commit bc444e5aa4 introduced a call to get_posix_access()
with a NULL pointer for the mode_t parameter because the value
is not needed later on... entirely ignoring the fact that the
mode_t bits are checked for the object being a directory.
In turn, the get_posix_access() call never checked for default
ACEs and returned only the standard ACEs. Thus, every chmod call
on a directory dropped the default ACEs from its permissions, as
well as the default NULL deny-ACE used to store specific bits.
It got also impossible to set the sgid bit on directories.

Older coreutils created directories with mode bits filtered through
umask. Newer coreutils creates directories with full permissions,
0777 by default.
This new coreutils behaviour uncovered the fact that default ACEs for
newly created directories were not filtered by umask starting with
commit bc444e5aa4.
Fix it by applying umask on the default ACEs.

A recent binutils version introduced `libsframe` and made it a
dependency of `libbfd`. This caused a linker problem in the MSYS2
project, and once Cygwin upgrades to that binutils version it would
cause the same problems there.
Let's preemptively detect the presence of `libsframe` and if detected,
link to it in addition to `libbfd`.

The new loop in open_shared has a subtil performance problem.
Next_address is bumped only if mapping at this address
failed. Every subsequent call to open_shared has a high probability
having to call MapViewOfFileEx twice, because next_address is still
set to the address of the last successful mapping.
Avoid this by bumping next_address every time.
While at it, fix a comment.

With the previous commit 9ddd48ee1b ("Cygwin: /proc/<PID>/maps:

the standard shared regions (cygwin, user, myself, shared console)

addresses anymore, so drop the definitions and simplify open_shared.

So far, the addresses printed for the shared regions of a process
were faked. The assumption was that the shared regions are always
in the same place in all processes, so we just printed the addresses
of the current process. This is no safe bet. The only safe bet is
the address of the cygheap. So keep track of the addresses in the
cygheap and read the addresses from the cygheap of the observed
processes. Add output for the shared console.

vmstat from proc-ps-4.0.x prints "Unable to create system stat structure"
if the /proc/cpuinfo output fails to contain topology info. While
Linux always prints topology info if the kernel has been built with
CONFIG_SMP, Cygwin only prints topology info if the CPU is known to
be multi-core (i. e., the HT feature flag is set).
Fix that by printing topology info all the time, even for single-core
CPUs.

Build all the testcase executables directly using automake, rather than
passing the compiler information into DejaGnu to have it build them.
(This means you get build avoidance for these executables, so they only
get built once, rather than every time you run the test, and makes it
much easier to run them in isolatation against the installed Cygwin,
which is really nice to have when trying to fix broken tests...)
Rename the 'cygrun' subdirectory to 'mingw', and build all the testsuite
MinGW executables there.
Drop sample-miscompile.c (testing that compile failure is detected is
perhaps useful, but not here...)
objdir isn't a predefined output variable in Automake (any more?), so
this was just using the absolute path /testsuite as the test's temporary
directory. Use builddir instead.
