John Kelly c8dd89ed3d net/http: add Cookie.Valid method
The (*http.Cookie).String method used by SetCookie will silently discard
or sanitize any fields it deems invalid, making it difficult to tell
whether a cookie will be sent as expected.

This change introduces a new (*http.Cookie).Valid method which may be
used to check if any cookie fields will be discarded or sanitized prior
to calling (*http.Cookie).String.

Fixes #46370

Roberto Clapis 542693e005 net/http: make SameSiteDefaultMode behavior match the specification
The current specification does not foresee a SameSite attribute without
a value. While the existing implementation would serialize SameSite in a
way that would likely be ignored by well-impelemented clients, it is
better to not rely on this kind of quirks.

Specification: https://tools.ietf.org/html/draft-ietf-httpbis-rfc6265bis-05#section-4.1.1

Stephan Renatus 3d5703babe net/http: add support for SameSite option in http.Cookie
The same-site cookie attribute prevents a cookie from being sent along with
cross-site requests. The main goal is mitigate the risk of cross-origin
information leakage and provides some protection against cross-site request
forgery attacks.

This change adds the option to http.Cookie so it can be stored and
passed to HTTP clients.

Spec: https://tools.ietf.org/html/draft-ietf-httpbis-cookie-same-site-00

Volker Dobler 8f6d68ebaa net/http: send more cookie values in double quotes
According to RFC 6255 a cookie value may contain neither spaces " "
nor commas ",". But browsers seem to handle these pretty well and such
values are not uncommon in the wild so we do allow spaces and commas
in cookie values too. Up to now we use the double-quoted wire format
only for cookie values with leading and/or trailing spaces and commas.
Values with internal spaces/commas are sent without the optional double
quotes. This seems to be a problem for some agents.

This CL changes the behaviour for cookie values with spaces or commas:
Such values are always sent in double quotes. This should not have
any impact on existing agents and the increases of data transmitted
is negligible.

Fixes #18627

Josh Chorlton d86a6ef0c7 net/http: fix cookie Expires minimum year to 1601 instead of Epoch year 1970
Following RFC 6265 Section 5.1.1.5, ensure that the minimum

A detailed specification for parsing the Expiry field is at:

Brad Fitzpatrick 519474451a all: make copyright headers consistent with one space after period
This is a subset of https://golang.org/cl/20022 with only the copyright
header lines, so the next CL will be smaller and more reviewable.

Go policy has been single space after periods in comments for some time.

The copyright header template at:

    https://golang.org/doc/contribute.html#copyright

also uses a single space.

Make them all consistent.
