6232589aeb Replace a proliferation of buggy MD implementations of modf() with a
working MI one.  The MI one only needs to be overridden on machines
with non-IEEE754 arithmetic.  (The last supported one was the VAX.)
It can also be overridden if someone comes up with a faster one that
actually passes the regression tests -- but this is harder than it sounds.

ba8d74d95f Fix bzero() for 64-bit.
The existing implementation of bzero incorrectly clears bytes when the
start address is not word aligned. Fix it by using REG_SHI macro which
works on both 32 and 64 bit.

2f9f616df9 Reinstate the ptrace patch to restore the 'gp' register after calling
a function. I made a mistake in assuming that the .cprestore directive
will cause the assembler to automatically restore 'gp' after the 'jalr'.

The .cprestore directive does its magic only after 'jal' and 'bal'
instructions - not the 'jalr'.

All suggested by Neel.

1de48bf3a3 This fixes a bug found and fixed by JC. Basically
no save was being done of the ra and gp pointers
before we call the __error function.

dc428c2ffe Remove unneeded stdlib directories.
It's not necessary to add stdlib directories for each architecture, even
if the architecture doesn't implement any files of its own.

21fc9f2bcc These warnings are only relevant on NetBSD it seems. They don't seem
to be relevant to FreeBSD at all.

51cbd5d9d7 These symbols don't belong here. Remove them. Since mips hasn't had
a release, I think there's no impact here...

a1b5a8955e Mark uname(), getdomainname() and setdomainname() with COMPAT_FREEBSD4.
Looking at our source code history, it seems the uname(),
getdomainname() and setdomainname() system calls got deprecated
somewhere after FreeBSD 1.1, but they have never been phased out
properly. Because we don't have a COMPAT_FREEBSD1, just use
COMPAT_FREEBSD4.

Also fix the Linuxolator to build without the setdomainname() routine by
just making it call userland_sysctl on kern.domainname. Also replace the
setdomainname()'s implementation to use this approach, because we're
duplicating code with sysctl_domainname().

I wasn't able to keep these three routines working in our
COMPAT_FREEBSD32, because that would require yet another keyword for
syscalls.master (COMPAT4+NOPROTO). Because this routine is probably
unused already, this won't be a problem in practice. If it turns out to
be a problem, we'll just restore this functionality.
