71c941b6f6 spec: only require parens around ambiguous conversions
This is documenting the status quo. The previous cleanup
added this language as an implementation restriction, but
at least for now it is really part of the language proper.

Fixes #4605.

7576179aa3 spec: document fp rounding during explicit constant conversion
The gc compilers already behave this way. It was an explicit
decision during the very long constant design discussions,
but it appears not to have made it into the spec.

de69401b75 exp/cookiejar: implementation of SetCookies
This CL provides the rest of the SetCookies code as well as
some test infrastructure which will be used to test also
the Cookies method. This test infrastructure is optimized
for readability and tries to make it easy to review table
driven test cases.

Tests for all the different corner cases of SetCookies
will be provided in a separate CL.

e1c309e792 crypto/x509: allow MS/NS SCG key usage as ServerAuth.
By default, crypto/x509 assumes that users wish to validate
certificates for ServerAuth. However, due to historical reasons,
COMODO's intermediates don't specify ServerAuth as an allowed key
usage.

Rather NSS and CryptoAPI both allow these SGC OIDs to be equivalent to
ServerAuth.

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.
