4adc354c34 Add amd64 versions of makecontext() and signalcontext() needed
for libkse (makecontext() is also needed for libthr).
These probably will need some tweaking.

cf2720dda4 Turn off alloca.S - it cannot possibly work like this since on AMD64, gcc
doesn't use stack frames.  It uses offsets relative to %rsp, not %rbp.  So
we cannot just change %rsp like this.

9ed358fddc Disconnect the userland get/set/swapcontext() functions from
libc.  I want to keep these in some version for the thread
library/ies, but don't know whether to have them repo-copied
to libc_r or renamed and kept in libc.

Change the name of an alpha macro that was changed with the
system call commit.

cc2dbb21e5 Move swapcontext.c to the ${MACHINE_ARCH}/gen/Makefile.inc area, otherwise
it causes undefined references to getcontext() and setcontext() on
platforms other than i386 and alpha.

b66b8326e5 Add getcontext, setcontext, makecontext, and swapcontext. These
functions are defined in SUSv2 and the latest POSIX spec.

Thanks to Bernd Walter <ticso@cicely8.cicely.de> for helping debug my
alpha assembly.

c932e5d18f rfork(2) wrapper for simple rfork-style threads. I have lost count of
the number of times I have given this to people and got asked: why isn't
it in libc?  It is impossible to do this without assembler glue to reset
the stack for the new child process.

int rfork_thread(flags, stack_addr, start_fnc, start_arg)
int flags;                 Flags to rfork system call.  See rfork(2).
void *stack_addr;          Top of stack for thread.
int (*start_fnc)(void *);  Address of thread function to call in child.
void *start_arg;           Argument to pass to the thread function in child.

This is deliberately not documented or prototyped in includes until the
corresponding alpha version is written.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

717d9cdd57 First round of changes to clean up the RCSID mess in libc:
1) Changed LIB_SCCS and SYSLIB_SCCS to LIB_RCS and SYSLIB_RCS.
2) Changed sccsid[] variables to rcsid[]
3) Moved all RCSID strings into .text
4) Converted all SCCSID's to RCS $Id$'s
5) Added missing $Id$'s after copyright.

11841a6877 Put __infinity back here again until someone does the right thing and
repartitions libc into something human again.  I don't have that kind of

2ceb2ce9ee First crack at making libc work with the new make macros. It compiles on
my machine, and a simple static (genassym) and shared (sysctl) executable
both work.  Still to be done: RPCand YP merge.
