Move startNano from runtime to time package.
In preparation for a subsequent change that speeds up Since and Until.
This also makes code simpler as we have less assembly as the result,
monotonic time handling is better localized in time package.
This changes values returned from nanotime on windows
(it does not account for startNano anymore), current comments state
that it's important, but it's unclear how it can be important
since no other OS does this.

A timezone with a zero offset from UTC and without a three-letter
abbreviation will have a numeric name in timestamps: "+00".
There are currently two of them:
$ zdump Atlantic/Azores America/Scoresbysund
Atlantic/Azores Wed Aug 22 09:01:05 2018 +00
America/Scoresbysund Wed Aug 22 09:01:05 2018 +00
These two timestamp are rejected by Parse, since it doesn't allow for
zero offsets:
parsing time "Wed Aug 22 09:01:05 2018 +00": extra text: +00
This change modifies Parse to accept a +00 offset in numeric timezone
names.
As side effect of this change, Parse also now accepts "GMT+00". It was
explicitely disallowed (with a unit test ensuring it got rejected),
but the restriction seems incorrect.
DATE(1), for example, allows it:
$ date --debug --date="2009-01-02 03:04:05 GMT+00"
date: parsed date part: (Y-M-D) 2009-01-02
date: parsed time part: 03:04:05
date: parsed zone part: UTC+00
date: input timezone: parsed date/time string (+00)

time.Parse currently rejects numeric timezones names with UTC offsets
bigger than +12, but this is incorrect: there's a +13 timezone and a
+14 timezone:
$ zdump Pacific/Kiritimati
Pacific/Kiritimati Mon Jun 25 02:15:03 2018 +14
For convenience, this cl changes the ranges of accepted offsets from
-14..+12 to -23..+23 (zero still excluded), i.e. every possible offset
that makes sense. We don't validate three-letter abbreviations for the
timezones names, so there's no need to be too strict on numeric names.
This change also fixes a bug in the parseTimeZone, that is currently
unconditionally returning true (i.e. valid timezone), without checking
the value returned by parseSignedOffset.
This fixes 5 of 17 time.Parse() failures listed in Issue #26032.

fmt's %d, %x, and %X all accept pointer arguments. However, in cmd/vet's
printVerbs table, they were defined as if they did not accept pointer
arguments.
This inconsistency with fmt did not manifest to users since the vet
codebase worked around it. In particular, pointer arguments were usually
allowed for verbs that accepted integers, as the *types.Pointer argument
type case read the following:
t&(argInt|argPointer) != 0
As a result, using the %q verb with a pointer resulted in a bug in
cmd/vet:
$ go run f.go
%!q(*int=0xc000014140)
$ go vet f.go
[no warning]
As documented, fmt's %q verb only accepts runes (integers), strings, and
byte slices. It should not accept pointers, and it does not. But since
vet mixed integers and pointers, it wasn't properly warning about the
misuse of fmt.
This patch surfaced another bug with fmt.Printf("%p", nil):
$ go run f.go
%!p(<nil>)
$ go vet f.go
[no warning]
As documented, fmt's %p verb only accepts pointers, and untyped nil is
not a valid pointer. But vet did not warn about it, which is another
inconsistency with fmt's documented rules. Fix that too, with a test,
also getting rid of the TODO associated with the code.
As a result of those changes, fix a wrong use of the fmt format verbs in
the standard library, now correctly spotted by vet.
Fixes#25233.

The go/printer (and thus gofmt) uses a heuristic to determine
whether to break alignment between elements of an expression
list which is spread across multiple lines. The heuristic only
kicked in if the entry sizes (character length) was above a
certain threshold (20) and the ratio between the previous and
current entry size was above a certain value (4).
This heuristic worked reasonably most of the time, but also
led to unfortunate breaks in many cases where a single entry
was suddenly much smaller (or larger) then the previous one.
The behavior of gofmt was sufficiently mysterious in some of
these situations that many issues were filed against it.
The simplest solution to address this problem is to remove
the heuristic altogether and have a programmer introduce
empty lines to force different alignments if it improves
readability. The problem with that approach is that the
places where it really matters, very long tables with many
(hundreds, or more) entries, may be machine-generated and
not "post-processed" by a human (e.g., unicode/utf8/tables.go).
If a single one of those entries is overlong, the result
would be that the alignment would force all comments or
values in key:value pairs to be adjusted to that overlong
value, making the table hard to read (e.g., that entry may
not even be visible on screen and all other entries seem
spaced out too wide).
Instead, we opted for a slightly improved heuristic that
behaves much better for "normal", human-written code.
1) The threshold is increased from 20 to 40. This disables
the heuristic for many common cases yet even if the alignment
is not "ideal", 40 is not that many characters per line with
todays screens, making it very likely that the entire line
remains "visible" in an editor.
2) Changed the heuristic to not simply look at the size ratio
between current and previous line, but instead considering the
geometric mean of the sizes of the previous (aligned) lines.
This emphasizes the "overall picture" of the previous lines,
rather than a single one (which might be an outlier).
3) Changed the ratio from 4 to 2.5. Now that we ignore sizes
below 40, a ratio of 4 would mean that a new entry would have
to be 4 times bigger (160) or smaller (10) before alignment
would be broken. A ratio of 2.5 seems more sensible.
Applied updated gofmt to all of src and misc. Also tested
against several former issues that complained about this
and verified that the output for the given examples is
satisfactory (added respective test cases).
Some of the files changed because they were not gofmt-ed
in the first place.
For #644.
For #7335.
For #10392.
