libc/amd64: 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.
Most of the amd64 assembler code jumps to .cerror using the GOT. It can jump to it directly now, as in non-PIC mode.
There are also some minor size optimizations to instructions but they yield virtually no benefit in the size of libc.so.7 due to padding.

We've been lax about matching END() macros in asm code for some time. This is used to set the ELF size attribute for functions. It isn't normally critical but some things can make use of it (gdb for stack traces). Valgrind needs it so I'm adding it in. The problem is present on all branches and on both i386 and amd64.

Update for AMD64 (repocopied from i386/sys/Ovfork.S - why is it O?) Depend on %rsi being preserved across the "syscall"-style syscall and strip out the PIC stuff (this cpu has full PC-relative addressing, at last!)

Cleanups after previous change: - Renumber labels since the previous revision removed one. - Remove useless and wrong comment. - Repeating the function name is just redundant. - The previous revision made the comment about %edx useless. - The comment about %eax was wrong (but did explain why %eax used to be fixed up).

The kernel already fixes up %eax for parents that return from fork, so don't bother manually fixing up %eax for the parent process by testing the value in %edx and zeroing and already zeroed %eax.

Remove _THREAD_SAFE and make libc thread-safe by default by adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in.
Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo
Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo.
Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible.
Remove uneeded includes of <errno.h> from a few files.
Add $FreeBSD$ to a few files in order to pass commitprep.

In libc_r, rename vfork syscall to _thread_sys_vfork and make vfork an alias to fork. It is difficult to do real vfork in libc_r, since almost every operation with file descriptsor changes _thread_fd_table and friends.
popen(3) works much better with this change.

Add support to enable libc to be compiled in ELF format. (#ifdef __ELF__) In a nutshell, this macroizes the local/global symbol scoping rules that are different in a.out and ELF. It also makes the i386 assembler stubs conform to i386 PIC calling conventions - the a.out ld.so didn't object, but the ELF one needs it as it implements PIC jumps via PLT's as well as calls. The a.out rtld only worked because it was accidently snooping the grandparent calling function's return address off the stack..
This also affects the libc_r code a little, because of cpp macro nesting.

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.
