    html/template: fix multiple Clones of redefined template
    
    This change redoes the fix for #16101 (CL 31092) in a different way by
    making t.Clone return the template associated with the t.Name() while
    allowing for the case that a template of the same name is define-d.
    
    Fixes #17735.

    all: spell "marshal" and "unmarshal" consistently
    
    The tree is inconsistent about single l vs double l in those
    words in documentation, test messages, and one error value text.
    
            $ git grep -E '[Mm]arshall(|s|er|ers|ed|ing)' | wc -l
                  42
            $ git grep -E '[Mm]arshal(|s|er|ers|ed|ing)' | wc -l
                1694
    
    Make it consistently a single l, per earlier decisions. This means
    contributors won't be confused by misleading precedence, and it helps
    consistency.
    
    Change the spelling in one error value text in newRawAttributes of

    html/template, text/template: drop defined template list from errors
    
    The report in #17414 points out that if you have many many templates,
    then this is an overwhelming list and just hurts the signal-to-noise ratio of the error.
    
    Even the test of the old behavior also supports the idea that this is noise:
    
            template: empty: "empty" is an incomplete or empty template; defined templates are: "secondary"
    
    The chance that someone mistyped "secondary" as "empty" is slim at best.
    
    Similarly, the compiler does not augment an error like 'unknown variable x'
    by dumping the full list of all the known variables.
    
    For all these reasons, drop the list.
    
    Fixes #17414.

    html/template, text/template: docs and fixes for template redefinition
    
    All prior versions of Go have allowed redefining empty templates
    to become non-empty. Unfortunately, that has never consistently
    taken effect in html/template after the first execution:
    
            // define and execute
            t := template.New("root")
            t.Parse(`{{define "T"}}{{end}}<a href="{{template "T"}}">`)
            t.Execute(w, nil) // <a href="">
    
            // redefine
            t.Parse(`{{define "T"}}my.url{{end}}`) // succeeds, but ignored
            t.Execute(w, nil) // <a href="">
    
    When Go 1.6 added {{block...}} to text/template, that loosened the
    redefinition rules to allow redefinition at any time. The loosening was
    undone a bit in html/template, although inconsistently:
    
            // define and execute
            t := template.New("root")
            t.Parse(`{{define "T"}}body{{end}}`)
            t.Lookup("T").Execute(ioutil.Discard, nil)
    
            // attempt to redefine
            t.Parse(`{{define "T"}}body{{end}}`) // rejected in all Go versions
            t.Lookup("T").Parse("body") // OK as of Go 1.6, likely unintentionally
    
    Like in the empty->non-empty case, whether future execution takes
    notice of a redefinition basically can't be explained without going into
    the details of the template escape analysis.
    
    Address both the original inconsistencies in whether a redefinition
    would have any effect and the new inconsistencies about whether a
    redefinition is allowed by adopting a new rule: no parsing or modifying
    any templates after the first execution of any template in the same set.
    Template analysis begins at first execution, and once template analysis
    has begun, we simply don't have the right logic to update the analysis
    for incremental modifications (and never have).
    
    If this new rule breaks existing uses of templates that we decide need
    to be supported, we can try to invalidate all escape analysis for the
    entire set after any modifications. But let's wait on that until we know
    we need to and why.
    
    Also fix documentation of text/template redefinition policy
    (redefinition is always OK).
    
    Fixes #15761.

    html/template: fix Clone so that t.Lookup(t.Name()) yields t
    
    Template.escape makes the assumption that t.Lookup(t.Name()) is t
    (escapeTemplate looks up the associated template by name and sets
    escapeErr appropriately).
    
    This assumption did not hold for a Cloned template, because the template
    associated with t.Name() was a second copy of the original.
    
    Add a test for the assumption that t.Lookup(t.Name()) == t.
    
    One effect of this broken assumption was #16101: parallel Executes
    racily accessed the template namespace because each Execute call saw
    t.escapeErr == nil and re-escaped the template concurrently with read
    accesses occurring outside the namespace mutex.
    
    Add a test for this race.
    
    Related to #12996 and CL 16104.
    
    Fixes #16101
