c54917029b Make __dtoul() actually DTRT. The calling convention was totally wrong, and 
the `big' value should be 2^63, not 2^31.
Also, nuke __fixunsdfsi(), since this is never output by the sparc64 compiler.

e740400671 Just use a store/load pair to get the pattern into the FP reg. This eliminates 
a bunch of cruft and avoids using a v9a instruction.
In addition, eliminate 8 of the fmovda's, which we are not using the result of
anyway.
Net result is that this should be faster in all cases.

985033a7a6 Add fixunssfsi and fixunsdfsi. These are provided by libgcc2.c in GCC 2.95, 
but not in EGCS.

This version of fixunssfsi is almost exactly the arm32 version.  fixunsdfsi is
mostly based on fixdfsi, but with simplifications for 64-bit integers.

Only minimal testing has been applied so far.

without too much hacking, assuming doubles and u_int64_ts are passed and
returned the same way, and FP formats are IEEEish.

bedc7b48df Add syscall stubs for __vfork14(). These are basically copies of Ovfork.S 
with the syscall numbers changed.

Since 4.4BSD vfork(2) did not share address space, Ovfork.S could be changed
to be identical to fork.S (modulo syscall numbers).  __vfork14.S, however,
needs to remain separate since with a shared address space, the stub needs to
pre-decrement the stack and do an indirect jump to the return address, so that
the shared stackframe is still there when the parent returns.  (Obviously,
this does not apply to systems which to not build stackframes on leaf calls.)

eb96023de7 Quick fix to repair runtime link problem with libc - "SYS_sigaltstack 
undefined".  The sigaltstack structure layout didn't actually change on
the sparc, so just change the syscall name.  A better fix would probably
be to replace the direct system call with a function call to the libc
sigaltstack().

0053558a70 Fix a glaring bug in the assembly stubs for memcpy() and memmove() that 
meant the src address was being returned rather than the dst address.
Spotted by Chris Demetriou.

4d7e773266 A foolish consistency... gen, net, and string all get MD sources 
specified by including a Makefile.inc from the appropriate MD directory.
stdlib doesn't do that, but there's no reason that it shouldn't (and
it'd be nice to eliminate the 'if's from the MI stdlib Makefile.inc).
