NL_{ARG,LANG,MSG,SET,TEXT}MAX with newer POSIX.
Hide {FLT,DBL}_{DIG,MAX,MIN} and {PASS,TMP,NL_N}_MAX with newer XPG.
Make _POSIX_NGROUPS_MAX and _POSIX_OPEN_MAX conditional on the POSIX
version, like _POSIX_TZNAME_MAX already is.
Add some more _POSIX_* and _XOPEN_* 'specified' limits.

MI float.h which pulls in and defines the values that are needed from
there, and repair sys/limits.h so that it defines the values it needs
as well (depending on POSIX version, XPG version, etc).  guenther has
a more exact selection of that coming for limits.h.
this also fixes a few mistakes for the vax.

so that it can't get a signal while still running on the parent thread's
stack.  Also, pass in sizeof(struct __tfork) to provide forward compat
when more members are added.  This is an ABI change, so switch syscall
numbers and bump lib majors this time.

- everything that has prereq will also do includes, add it late, so that
gnu stuff (the only part with prereq) happens late.
- new RUN_MAKE snippet, to be able to have the makefile magically decide
between Makefile.bsd-wrapper and Makefile.
So there's no longer any need to remember complicated rules: add it to
RDIRS if it just wants make includes, add it to PRDIRS if it wants prereq too,
and that's all.

from the most recent version, use the implementation namespace for variables

friends in <time.h>.  The kernel needs access to the associated #defines, but
can't get them from <time.h>, so introduce a new header <sys/_time.h> and
include that from <time.h> for userland and <sys/time.h> for the kernel.
