This works around what appears to be either a kernel bug or a Go
runtime or syscall bug affecting certain Windows versions
(possibly all pre-2016?).
The retry loop is a simplified version of the one used in
cmd/go/internal/robustio. We use the same 2-second arbitrary timeout
as was used in that package, since it seems to be reliable in practice
on the affected builders. (If it proves to be too short, we can
lengthen it, within reason, in a followup CL.)
Since this puts a higher-level workaround in place, we can also revert
the lower-level workaround added to a specific test in CL 345670.
This addresses the specific occurrences of the bug for users of
(*testing.T).TempDir, but does not fix the underlying bug for Go users
outside the "testing" package (which remains open as #25965).

This is heavily based on CL 341336 by Joe Tsai and CL 351452 by
Jay Conrod.
T.Run and T.Name use a map[string]int64 to hold the next suffix to use
when duplicate names are passed to T.Run. This map necessarily retains
one entry per unique name. However, it's a waste of memory to retain
one entry per duplicate name: when we encounter the Nth duplicate, we
know that names 00 through N-1 have been used just by looking at N.
We do still need to store (and check for collisions againsts) explicit
names provided by the caller. For example, if the user passes in "a",
then "a#01", then "a" again, we cannot deduplicate the second "a" to
"a#01" — we need to instead skip ahead to "a#02". We can do so by
checking the count of "a", then generating a proposed deduplicated
name, then double-checking that proposed name against only the
explicit names so far.
This somewhat reduces memory usage for tests that spawn large numbers
of duplicate subtests, but doesn't solve the problem of memory growth
for fuzzing — we still have to track all of the explicit,
user-provided subtest names, and in a long-running fuzz test that set
alone may be unbounded.
This fixes memory growth for the example described in
https://golang.org/issue/44517#issuecomment-897104060,
but not the one in
https://golang.org/issue/44517#issuecomment-933825661.

When running benchmarks with high -count and no tests (either at all or
filtered with -run), the time for runTests to check for tests -count
times can add a significant delay to starting benchmarks.
To avoid this delay, make runTests bail out on the second iteration if
the first found no tests to run. We expect the same tests to run every
time, so there is no reason to duplicate work.
One caveat: the testing docs do not explicitly require the same subtests
to be run on every call, so this could break tests that depend on
multiple runs to actually run all tests. I consider such tests invalid,
but some may exist.

Previously, the methods Log, Logf, Failed, Name and
Skipped were the only (*common) methods that were

change, Failed and Name are still allowed, but
Log, Logf, and Skipped are not (t.Log, t.Logf, or

T.Run uses a map[string]int64 to keep track of subtest names that may
be returned through T.Name. T.Name can't return duplicate names for
subtests started with T.Run.
If a fuzz target calls T.Run, this map takes a large amount of memory,
since there are a very large number of subtests that would
otherwise have duplicate names, and the map stores one entry per subtest.
The unique suffixes are not useful (and may be confusing) since the
full sequence of tests cannot be re-run deterministically.
This change deletes all entries in the map before each call to the
function being fuzzed. There is a slight change in the contract of
T.Name while fuzzing.

This reverts commit 413c125da3.
Reason for revert: Giving this more thought, we've decided that
converting types under the hood may cause unexpected behavior to
users. This is a feature that can always be added after more
consideration has been done, but is not something that can be
removed due to the backwards compatibility promise.

This change refactors some of the code to support skipping a run
of the seed corpus by the go command before runFuzzing occurs.
Previously, the go command would run all seed corpus for all targets
that match the provided `run` argument. This will be redundant when
fuzzing a target. Now, the seed corpus is only run by targets other than
the one that's about to be fuzzed, and the worker handles running and
reporting issues with the seed corpus.
Part of the logic that needed close inspection is what to do if a
failure occurs during a testing-only or coverage-only fail. If the input
is already in the seed corpus, the fuzzing engine shouldn't add it. If
the input is currently in the cache, then it should be written to
testdata. In all cases, if an error occurs, we need to report this to
the user with enough information for them to debug it.
This uncovered some issues with our code when fuzzing without
instrumentation, and when -run=None was provided. There are some logic
fixes in this change, and some small refactors.

A fuzz worker process should exit with fuzzWorkerExitCode (70) if it
encounters an internal error.
This should generally only happen due to an I/O error on the worker
side. I can't think of a way to write a realistic test case for
this. test_fuzz_io_error.txt triggers an I/O error on the coordinator
side, which is similar.

I spent some time looking through all the changes we've made to
testing and cmd/go/... on the dev.fuzz branch. CL 348469 shows those
differences. This CL fixes comments, TODOs, and simplifies code in a
few places. It also implements F.Setenv.
