Users (like myself) may be tempted to think the higher-numbered curve
is somehow better or more secure, but P256 is currently the best
ECDSA implementation, due to its better support in TLS clients, and a
constant time implementation.
For example, sites that present a certificate signed with P521
currently fail to load in Chrome stable, and the error on the Go side
says simply "remote error: tls: illegal parameter".
Fixes#19901.

NSS (used in Firefox and Chrome) won't accept two certificates with the same
issuer and serial. But this causes problems with self-signed certificates
with a fixed serial number.
This change randomises the serial numbers in the certificates generated by
generate_cert.go.

Also use 2048-bit RSA keys as default in generate_cert.go,
as recommended by the NIST.

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.
Fixes#4658.

* add -work option to save temporary files (Fixes issue 2980)
* fix go test -i to work with cgo packages (Fixes issue 2936)
* do not overwrite/remove empty directories or non-object
files during build (Fixes issue 2829)
* remove package main vs package non-main heuristic:
a directory must contain only one package (Fixes issue 2864)
* to make last item workable, ignore +build tags for files
named on command line: go build x.go builds x.go even
if it says // +build ignore.
* add // +build ignore tags to helper programs

We replace the current Open with:
OpenFile(name, flag, perm) // same as old Open
Open(name) // same as old Open(name, O_RDONLY, 0)
Create(name) // same as old Open(name, O_RDWR|O_TRUNC|O_CREAT, 0666)
This CL includes a gofix module and full code updates: all.bash passes.
(There may be a few comments I missed.)
The interesting packages are:
gofix
os

New logging interface simplifies and generalizes.
1) Loggers now have only one output.
2) log.Stdout, Stderr, Crash and friends are gone.
Logging is now always to standard error by default.
3) log.Panic* replaces log.Crash*.
4) Exiting and panicking are not part of the logger's state; instead
the functions Exit* and Panic* simply call Exit or panic after
printing.
5) There is now one 'standard logger'. Instead of calling Stderr,
use Print etc. There are now triples, by analogy with fmt:
Print, Println, Printf
What was log.Stderr is now best represented by log.Println,
since there are now separate Print and Println functions
(and methods).
6) New functions SetOutput, SetFlags, and SetPrefix allow global
editing of the standard logger's properties. This is new
functionality. For instance, one can call
log.SetFlags(log.Lshortfile|log.Ltime|log.Lmicroseconds)
to get all logging output to show file name, line number, and
time stamp.
In short, for most purposes
log.Stderr -> log.Println or log.Print
log.Stderrf -> log.Printf
log.Crash -> log.Panicln or log.Panic
log.Crashf -> log.Panicf
log.Exit -> log.Exitln or log.Exit
log.Exitf -> log.Exitf (no change)
This has a slight breakage: since loggers now write only to one
output, existing calls to log.New() need to delete the second argument.
Also, custom loggers with exit or panic properties will need to be
reworked.
All package code updated to new interface.
The test has been reworked somewhat.
The old interface will be removed after the new release.
For now, its elements are marked 'deprecated' in their comments.
Fixes#1184.
