- introduce PROC_STOPPED flag, which tracks whether the process is
stopped on PROC_STOP in the kernel, rather than implicitly deriving
this from PM_SIG_PENDING;
- make the process resumption test based on current state rather than
state transitions;
- add and clarify several flag checks in the signal handling code;
- add test79 to test signal handling robustness.

. add all sys/sys headers not already present to help compiling
. take netbsd dirent.h and struct dirent; main result is
introducing d_type and d_namlen that have to be set by getdents()
in all FS code implementing it
. d_off is gone
. alignment of the struct has become 8 bytes instead of 4
. remove _MAX_BLOCK_SIZE, _MIN_BLOCK_SIZE, _STATIC_BLOCK_SIZE
. libminlib: cleanup unused yet duplicate code
. mfs: throw out the long-broken v1, v2 support
. new test for dirent contents filled by getdents()

When installed, the test scripts lose their ".sh" suffix, causing them
to be skipped by the "run" script. With this patch, the tests are no
longer specified with ".sh" suffix in the run script, and the suffix
is added automatically as necessary.
LSC: Minor adaptation to keep track of history. As this patch has been
forward ported into mainline, a simple rebase would loose this
commit (cf commit 1f317d315c).

Forward-port of the run script change in the testvnd
commit on the 3.3.0 branch by David.
Needed to cleanly run the testisofs test as root in
the Jenkins environment.
'While here,' also fix messy which output in testsh2.

testmfs: catch MFS format changes
This test tests mkfs.mfs will generate the same FS image given the same
input files. mkproto creates a proto file (normalizing directory entry
order). The assumption is that a change in the output flags a tacit
change in FS format, and that a FS format change will cause the image
to change.
. Changes to mkfs.mfs that innocently change the format can
change the sha1 output in the script along with it.
. The assumption is that corresponding versions of mkfs.mfs and
MFS will always work together; otherwise a lot breaks (ramdisk etc.)
. Therefore, as long as a generated FS image stays the same with the
same input now, incompatible MFS changes will still be flagged,
even if they work together with the current mkfs.mfs.
testisofs: test ISO filesystem
. to test isofs: prepare an ISO FS image using writeisofs, copy it
to a RAM device, mount it using the iso9660fs server, compare the
SHA1 contents of the files on the ISO with the inputs.
. use su to run certain commands in the script as root
run script: run shell script tests
. they are installed without .sh so should be
searched for as such
. add diagnostic when tests are skipped

. turns on mmap() functionality for files by default
. also causes exec() to use it to map in executables
without copying and with sharing those pages with the
disk cache and other instances of the executable

. test74 for mmap functionality
. vm: add a mem_file memory type that specifies an mmap()ped
memory range, backed by a file
. add fdref, an object that keeps track of FD references within
VM per process and so knows how to de-duplicate the use of FD's
by various mmap()ped ranges; there can be many more than there can
be FD's
. turned off for now, enable with 'filemap=1' as boot option

This commit removes the secondary cache code implementation from
VM and its usage from libminixfs. It is to be replaced by a new
implementation.

. test70: regression test for m_out vfs race condition
The following tests use testcache.c to generate test i/o
patterns, generate random write data and verify the reads.
. test71: blackbox full-stack test of FS operation, testing
using the regular VFS interface crazy i/o patterns
with various working set sizes, triggering only
primary cache, also secondary cache, and finally
disk i/o and verifying contents all the time
. test72: unit test of libminixfs, implementing
functions it needs from -lsys and -lblockdriver
and the client in order to simulate a working
cache client and backend environment.
. test73: blackbox test of secondary vm cache in isolation
Change-Id: I1287e9753182b8719e634917ad158e3c1e079ceb
. add -l option to list available tests
. add -t option to specify tests to run
. also improve the root check a bit by
not relying on an environment var
. do not print the human-friendly banner & summary
if a test list is given to make the test
results easy to parse

test69 requires superuser powers to adjust the time. This caused
the test to fail when run as a normal user. The patch adds test69
to the setuid list which will allow regular users to execute it.
Patch contributed by Antoine Leca.
. also make other out-of-memory conditions less fatal
. add a test case for a user program using all the memory
it can
. remove some diagnostic prints for situations that are normal
when running out of memory so running the test isn't noisy
. so that functionality is tested
. add test63 that actually tests dlopen(), dlsym(),
etc. functionality; only built if clang supports it
. also test10 test to copy more of the executable
Previously, user processes could cause a kernel panic upon FPU state
restore, by passing bogus FPU state to the kernel (through e.g.
sigreturn). With this patch, the process is now sent a SIGFPE signal
instead.
