3913be8cf6 Rework the __vdso_* symbols attributes to only make the symbols weak,
but use normal references instead of weak.  This makes the statically
linked binaries to use fast gettimeofday(2) by forcing the linker to
resolve references and providing the neccessary functions.

8c121450bc Add API for obtaining extended machine context states that cannot be
fit into existing mcontext_t.

On i386 and amd64 do return the extended FPU states using
getcontextx(3). For other architectures, getcontextx(3) returns the
same information as getcontext(2).

d6b9b99e3b Convert softfloat to use the standard exception flag and rounding macros

Thanks to Ian Lepore for testing this patch.

064404aac9 Change index() and rindex() to a weak alias.
This allows people to still write statically linked applications that
call strchr() or strrchr() and have a local variable or function called
index.

6014007e00 Merge index() and strchr() together.
As I looked through the C library, I noticed the FreeBSD MIPS port has a
hand-written version of index(). This is nice, if it weren't for the
fact that most applications call strchr() instead.

Also, on the other architectures index() and strchr() are identical,
meaning we have two identical pieces of code in the C library and
statically linked applications.

Solve this by naming the actual file strchr.[cS] and let it use
__strong_reference()/STRONG_ALIAS() to provide the index() routine. Do
the same for rindex()/strrchr().

This seems to make the C libraries and static binaries slightly smaller,
but this reduction in size seems negligible.

9373f7b9c4 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.

33cfbb02c4 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.

3e324aa481 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'.

9d3703b842 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.
