99c17b970b gpgscm: Suppress warnings for GCC > 6.
* tests/gpgscm/scheme.c (CASE): Use unused attribute for GCC > 6.
(FALLTHROUGH): New for fallthrough.
(Eval_Cycle): Use FALLTHROUGH.  Remove not-needed comment of
fallthrough.

--

Since GCC combines C preprocessor macro expansion, the fallthrough
comment doesn't work well to suppress warnings for
-Wimplicit-fallthrough, near the macro CASE.  To handle this
problem, we use GCC's extension of unused label and fallthrough
attributes.

gpg: Ignore the multiple message override options.
* g10/gpg.c (oAllowMultisigVerification)
(oAllowMultipleMessages, oNoAllowMultipleMessages): Remove.
(opts): Turn --allow-multisig-verification, --allow-multiple-messages
and --no-allow-multiple-messages into NOPs
* g10/options.h (struct opt): Remove flags.allow_multiple_messages.
* g10/mainproc.c (proc_plaintext): Assume allow_multiple_messages is
false.
--

These options are very old compatibility hacks and should not be used
anymore.  We keep them as dummy options in case someone has them in
the conf file.

--

When gpg-agent detects homedir removal, it will automatically exit.
Then, call of 'gpgconf --kill all' will fail.  So, stop-agent should
be called before the removal of homedir.

This is a bug fix for Amelia Earhart who is probably in UTC-12.

When expiration date is specified, GnuPG interprets it as noon of the
date in local time.

Before this fix, the test compared the value by 2145916800 which is
2038-01-01 00:00:00 in UTC with allowance of 1 day.  When the test
was ran in UTC-12 timezone, it failed because of noon in the timezone
is midnight of the next day in UTC.

tests: Support tests that are expected to fail.
* tests/gpgscm/tests.scm (test-pool): Rework reporting.  Filter using
the computed test status instead of the return value.  Also print the
new categories 'failed expectedly' and 'passed unexpectedly'.
(test): If a test ends with a bang (!), it is expected to fail.  Adapt
status, status-string, and xml accordingly.
--

Allow tests to be marked as being expected to fail by appending a bang
(!) to the tests name.  If such a test fails, it will not be counted
as failure, but will still be prominently displayed in the report.  If
it succeeds unexpectedly, this is counted as a failure.

Fixes T3134.

TinySCHEME being a SECD-machine needs to push frames onto the dump
stack.  Previously, the dump stack was a list.  This required four
cells for the spine, as well as up to one additional cell to encode
the current opcode.  This was quite inefficient despite the fact that
we recovered the spine as well as the integer cell.

We introduce frame objects, which are a special variant of vectors of
length four.  Since the length is fixed, this frees up the length
field of the vector object to store the unboxed opcode.  A frame
object now fits in two cells.

Saving two or three cells is a mere byproduct, the performance gain
comes from increased locality, unboxed opcode representation, and the
ability to easily put the objects in a free list, keeping the garbage
collector out of the continuous motion of the virtual machine.
