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.

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.

Fixed comparisons so that preposterously large (>= 0x80000000) brk values aren't silently converted to minbrk. This stops malloc(INT_MAX) from dumping core. Small values are still silently converted. They should be an error. sbrk() doesn't do any range checking or conversions or overflow checking.
Moved PIC_EPILOGUE invocation to a more natural place where it obviously doesn't interfere with the comparison.

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 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.

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.
