more efficient
* CL/28533: make MultiReader nil exhausted Readers for earlier GC
The first CL allows MultiReader to "inherit" another MultiReader's list of Readers
for efficiency reasons. This is problematic when combined with the
later CL since that can set prior Readers in that list to nil for GC reasons.
This causes panics when two MultiReaders are used together (even synchronously).
To fix this, rather than setting consumed Readers as nil, we set them with
a special eofReader that always returns EOF.

While processing a symbol for a function, if it is determined
that a function would make the text section too large then
a new text section is created and the address of the function
is in the new text section. But the symbol for the function
is marked as being in the previous text section, causing
incorrect codegen for the function and leading to a segv if
that function is called. This adds code to set the sym.Sect
field to the new section if a new one is created. Note that
this problem only happens at the point where a new section is
created.

When we copy the stack, we need to adjust all BPs.
We correctly adjust the ones on the stack, but we also
need to adjust the one that is in g.sched.bp.
Like CL 33754, no test as only kernel-gathered profiles will notice.
Tests will come (in 1.9) with the implementation of #16638.
The invariant should hold that every frame pointer points to
somewhere within its stack. After this CL, it is mostly true, but
something about cgo breaks it. The runtime checks are disabled
until I figure that out.

Previously it was possible to craft a DSA private key that would cause
Sign() to loop forever because no signature could be valid. This change
does some basic sanity checks and ensures that Sign will always
terminate.
Thanks to Yolan Romailler for highing this.
Be aware, however, that it's still possible for an attacker to simply
craft a private key with enormous values and thus cause Sign to take an
arbitrary amount of time.

For reasons that I do not know, OpenBSD does not call pthread_create
directly, but instead looks it up in libpthread.so. That means that we
can't use the code used on other systems to retry pthread_create on
EAGAIN, since that code simply calls pthread_create.
This patch copies that code to an OpenBSD-specific version.
Also, check for an EAGAIN failure in the test, as that seems to be the
underlying cause of the test failure on several systems including OpenBSD.
