- Copy stable/10 (r259064) to releng/10.0 as part of the 10.0-RELEASE cycle. - Update __FreeBSD_version [1] - Set branch name to -RC1
[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so start releng/10.0 at '100' so the branch is started with a value ending in zero.

libc/i386: Do not export .cerror.
For some reason, libc exports the symbol .cerror (HIDENAME(cerror)), albeit in the FBSDprivate_1.0 version. It looks like there is no reason for this since it is not used from other libraries. Given that it cannot be accessed from C and its strange calling convention, it is rather unlikely that other things rely on it. Perhaps it is from a time when symbols could not be hidden.
Not exporting .cerror causes it to be jumped to directly instead of via the PLT.
This change also takes advantage of .cerror's new status by not saving and loading %ebx before jumping to it. (Therefore, .cerror now saves and loads %ebx itself.) Where there was a conditional jump to a jump to .cerror, the conditional jump has been changed to jump to .cerror directly (many modern CPUs don't do static prediction and in any case it is not much of a benefit anyway).
This change makes libc.so.7 a few kilobytes smaller.

Add missing END() macros, as per rev 184547 for amd64. The lack of these is mostly harmless, but it does upset some of valgrind's functionality.

Use 'mov' instead of 'lea' for setting the syscall number in %eax as that is clearer about what we are actually doing.

Fix some rather interesting bugs that managed to not turn up in various testing and real-life applications: 1) If you returned from the thread function, you got a segv instead of calling _exit() with your return code. 2) clean up some bogus stack management. There was also an underflow on function return. 3) when making syscalls, the kernel is expecting to have to leave space for the function's return address. We need to duplicate this. It was an accident that the rfork syscall actually worked here. :-/

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.
