Fix .LIBPATTERNS for MS-Windows builds.

default.c (.LIBPATTERNS) [__CYGWIN__ || WINDOWS32]: Provide
library patterns for MS-Windows.

Copyright-paperwork-exempt: yes
* main.c (die): Close output_context AND make_sync.

die() can be invoked inside a separate output_context, if the
$(error ...) function is expanded as part of a recipe.
* commands.c: [SV 40789] Remove unneeded header dlfcn.h
Allow the EMX build to use output_sync.

job.c (start_job_command): Move the child output diversion out
of non-EMX branch.
[__EMX__]: Don't use fixed FD_STDOUT and FD_STDERR in the call to
child_execute_job.

Copyright-paperwork-exempt: yes
* configure.ac: [SV 40790] Fix load autoconf variables.

Copyright-paperwork-exempt: yes
* job.c (set_child_handler_action_flags): [SV 41341]

Ensure signal handler is in place before alarm(1).
Improve error reporting in the Windows port when env size is too large.

w32/subproc/misc.c (arr2envblk): Compute and return the size of
the environment passed to child process.

w32/subproc/sub_proc.c (process_begin): If the call to
CreateProcess failed with EINVAL, and the required environment
size was larger than 32KB, assume it's a Windows XP limitation,
and display an error message to that effect.

w32/subproc/proc.h (arr2envblk): Update prototype.

Copyright-paperwork-exempt: yes
* output.c: Ensure space for final nul byte in fmtbuf.

Copyright-paperwork-exempt: yes
* configure.ac: Fixup for newer autoconf/automake
* Rename MAP_PATHSEP to MAP_DIRSEP.
[SV 42249] Propagate correct rule status results.

* remake.c (update_file, update_file_1, check_dep): Return an enum
  update_status value instead of an int, and keep the highest value we
  find as we walk the graph so that the ultimate status is correct.
* tests/scripts/options/dash-q: Add a test for updating prerequisites.
NMakefile.template ($(OUTDIR)/posixfcn.obj): Fix a typo.

debian: import from 3.81
debian: diverge the control file.
Alternate debian/rules -- use CDBS.
