Update unicode/tables.go to reflect changes in the Unicode Standard up to
Unicode 15.0.0, released 13 Sept 2022.
In order to accommodate this update, strconv/isPrint has been updated to
reflect changes in printable characters.
Also changed is template/exec_test.go for both text and html packages- in
the test "TestJSEscaping", rune U+FDFF was used as a placeholder for an
unprintable character. This codepoint was assigned and made printable in
Unicode 14.0.0, breaking this test. It has been replaced with the assigned
and never-printable U+FFFE to fix the test and provide resiliency in the
future.
This upgrade bypasses Unicode 14.0.0, but is compatible.

Fixes a bug that was introduced in CL 410414; in that CL, to avoid
a race condition in the initialization of the lexer, the setting
of the breakOK and continueOK options was moved to before
Tree.funcs was populated from parameters. As a result, the parser
missed the fact that 'break' and 'continue' were defined as functions.
Following CL 421883 race conditions are no longer an issue, so
the simplest fix is just to move the initialization where it was
before - in startParse, after t.funcs has been set.

The concurrent model for delivering tokens was fine for pedagogy,
but has caused a few problems as the package has evolved (that is,
got more complicated). It's easy to eliminate it, simplifying or
removing some of the hacks used to work around these prolems.
The old lexer would deliver tokens over a channel to the parsing
goroutine, and continue running until EOF. In this rewrite, we
instead run the machine until a token is ready, and shut it down
until the next token is needed. The mechanism is just to return nil
as the state function, which requires a bit more threading of return
values through the state functions but is not difficult. The change
is modest.
A couple of error messages change, but otherwise the change has no
external effect. This is just an internal cleanup, long overdue.

The existing code errors out immediately if the argument is not
"comparable", making it impossible to test a slice, map, and so
on from being compared to nil.
Fix by delaying the "comparable" error check until we encounter
an actual check between two non-comparable, non-nil values.
Note for the future: reflect makes it unnecessarily clumsy
to deal with nil values in cases like this. For instance, it
should be possible to check if a value is nil without stepping
around a panic. See the new functions isNil and canCompare
for my (too expensive) workaround.

The proposal as accepted in #34652 named the bit SkipFuncCheck.
It was renamed to DeferFuncCheck during the code review on a suggestion by Rob,
along with a comment to “defer type checking functions until template is executed,”
but this description is not accurate: the package has never type-checked functions,
only verified their existence. And the effect of the bit in this package is to eliminate
this check entirely, not to defer it to some later time.
I was writing code using this new bit and was very confused about when the
"type checking" was being deferred to and how to stop that entirely,
since in my use case I wanted no checks at all. What I wanted is what the bit does,
it just wasn't named accurately.
Rename back to SkipFuncCheck.

As part of #42026, these helpers from io/ioutil were moved to os.
(ioutil.TempFile and TempDir became os.CreateTemp and MkdirTemp.)
Update the Go tree to use the preferred names.
As usual, code compiled with the Go 1.4 bootstrap toolchain
and code vendored from other sources is excluded.
ReadDir changes are in a separate CL, because they are not a
simple search and replace.
For #42026.

The old ioutil references are still valid, but update our code
to reflect best practices and get used to the new locations.
Code compiled with the bootstrap toolchain
(cmd/asm, cmd/dist, cmd/compile, debug/elf)
must remain Go 1.4-compatible and is excluded.
Also excluded vendored code.
For #41190.

This allows multiline constructs like:
{{"hello" |
printf}}
Now that unclosed actions can span multiple lines,
track and report the start of the action when reporting errors.
Also clean up a few "unexpected <error message>" to be just "<error message>".
Fixes#29770.

Copy and adapt tests from text/template, to exercise more of html/template's copy.
Various differences in behavior are flagged with NOTE comments or t.Skip
and documented in #40075. Many of them are probably bugs.
One clarifying test case added to both text/template and html/template.
No changes to the package itself.
