65d8b7120d Disconnect non-MPSAFE SMBFS from the build in preparation for dropping
GIANT from VFS. In addition, disconnect also netsmb, which is a base
requirement for SMBFS.

In the while SMBFS regular users can use FUSE interface and smbnetfs
port to work with their SMBFS partitions.

Also, there are ongoing efforts by vendor to support in-kernel smbfs,
so there are good chances that it will get relinked once properly locked.

This is not targeted for MFC.

85c1a64cec Disconnect non-MPSAFE NTFS from the build in preparation for dropping
GIANT from VFS. This code is particulary broken and fragile and other
in-kernel implementations around, found in other operating systems,
don't really seem clean and solid enough to be imported at all.
If someone wants to reconsider in-kernel NTFS implementation for
inclusion again, a fair effort for completely fixing and cleaning it
up is expected.

In the while NTFS regular users can use FUSE interface and ntfs-3g
port to work with their NTFS partitions.

3f4806915e Disconnect non-MPSAFE NWFS from the build in preparation for dropping
GIANT from VFS. In addition, disconnect also netncp, which is a base
requirement for NWFS.

In the possibility of a future maintenance of the code and later
readd to the FreeBSD base, maybe we should think about a better location
for netncp. I'm not entirely sure the / top location is actually right,
however I will let network people to comment on that more specifically.

This is not targeted for MFC.

52e7fd7c54 Add support for bmake. This includes:
1.  Don't do upgrade_checks when using bmake. As long as we have WITH_BMAKE,
    there's a bootstrap complication in ths respect. Avoid it. Make the
    necessary changes to have upgrade_checks work wth bmake anyway.
2.  Remove the use of -E. It's not needed in our build because we use ?= for
    the respective variables, which means that we'll take the environment
    value (if any) anyway.
3.  Properly declare phony targets as phony as bmake is a lot smarter (and
    thus agressive) about build avoidance.
4.  Make sure CLEANFILES is complete and use it on .NOPATH. bmake is a lot
    smarter about build avoidance and should not find files we generate in
    the source tree. We should not have files in the repository we want to
    generate, but this is an easier way to cross this hurdle.
5.  Have behavior under bmake the same as it is under make with respect to
    halting when sub-commands fail. Add "set -e" to compound commands so
    that bmake is informed when sub-commands fail.
6.  Make sure crunchgen uses the same make as the rest of the build. This
    is important when the make utility isn't called make (but bmake for
    example).
7.  While here, add support for using MAKEOBJDIR to set the object tree
    location. It's the second alternative bmake looks for when determining
    the actual object directory (= .OBJDIR).

c9ef684bc2 Fix some memory allocation errors:
* jail_setv will leak a parameter name if jailparam_import fails.
* jailparam_all loses the jailparam pointer on realloc error
  (a clear freshman mistake).
* If jailparam_init fails, the caller doesn't need to jailparam_free
  the buffer.  That's not really clear, so set things to NULL allowing
  jailparam_free to work without error (though it's still not required).

322c7845da rpc: convert all uid and gid variables to u_int.
After further discussion, instead of pretending to use
uid_t and gid_t as upstream Solaris and linux try to, we
are better using u_int, which is in fact what the code
can handle and best approaches the range of values used
by uid and gid.

09939583a7 The ioctl VM_GET_MEMORY_SEG is no longer able to return the host physical
address associated with the guest memory segment. This is because there is
no longer a 1:1 mapping between GPA and HPA.

length of the lowmem and highmem segments.

18dd2c0d51 Change vm_malloc() to map pages in the guest physical address space in 4KB
chunks. This breaks the assumption that the entire memory segment is
contiguously allocated in the host physical address space.

This also paves the way to satisfy the 4KB page allocations by requesting
free pages from the VM subsystem as opposed to hard-partitioning host memory
at boot time.

The previous change (based on Solaris) doesn't work properly either
as the casting only has the effect of quieting the compiler.

d142b7417c rpc: convert all uid and gid variables of the type uid_t and gid_t.
As part of the previous commit, uses of xdr_int() were replaced
with xdr_u_int(). This has undesired effects as the second
argument doesn't match exactly uid_t or gid_t. It also breaks
assumptions in the size of the provided types.

To work around those issues we revert back to the use of xdr_int()
but provide proper casting so the behaviour doesn't change.

While here fix a style issue in the affected lines.

fba61ef227 libc: Use O_CLOEXEC for various internal file descriptors.
This fixes a race condition where another thread may fork() before CLOEXEC
is set, unintentionally passing the descriptor to the child process.

This commit only adds O_CLOEXEC flags to open() or openat() calls where no
fcntl(fd, F_SETFD, FD_CLOEXEC) follows. The separate fcntl() call still
leaves a race window so it should be fixed later.

f702d078aa libc/fts: Use O_CLOEXEC for internal file descriptors.
Because fts keeps internal file descriptors open across calls, making such
descriptors close-on-exec helps not only multi-threaded applications but
also single-threaded applications.

In particular, this prevents passing a temporary file descriptor for saving
the current directory to processes created via find -exec.

e4c096aeb4 sigaction(2),sigwait(2),sigwaitinfo(2): Remove [EFAULT] error condition.
Passing an invalid pointer results in undefined behaviour.

The wrappers in libthr access some of the data pointed to by the arguments
in userland, so that an invalid pointer will cause a signal and not an
[EFAULT] error return.

Furthermore, if the [EFAULT] error occurs when the kernel is writing, it is
not a proper error in the sense that the call still commits (changing the
signal disposition or accepting the signal).
