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.

most importantly, to not require a specific ordering of headers.

``-upper_bound % upper_bound''. Simplifies the code and makes it the
same on both ILP32 and LP64 architectures, and also slightly faster on
LP64 architectures by using a 32-bit remainder instead of a 64-bit
remainder.

use mquery to check for room to avoid getting an address we don't like
and having to send it back.
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.

on descriptors, this can be achieved thanks to the new getdtablecount()
system call. application may provide a reserve count to ensure that the
recvmsg() call is not called when they don't have enough descriptors to
work properly.
change the API so that transient errors that can be retried immediately
are retried within the function right away, whereas transient errors for
which the application may want to take action will set errno to EAGAIN.

preventing them being locally allocated as dynamic ports.
If AMT is configured with the same IP address as the host (and, in
the case of redirection/https ports, if the relevant feature is
enabled), it will steal packets sent to its ports.

These are useful if you're behind a bad nat with short timeouts as often
found in airport lounges and hotels. If the keepalives fail because the
network goes away (moving out of wireless reception, swapping cables etc)
your connections are more likely to drop so this is a double-edged sword.

This makes our <time.h> standards compliant except for some functions that are
still missing.

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.
