* plugin/file: resolve each additional section target only once
additionalProcessing walked the answer and appended each target's address records without keeping track of the targets it had already resolved. An answer holding several records that point at one target, two MX records differing only in preference for instance, therefore repeated that target's A, AAAA and RRSIGs once per record. SRV, SVCB and HTTPS take the same path and behaved the same way. plugin/backend_lookup.go already skips targets it has seen; the file plugin never did.
Targets are compared in canonical form because SRV targets are not lowercased on insert, so one target can reach additional processing spelled two ways while the zone's tree still matches it case-insensitively. The map is allocated on first use, as additionalProcessing runs for every answer and most carry no target at all.
Fixes#6626

* plugin/file: move additional section tests to lookup_test.go
The cases exercise additionalProcessing, which lives in lookup.go, so they belong with the rest of the lookup tests. No test logic is changed.
Addresses review feedback.

Enable intrange linter to enforce modern Go range syntax over
traditional for loops, by converting:
for i := 0; i < n; i++
to:
for i := range n
Adding type conversions where needed for compatibility
with existing uint64 parameters.

From RFC 1034 ...
Wildcard RRs do not apply:
[...]
When the query name or a name between the wildcard domain and
the query name is know to exist. For example, if a wildcard
RR has an owner name of "*.X", and the zone also contains RRs
attached to B.X, the wildcards would apply to queries for name
Z.X (presuming there is no explicit information for Z.X), but
not to B.X, A.B.X, or X.

Uppercase all these test errors as well. And extend the presubmit to
check for these in the future. Also do a slightly smarter grep to only
get t.<something>. as (because dump regexp) this also grep over non test
files.
* global: move to context
Move from golang.org/x/net/context to std lib's context.
Change done with:
for i in $(grep -l '/context' **/*.go); do sed -e 's|golang.org/x/net/context|context|' -i $i; echo $i; done
for i in **/*.go; do goimports -w $i; done
* drop from dns.pb.go as well
Add a full test server impl in this new package + tests. Move
dnsrecorder into this package as well and finish up the commented out
tests that were left in the old dnsrecorder package.
Update all callers and tests.
* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat
