Merge from gnulib, improving some licensing wording.
This clarifies and fixes some licensing issues raised by Glenn Morris <http://lists.gnu.org/archive/html/bug-gnulib/2011-09/msg00397.html>. It also merges the latest version of texinfo.tex and has some MSVC-related changes that don't affect Emacs. * Makefile.in (GNULIB_TOOL_FLAGS): Avoid msvc-inval, msvc-nothrow, pathmax, and raise, since these are needed only to address MSVC-related issues that Emacs doesn't have. * doc/misc/texinfo.tex, lib/dup2.c, lib/gnulib.mk, lib/signal.in.h: * lib/sigprocmask.c, lib/stat.c, lib/stdio.in.h, lib/sys_stat.in.h: * lib/unistd.in.h, m4/dup2.m4, m4/getloadavg.m4, m4/gl-comp.m4: * m4/include_next.m4, m4/signal_h.m4, m4/signalblocking.m4: * m4/stdint.m4, m4/stdio_h.m4, m4/sys_stat_h.m4, m4/time_h.m4: * m4/unistd_h.m4: Merge from gnulib.
